COVER ADVERTISER: Steve Franklin, founder of Eltirus explains what value artifical intelligence and machine learning can provide, specifically in relation to leveraging intellectual property and domain knowledge for the quarrying industry.
EVERY MONTH
It’s an exciting time for the Quarry team. We have recently expanded the editorial line-up to better cover the growing quarrying industry.
I am no stranger to quarrying, having covered it as part of my beat at the Australian Bulk Handling Review. It’s a fascinating, vital industry which is in the middle of several exciting (and potentially revolutionary changes).
Technological advances and changing industry attitudes across all sectors are presenting entirely new ways of doing business. Increased productivity, safety, and sustainability are just the beginning.
The Industrial Internet of Things is made up of several technologies, all working in tandem to provide operators with enhanced information and a deeper understanding of their system.
In this edition of Quarry, we look at how this technology is being deployed in the field, and what the potential implications could be.
Vital to this role are sensors, which are the eyes and ears of digital
systems. They collect the crucial data that can then be fed into cloudbased computers. Quarries can use this data to predict maintenance needs, spot anomalies and plan for the future.
This software often includes artificial intelligence (AI) and machine learning. The industry is still in the early stages of learning exactly how advanced this software can be.
Steve Franklin, the founder of Eltirus, explores the potential benefits and limitations of artificial intelligence, machine learning and language models in this month’s cover story. He uses ChatGPT as part of his research into how business can best take advantage of these AI tools.
We hope you enjoy reading the October edition and find it insightful.
I would also like to thank the editorial team, including Adam Daunt and Paul Hayes, for their support in growing the magazine.

Safety is one of the most important factors for the quarrying industry – and while we have had great success improving the physical safety in the industry, there is still much to be done when it comes to psychosocial hazards.
They’re not a new phenomenon. They’re anything that can cause psychological harm, including poor support, bullying, harassment, remote or isolated work, and many more.
These come together and make life much more stressful for everyone involved. Regular, intense, or prolonged stress can cause real harm – including anxiety, depression, post-traumatic stress disorder, sleep disorders, and lead to physical harm such as musculoskeletal injuries, chronic disease, or fatigue related injuries.
We also know the impact these hazards can have on income, company revenue and the broader community.
According to the latest data from the Australian Bureau of Statistics, 197,000 working days were missed in 2022 in Australia due to workplace conflict.
For business owners, the Governments’ Productivity Commission 2020 found mental health issues cost $220B annually, the ongoing cost and mental health impact of COVID19 and the years that have followed are yet to be quantified.
We don’t need to see these statistics to understand how deeply psychosocial injury can affect someone.
It leads to dread about going to work, not feeling safe to be ourselves, or feeling as if a job is under constant threat.
We can all do our part to eliminate these psychosocial risks. A big part of that is embracing a diverse and welcoming workplace. Nobody wants to be the reason for someone else’s poor mental health.
A diverse workplace is one that welcomes people of any ethnicity, religion, age, sexual preference, and gender. It’s one where people feel comfortable to be themselves around colleagues. It reduces stress people feel and leads to more innovation, more productivity, and most importantly, a safer industry overall.
Diversity and inclusion is a key strategic objective for the IQA, and we are encouraging the industry to build a skilled workforce that embraces it.
It was also heart-warming to see the industry embrace the issue of psychosocial safety at the recent safety conference in Newcastle, which had record attendance. There, we heard regulator priorities and tackled some serious topics.
Everyone at a quarry site can help reduce psychosocial hazards at work. In many cases, a conversation could be the thing that changes a life. Reach out to your colleagues and see if they are doing okay.
It’s important to listen, encourage them to seek further support if they need it, and to check in. There are excellent resources available online at RUOK’s website.
If you yourself need someone to talk to, you can contact Lifeline at 13 11 14.

“We couldn’t be prouder of him (and his dad!) for this fantastic achievement. Be sure to shake his paw the next time you see him! Thank you to everyone who voted for him.”
“Terry is such a hard worker who takes his job very seriously and always ensures he does his site inspections, pest deterrence, pre-start checks and that everyone goes home with an empty lunchbox.
“We couldn’t be prouder of our pawsome CQO (chief quarry officer).”
Terry’s owner and quarry manager, Jaie Wilson, spoke to the New Zealand Herald about scooping the award.
“My general manager [Sam Atkinson] up in Auckland asked if she could enter Terry in the competition, so I said yes, thinking nothing of it. I didn’t think he could actually win, but he is a special character,” he told the New Zealand Herald
Atiamuri Sand and Pumice, a quarrying business in New Zealand, nominated Terry – a seven-year-old Jack Russell cross smooth fox terrier – for the nation’s top award.
The workers love Terry as the assistant quarry manager after going to work since he was a puppy.
Atiamuri Sand and Pumice has celebrated Terry’s national honour in style.
“We are thrilled to share that Terry is the #NZTOPDOG winner,” they posted on Facebook.
“He comes hunting with me and is happy to go for a ride on anything, four wheelers, boats, machinery … ever since he was a puppy, he always wanted to be with me.
“He’s a third generation … I’m getting close to getting him a girlfriend because he has good genes and a nice temperament.” •
The success of the Australian Matildas on home soil has captured Komatsu after re-signing with the Western Sydney Wanderers.
The Wanderers have found a long-term partner in Komatsu, tied together until 2026 after signing in 2021.
Komatsu will retain its position on the right sleeve of the Wanderers Liberty A-Leagues home, away and third jerseys. It will also support several female-focused events run by the Wanderers.
Komatsu chief executive Sean Taylor said the company was committed to expanding its diversity.
“A big focus for us at Komatsu has always been furthering diversity and inclusion,” Taylor said.
“This sponsorship is a way for us to align ourselves with a strong sporting brand that also supports a diverse and inclusive workplace and allows us to shine a light on the diverse career opportunities available in mining and construction.
“Women’s sport, and football in particular, is receiving the recognition it deserves, thanks to the FIFA Women’s World Cup on our shores and the Matildas energising and uniting the nation.
“We’re looking forward to supporting the sport by partnering with the Wanderers Women’s team.”
The two brands share commonalities on and off the field as they inspire women in the workforce. Like Komatsu within construction and mining, WSW has been
firmly focused on diversity and raising women’s profile in the sport.
Western Sydney Wanderers are the pride of Western Sydney, while Komatsu’s head office is in Fairfield in Sydney’s west.
Western Sydney Wanderers chief executive Scott Hudson said the partnership was strong.
“We are delighted to continue our fruitful relationship with Komatsu after a successful first two years,” Hudson said.
“Like the Wanderers, Komatsu are based in Western Sydney, and we look forward to working closely with them over the next two seasons to continue to support our women’s programs.”•
Victoria achieved 70 million tonne of quarry production in 2021-22.
The Approvals Coordination role has undergone a pilot phase. During this period, the government believes 40 million tonnes of extra quarry material were acquired. This role is designed to help quarries achieve approvals like increased operating hours or approved quarry applications.
It comes after the Victorian Government officially unveiled Resources Victoria, which was enacted on July 31.
The central body will regulate the quarrying and resources sector’s efforts in policy development, reform and approval coordination.
It also takes in the Geological Survey of Victoria and the Earth Resources Regulator. The ERR has been Victoria’s regulator of exploration, mining, quarrying, petroleum, recreational prospecting and other earth resource activities.
The Victorian Government has unveiled a new part of the recently established Resources Victoria aimed at helping the quarry industry grow.
As part of the department’s charter to help the “growth of the resources industry”, and ensure “greater transparency” and “clearer input” for all into decision-making and plan for growth, there is a new role.
Resources Victoria Approvals Coordination role will help quarries reduce approval times
for applications. This will help continue Victoria’s Big Build of infrastructure projects. “Our new regulations and approvals that will help deliver more rock, sand and gravel while ensuring the right safeguards are in place to protect the environment and communities,” Resources Minister Lily D’Ambrosio said.
“We’re ensuring Victoria has the materials it needs to meet the demand for new affordable housing and the major infrastructure projects our government is delivering.”
The new entity is expected to play a key role in:
• regulating the resources industry to effectively manage risks to the environment and community
• managing access to the State’s resources for current and future use
• policy development and regulatory reform
• regulatory approval coordination
• regional geoscientific investigations and data provision. •
Downer has forged a path into recycled materials to help make road-building materials in Tasmania.
The company’s $10.5 million asphalt plant was opened in Launceston earlier this year. It will increase the company’s Tasmanian presence, including two existing facilities.
“Our two existing asphalt manufacturing facilities in Tasmania currently produce thousands of tonnes each year that is used to build and maintain roads across the state,” Downer executive general manager –national operations George Panagiotou said.
“Now that the new plant has been commissioned, we are tripling our hourly
production rate, enabling Downer to service customers more efficiently.”
There is a growing awareness of recycled materials in Australia. Recently, Sydney councils have banded together to conduct the country’s biggest test project of recycled materials roadbase.
The program will initially use about 3,600 equivalent standard passenger car tyres, or 2,400 car and 490 truck tyres.
With an eye on this emerging market, Downer has invested significant resources.
Panagiotou says the new Downer facility brings sustainability benefits to the Tasmanian community due to its lower
carbon emission profile and improved energy efficiency.
“It’s also capable of producing road surfacing products that incorporate a high proportion of recycled products,” he said.
“This includes Downer’s Reconophalt product, which incorporates waste glass, soft plastics and up to 30 per cent reclaimed asphalt pavement.
“Using these waste products in road surfacing reduces reliance on virgin materials and delivers sustainability outcomes for the Tasmanian community.”•

The abandoned quarry training exercise was conducted as part of Talisman Sabre. An abandoned quarry has been involved in a military exercise where Australia worked with its Pacific partners, including Fiji, in battle prep.
Australian and Fijian soldiers conducted battle-prep on a dusty Star Airfield, waiting for CH-47 Chinook helicopters to insert them into an abandoned quarry.
Australian, French, American, Kiwi and Fijian soldiers worked together on the exercise as they learnt different strategies.
“We’ve learnt a great deal from our Pacific family and, in particular, the Republic of Fiji
Military Forces with their ability to integrate into local populations and the environment,” Lieutenant Colonel Ben Watson said.
“If we are to conduct operations in the region, we are doing it with them in lock-step beside us as a united force.”
The abandoned quarry training exercise was conducted as part of Talisman Sabre. The program was held across five states and territories over two weeks, featuring more than 34,000 military personnel from countries spanning Australia to Indonesia and Tonga and several other countries.
Indonesia, Fiji, France, Germany, Papua New Guinea and Tonga participated in exercise Talisman Sabre for the first time. “This was a complex series of training activities that allowed us to test our combined capabilities across sea, land, air, cyber and space operations,” Chief of Joint Operations Lieutenant General Greg Bilton said.
“These relationships are strengthened by multi-national activities like Talisman Sabre, which ensure we can work together whenever and wherever needed.”•

engineers is the first to prove that waste coffee grounds can be used to improve concrete by 30 per cent.
The data has fuelled the team’s ambitions to develop practical strategies and field trials while working with various industries.
The researchers believe the concrete industry and associated industries could be major players in this new space.
“The concrete industry has the potential to contribute significantly to increasing the recycling of organic waste such as used coffee,” Dr Shannon Kilmartin-Lynch from RMIT’s School of Engineering said.
“Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill.”
There is hope it could be a replacement for sand. Every year, 50 billion tonnes of natural sand are used in construction projects globally.
RMIT University engineers can make stronger concrete, and it might just include your morning coffee order.
The RMIT University team revealed data from their new study, which turned used coffee grounds into biochar. The process does not involve oxygen as the low-energy process converts coffee into char.
The coffee grounds are plentiful in Australia. The country generates 75 million kilograms of ground coffee waste annually – most of it goes to landfills. Globally, 10 billion kilograms of spent coffee is generated annually.
“The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change,” Lead author Dr Rajeev Roychand said.
“The inspiration for our work was to find an innovative way of using the large amounts of coffee waste in construction projects rather than going to landfills – to give coffee a ‘double shot’ at life.”
Published in the Journal of Cleaner Production, the study by RMIT
Earlier this year, the United Nations issued a warning that the world was facing a sand shortage due to its high demand in construction.
“There are critical and longlasting challenges in maintaining a sustainable supply of sand due to the finite nature of resources and the environmental impacts of sand mining,” Professor Jie Li said.
“With a circular-economy approach, we could keep organic waste out of landfill and also better preserve our natural resources like sand.” •
Quarries have often been home to fossilised discoveries from a bygone era, but a Serbian quarry has delivered a vessel of the seas.
Archaeologists have uncovered the remains of a ship in a Serbian quarry which is located near Drmno, which used to be a former Roman settlement known as Viminacium.
The finding, understood to be the second one in the last three years, is believed to be a Roman ship due to its proximity to the former settlement Viminacium.
“We may assume that this ship is Roman, but we are unsure of its exact age,” Lead archaeologist Miomir Korac told Reuters.
Viminacium was the capital of Moesia Superior, a Roman province, meaning the discovery could date back centuries to 3 A.D. or 4 A.D.
Viminacium has been heavily researched, with explorations dating back to the 1800s, but researchers believe they have yet to uncover most of the settlement.
There will now be special workers undertaken to preserve the quarry finding.
Mladen Jovicic explained to Reuters what work was required to capture the particular finding.
“Our engineer friends … will prepare a special structure that a crane will lift, and … the entire process of gradual conservation will follow,” he said.
It comes on the back of an ancient quarry that was discovered in Malta earlier this year as quarries continue to be popular sites for historical findings. •

Steve Franklin, founder of Eltirus, has heard a lot of discussion about artificial intelligence (AI) and machine learning. He explains what value it can provide, specifically in relation to leveraging intellectual property and domain knowledge.
AI is the branch of computer science that deals with software that can perform tasks that normally require human intelligence, such as reasoning, learning, decision making, natural language processing, computer vision, and more.
Common AI applications include ChatGPT and Microsoft Bing Chat to name just a few of many, many applications, some standalone and others integrated into applications we already know.
AI systems can range from simple rulebased programs to complex neural networks that can mimic the human brain.
AI is a broad term that refers to the ability of computers to perform tasks that normally require human intelligence, such as reasoning, learning, decision making, or natural language processing.
Machine learning (ML) is a subset of AI that focuses on creating models or algorithms that can learn from data and make predictions or recommendations based on the data. ML is one of the main methods for achieving AI, but not the only one. Other methods include rulebased systems, expert systems, evolutionary algorithms, or neural networks.
The answer to this depends very much on what you want to do with these tools.
While we think AI is a relatively new idea, it has been around as long as computers have existed, with the famous Turing test an early example of thinking in this area.
Proposed by Alan Turing in 1950, the Turing test involves a human judge interacting with a human and a computer through text
messages to determine which of the two is the computer with the computer passing the test if it can fool the judge into thinking that it is the human.
Parts of this article are written directly by Microsoft Bing Chat Enterprise – can you tell which parts? An interesting question is “Does the AI write a better article than me or is the optimal outcome a combination of us both writing together?”
As I mentioned earlier, we have been doing a lot of research into how we can best take advantage of AI tools within our business operations. As with any new system that we introduce, we do a lot of checking and validating before implementation.
One of the test series that I ran was about my own business, Eltirus. A simple query on the term “Eltirus” brought up a relatively straightforward, accurate description of the business that I was happy with.
On a whim, I thought I would look up the name of a colleague (who had never worked for me) that had recently moved roles within the industry. Imagine my surprise when the AI told me that that person was the founder of Eltirus (not myself) and several other pieces of data that were incorrect.
Alarmed by this, I then asked the AI to correct the data (because I had the primary source). Imagine my surprise when it wanted to argue with me about who was right.
More than anything, this exchange highlighted for me one, how conversational these systems could be (Turing test passed) and two, my great concern in terms of potentially incorrect data “out in the wild” and
I then asked the AI how it determined the accuracy of the answers it provided and how they could be corrected:
“Results are generated by applying various filters, ranking algorithms, and data sources to the user’s query. However, errors may occur in the process of producing and delivering the results, such as irrelevant, outdated, or inaccurate information. We use the following methods:
• User feedback: We can collect and analyse user feedback on the quality and relevance of the results, such as ratings, comments, or surveys. User feedback can help us identify common or specific issues that affect the user experience and satisfaction.
• Quality metrics: We can measure and monitor various quality metrics of the results, such as click-through rate, dwell time, bounce rate, or conversion rate. Quality metrics can help us evaluate the effectiveness and efficiency of the results in meeting the user’s needs and goals.
• Data validation: We can verify and update the data sources that are used to generate the results, such as web pages, databases, or APIs. Data validation can help us ensure the accuracy and freshness of the information that is presented to the user.
• Algorithm testing: We can test and optimise the filters and ranking algorithms that are used to produce the results, such as relevance, popularity, or personalisation. Algorithm testing can help us improve the precision and diversity of the results that are delivered to the user.”
In this instance, after a lot of ‘poking at it” and telling the AI it was wrong, it seemed to finally agree and remove the erroneous results. But this leads to a much bigger and broader question about how we control and edit technologies like this, particularly data that is on the internet.
I use Wikipedia for research quite a bit. I find it generally accurate, the references are cited and you can ask for/make corrections of data which is incorrect. The AI’s that I have reviewed to date do not appear to have this straightforward a functionality.
Key things to consider in relation to the use of AI in your business (and person like) are:
• Security and privacy: AI often uses advanced encryption and authentication methods to protect the data and identity of the users. However, no system is 100
per cent secure, and there is always a risk of data breaches, cyberattacks or unauthorised access. Robust security policy and protocols that are monitored and audited are vital.
• Quality and reliability: Systems rely on artificial intelligence and natural language processing to understand and generate natural and engaging responses. However, these technologies are not perfect, and sometimes they may produce errors, inaccuracies or inappropriate content. Yet again, monitoring of results is important.
The reality is that this is “uncharted waters” for many companies with attendant concerns in relation to not only the accuracy and security of data but also for the fact that an AI could potentially create an outcome that could result in psychosocial harm, security breach or other non-optimum outcome.
My testing experience was instructive – the erroneous information was one thing, but the difficulty in doing something about if definitely dented by trust of the system. My question was, why should I trust AI?
“One possible answer is that we should trust AI based on evidence and evaluation, not on blind faith or fear,” it replied. “We should trust AI when it can demonstrate its performance, accuracy, and robustness in various scenarios and contexts. We should trust AI when it can explain its decisions, actions, and outcomes in a transparent and understandable way. We should trust AI when it can respect our values, preferences, and rights, and avoid causing harm or bias.
“However, trusting AI is not a one-way street. It also requires us to be responsible and informed users of AI. We should understand the limitations and uncertainties of AI, and use it with caution and common
sense. We should monitor and evaluate the impacts and consequences of AI, and report any problems or errors. We should participate in the governance and regulation of AI, and demand accountability and oversight from its developers and providers.
“In conclusion, trusting AI is a complex and dynamic process that depends on many factors and conditions. It is not a binary choice between accepting or rejecting AI, but rather a continuous dialogue between humans and machines. By trusting AI based on evidence and evaluation, and by being responsible and informed users of AI, we can harness its potential and mitigate its risks.”
If we are looking at any data or talking to another to find out about something, we are continuously performing our own assessment of the veracity of the information – does this person/report/article know what they are talking about? We also know that some people’s opinions and viewpoints are more valuable than others and this is an integral part of our decision-making process. But what if people take the view ‘computers says’ and accept AI data at face value? How do we truly know what is correct and what is not and particularly, from what viewpoint? Are we ready to have a ‘black box’ make decisions and run our business?
Similar questions have been advanced many times in history as new technologies have arisen and that systems that we now take for granted (PLC control of plants as just one example) are now commonplace.
AI and machine learning are already making a positive impact on many different parts of our industry - we look forward to gaining greater insights into how this can increasingly be so. •

Big Enough to Trust, Small Enough to Care
Komatsu’s Smart Quarry Site has a refreshed branding but remains a modern solution to an age-old quarry problem of elevating production on-site.
It may seem simple at first glance for managers to make decisions on a quarry.
The old way had quarry managers perched on a viewing platform in the heat and harsh conditions or spending hours patrolling the site to check operations. It was hard work that was also open to human error.
This is why Komatsu developed Smart Quarry Site, previously Komatsu iSite. The platform uses real-time machine data to take the guesswork out of decision-making.
Quarry sat down with Komatsu Australia’s national business development manager, Tony Clear, to discuss how Smart Quarry Site can get the most out of machines, keep operators safe and optimise operations. The system features a suite designed to make the working day of machinery operators, site managers and quarry owners easier than ever before.
The Smart Quarry Site is a fleet management tool that is brand agnostic, able
to be fitted across a mixed fleet of machinery regardless of manufacturer.
Unlike the old days, Clear said Smart Quarry Site would enable managers to confidently make data-driven decisions rather than being stuck on a viewing platform using guesswork. On the system, they can manage the path of trucks, ensure load points are being used efficiently, and track cycles and passes to inform decisions.
“With this tool, they now have complete sight over the quarry’s operations at any time to help them make decisions,” Clear said. More than ever before, a site supervisor’s role is not just about truck performance. It is making sure each worker returns home safely.
The quarrying industry has recently been focused on improving safety across the board through safety detection and prevention.
Komatsu understood the importance of safety to quarries and implemented it into Smart Quarry Site.
Site supervisors can improve safety onsite by using the system to record pre-start checks digitally and set speed limits around the site. Smart Quarry Site can instantly alert operators, maintenance managers and supervisors of any faults while keeping a digital record showing quarrying authorities. Speed limits can be set to ensure loader operators safely perform their roles and keep their colleagues safe on-site. The intelligent system can consider loaded or unloaded machinery and inclines and declines to adapt to the required safety levels.
“It enables a driver to see when he is overspeeding, and it also notifies the site supervisor instantly, which can help address the issue on-site and keep everyone safe,” Clear said.
Aside from helping management, Smart Quarry Site is designed to work for all users. Whether site supervisors are looking
to analyse analytics or operators seek a loading guide, the fleet management system encompasses all users.
“We are trying to help those who know they need to use the technology because they will benefit from it, and they will, as well as those who want to go into the data analytics,” Clear said.
“They’re going to be able to benefit even from just using the system at its base level because of the features we have provided.”
Komatsu spoke to several machinery operators to gauge their needs in the Smart Quarry Site system. While many recognised its benefits, they wanted to be enabled to focus on operating machinery and not be burdened by doing that and data input.
This operator-led feedback enabled Komatsu to tailor the fleet management
technology to the needs of machine operators.
Smart Quarry Site lets the loader operator see the payload meter on the dashboard. This allows them to see the centre of balance on the truck, the tonnes loaded per pass to accurately load the truck the first time.
“We added these features to help the loader operator who was guessing how much to put in the truck and the centre of gravity to give them the tools to know these things exactly in real-time,” Clear said.
These factors, plus the ability to record pre-start checks digitally to increase convenience, have proved popular with clients looking to improve efficiency.
According to customer feedback, this includes remote service, which has been a solid addition to Komatsu’s aftersales service. While 82 per cent of all maintenance
requests are on the phone, the support team can remotely dial into any customer’s Smart Quarry Site platform and troubleshoot problems.
Komatsu has a strong support team with two technical advisors in each state and a customer technology advisor to support quarries. This layered approach exemplifies how Komatsu ensures customers can optimise their sites from product delivery to operation.
“We’re leaning into to support our customers whereas some clients lean away from it, sometimes they even outsource it to another company,” Clear said.
“If you compare our offering to customers to our competitors, it is a completely different experience.”•

Hydraulic hoses can be a small and often overlooked component on-site, but when they break down, they cause extensive problems.
It was a story BOA Hydraulics co-founders Simon and Greg Boakes heard too often.
From New Zealand to remote sites in Australia, quarries were being stunted by hose blowouts, which ramped up downtime and hampered productivity.
The company’s data revealed that 37 per cent of all unplanned breakdowns were due to hydraulic hoses for heavy machinery onsite.
The brothers created a high-quality solution that gave quarries more control when facing a hose failure.
Enter the BOApod, a mobile, all-terrain
Quarry spoke to TCM Quarries maintenance manager Adam Fraser about how the BOApod had transformed their working processes and maintenance plans.
TCM found that their former supplier of hydraulic hoses took much work to reach or stuck juggling several other clients’ demands. This meant the quarry endured lengthy wait times, which disrupted operations.
Fraser and the TCM Quarries management concluded the BOApod would benefit their site compared to outsourcing hose repairs.
“We could justify investing in the BOApod quite reasonably so we could have the trailer and do it ourselves,” he said.
“Many of our breakdowns were hoses, and now we’re not waiting so long; we can
because one is down. That side of hose repair is good.”
After past experiences with other suppliers, BOA’s aftersales support has impressed TCM Quarries since the two family-owned businesses collaborated.
Fraser said there was usually a day turnaround for standard fittings or two to three days for rarer fittings.
The company uses BOA’s Hydraulic Hose Management System to manage its stocks within the trailer. The trailer houses a large part cabinet with scannable barcodes, allowing TCM to reorder replacements through the BOAhub app with the touch of a button.
The speed of supply has been a boost for TCM Quarries to keep its operations ploughing ahead.
“That was a big thing for us in getting the trailer is being able to restock quickly,” he said. “Oscar always touches base to see how things are tracking.
“Everyone’s contactable, and it’s a family business like ours, so it’s good to align with that as well.”
Tallangatta Construction & Maintenance, also known as TCM Quarries, has grown from a simple truck and excavator set-up close to 30 years ago into a highly productive supplier with a fleet of CAT machinery. The business of 12 staff has established a strong reputation as a reliable supplier of materials from its own quarry and earthmoving industry.
The family-owned business has maintained a mechanically minded attitude to its growing business and workshop, which the BOApod has enhanced.
“We do all our own stuff, and we do a lot of our own welding, repairs, tyres, and now, thanks to the pod, we can do hoses,” Fraser said.
“We take it everywhere with us, even if we’re just on-site, see a hose, and undertake preventative maintenance.
“The beauty of it being a trailer is anyone could tow it; most of the guys here are mechanically minded and can make a hose.
“It is set out well, all the fittings are easily identifiable, the crimping side is straightforward, and we’ve
everything is productive.” BOA Hydraulics offers flexible finance options on the BOApod and ongoing training
the whole business.” • For
There is a convergence of power and accuracy in heavy machinery, where force and precision combine to reshape terrain in the quarrying industry. As construction and excavator needs evolve, the demand for top-tier equipment remains unchanged.
Volvo has understood the changing quarry landscape and has unveiled the Volvo EC550E excavator.
Quarry spoke to CJD Equipment’s National Product Manager for Volvo CE Hayden Grant about how the Volvo EC550E excavator can benefit quarries.
The EC550E is a 50-tonne machine and a new-size class excavator for Volvo CE.
Grant said the new 55-tonne excavator breaks through the industry norms of production by having a direct link to operating weight.
“The machine fits in between our existing 48-tonne EC480E and the 75-tonne EC750E models, offering up to 40 per cent greater production than the EC480D in typical digging applications. The EC550E is closer to the EC750E in power and so challenges the
60-65-tonne excavator class,” Grant said.
“The EC550E provides the durability you would expect from a 60-tonner. You get the power of a larger machine at a lower weight and additional fuel-saving and uptimeenhancing features.
“Volvo has set the standard for what a 55-tonne machine can accomplish.”
The EC550E, powered by the D13 Stage III engine, is designed to deliver increased performance while keeping emissions in check. With a 319kW (461hp) and a formidable digging force, this excavator can tackle the demanding tasks. Its undercarriage
primarily signifies force, while power leans towards speed. Regarding excavators, the emphasis often tilts towards force over speed, depending on the application. Nevertheless, it is essential to recognise that torque does not exist in isolation.
Grant said in the case of the EC550E, it incorporates sizable displacement pumps meticulously aligned with the engine’s capabilities. This means operators can simultaneously get high flow and fast cycle times when operating at high torque.
Volvo has provided exciting features in the EC550E.
The latest pioneering innovation from Volvo is the next-generation electro-hydraulic system with Unique Independent Metering Valve Technology (IMVT), the most advanced hydraulic system in the industry.
The IMVT system provides intelligent control with more significant variability than a traditional mechanically linked hydraulic system. This new system results in optimal controllability and efficiency when handling specific applications.
Grant said the critical feature of the entire design for the new machine revolves around the main control valve.
“This next generation electro-hydraulic system IMVT means an up to 25 per cent improvement in fuel efficiency, pump optimisation, low engine RPM,” Grant said.
“In conjunction with the electronic control valve, you can access features like creep mode and a motion priority function. These functionalities allow you to adjust the machine to match the specific operation.
“For instance, you can accelerate the boom’s movement, prioritising it over the slew function. So you can adjust the machine to suit the operation. It can then go to a different part of the quarry and start doing something else so that you can use more boom up, for example.”
Volvo can provide several services designed to assist customers in further reducing fuel costs and carbon emissions. Grant said these services can enhance the fuel-efficient performance of their machinery.
These services include fuel efficiency reports and operator training programs. Operators can optimise their site’s productivity and ultimately decrease their overall cost of ownership by utilising Volvo Site Simulations.
The EC550E provides operators with a high degree of flexibility to tailor the machine’s functions according to their preferences and the specific task. Features like boom and swing and boom and travel priority allow prioritising one function over another, enhancing adaptability.
Grant said these features reflect Volvo’s high premium on operator safety and comfort in the EC550E.
Operators can fine-tune the boom’s downward speed, which is particularly useful for precision tasks requiring precise control.
The optional comfort drive control offers an innovative alternative to traditional pedal control to streamline operations further and reduce operator fatigue. Instead, operators can steer the machine using advanced joystick rollers with an index finger grip.
In addition to these customisable features,
the technology incorporated in the machine includes boom and arm bouncing reduction. Grant said the cutting-edge technology significantly reduces machine shock, ensuring a more comfortable and productive operator experience.
Operators can quickly boost their productivity by embracing the optional on-board weighing feature, integrated into the Dig Assist Suite and driven by the 10” Volvo Co-Pilot display. Grant said the tool gives real-time insights into the bucket weight, ensuring operators move the suitable material in every pass. It maintains a comprehensive record of total tonnage per shift or day to provide robust long-term productivity data.
Quarry and open-cast mine operators can further enhance their hourly production while reducing the cost per tonne while striving to minimise the environmental footprint.
Grant said matching the size and capacity of the excavator to the hauler serves to streamline cycle times, significantly curbing idle times. With these tips, operators can use the Volvo EC550E to deliver heightened productivity, reduced fuel consumption, and lower emissions.•

The era of digital enterprise, known as Industry 4.0, is upon the quarrying industry.
Companies have invested in wireless technology and sensors because of the emergence of cloud-based technology, including sensors, instruments and autonomous devices, known as the Industrial Internet of Things (IIoT).
The interest in wireless technology comes as companies seek improvement in product margins and gain an edge in productivity.
Quarry spoke to VEGA’s product manager, Philipp Ketterer, about IIoT, Industry 4.0 and how quarries can set themselves up for success with VEGA’s new backup and restore feature.
Ketterer has seen the industry shift from not understanding data to tentatively embracing it to wanting to explore the full potential of data to shape operations and decisions.
He said digital communications is the key for companies to embrace the digital era of wireless technology.
“For Industry 4.0, there has to be fast, continuous data communication,” he said.
“The same arguments for Bluetooth in industry apply to the private use of wireless: It saves an enormous amount of wiring and time, and ultimately, costs.”
The wireless age has branched into mobile phones and apps, an increasingly important part of the quarry worker’s toolbox.
According to the company’s internal data, almost 40 per cent of all VEGA level, point level and pressure sensors are parameterised, read out and serviced via Bluetooth and the VEGA Tools app.
The VEGA Tools app also allows VEGA sensors to be directly controlled and adjusted via smartphone or tablet.
The new wireless tools, which can be used from a safe distance of up to 50m, make adjusting sensors in hazardous zones or hardto-reach measuring points considerably easier.
convenience and speed it offers quarries required by IIoT.
While the acceptance of apps and cloudbased systems benefits machine operation, it has also given rise to managing the intel of these systems safely.
Data security and storage has become a critical concern across the industry as its reliance on cloud-based technology grows.
Ketterer said previously when a level or pressure sensor was taken out of service and replaced, it took necessary sensor settings and data out too.
However, a new VEGA Tools app feature saves everything that matters, meaning settings and measured values are preserved.
Ketterer said universally accessible process data is one of the most critical prerequisites for reliable, cost-effective production.
“Sensors monitor the status and quality of the individual production steps and store important information on settings, diagnostics and the status of machines and systems,” he said.
“In turn, the users of these sensors need the certainty that they always have access to all sensor parameters and that backup solutions are available if a worstcase scenario occurs.”
Ketterer said mitigating these concerns was crucial to VEGA.
efficiency to automated processes,” he said. “Our customers can access all the data ever collected because the number of backups is not limited.”
Ketterer said VEGA’s innovative cloud solution with the backup and restore tool provides the best possible support for VEGA clients free of charge.
This is provided by the instrument DTMs and the VEGA Tools app, which quarries can conveniently access.
The backup and restore features enable users to access and reinstall available backup data.
Flexible backups and quick restores are essential for ensuring valuable process data are available for immediate reinstatement of device settings, diagnostics, or process analysis.
Ketterer said VEGA’s software tools were ideal for quarries looking to secure the complex, ever-growing data flow permanently. With the backup and restore software tool, VEGA has solved the problem many companies have, namely, keeping enough storage space available for ever larger quantities of data. All parameters can be saved securely in the VEGA cloud at regular intervals. By using trusted software tools to handle data storage and safety, quarries will be wellplaced to thrive in Industry 4.0. •

As quarries increasingly move towards technology-driven operations, data storage and safety are becoming an emerging concern for operations.Quarry operators are increasingly using technology to make intelligent decisions.
Bonfiglioli is helping quarries minimise costs and reduce risks with its specially-built drives.
Digital technologies are becoming a big part of the resources industry. But according to the 2021 Boston Consulting Digital Acceleration Index, the industry is estimated to be 30–40 per cent less mature than similar sectors.
The report found that accelerating digital transformation would allow the resources industry could boost throughput, simplify processes, lower costs, improve metal recovery and yield, and reduce supply chain complexity.
To support the quarrying and mining industry in its effort to digitise, gearbox manufacturer Bonfiglioli has developed Industrial Internet of Things (IIoT) solutions to reduce maintenance related downtime.
Martin Broglia, managing director at Bonfiglioli Australia and New Zealand, said the company’s sensorised units produce data, which enables optimised maintenance scheduling, residual lifetime monitoring and health status checks.
“These solutions give the customer full control of a critical component like the gear
units, minimising the risk of production losses as well as operating and maintenance costs,” he said.
Having been active in the resources sector for more than 60 years, Bonfiglioli now offers one of the largest ranges of planetary, parallel shaft helical and bevel helical drives.
The group designs, manufactures and distributes gearmotors, drive systems, planetary gearboxes, and inverters.
Its portfolio includes solutions for crushing, sedimentation, filtering, and material handling.
Because quarries often experience extreme environmental conditions, Bonfiglioli ensures its equipment can handle temperature fluctuations, sandstorms, salty humidity.
“These are among the factors taken into consideration in the design stage of our machinery, resulting in the development of resilient solutions that meet the demands of the sector,” Broglia said.
This type of product offering is complemented by the company’s local assembly capabilities and its after-sales support and service, helping to reduce downtime and bolster customer profitability.
“Our local engineering and service teams offer 24–7 service, travelling directly to mine sites when required,” he said.
“With a worldwide network of branches, distributors and service companies, we can extend technical support to customers around the world.”
The flotation machine is a key component in sedimentation systems.
Big tanks in a series, containing mineral solution and reagents, separate the pure element from the mineral. The mixture is stirred by a specially designed impeller, powered by a gearbox placed on top of the machine.
“It’s critical that the process is not contaminated. This can be guaranteed by our gearbox Drywell solution,” Broglia said.
“The last output bearing, which is reinforced to withstand the high radial and axial loads of the moving impeller, is closed and sealed
Fast fact:
Established in 1956, Bonfiglioli operates worldwide with 21 branches, 14 production facilities, a network of 550 distributors and about 3770 employees.
within a greased chamber. This prevents oil leaks, making the gearbox drip-proof.”
A complex, compact piping system connected to the gearbox housing at strategic points ensures perfect lubrication of the bearings and gears. A double filter installed in the circuit and monitored by sensors ensures the lubricating oil remains free of impurities.
The gearbox drives a mechanical pump, which ensures greater reliability than an electric solution. For improved mixing, pressurised air is fed into the tank through the impeller shaft to the base of the tank via specially connected piping fixed to the top of the gearbox and fanged to the impeller shaft.
A complex system of seals, labyrinths and pressure sensors facilitates the pipe
connection and prevents the entry of air into the gearbox, protecting all components affected by the pressurised flow from wear.
“When installed at an altitude of 4000m, there is no need for an external cooling system, making the solution simpler,” Broglia said.
“This reduces the risk of failure and the maintenance burden.”
Broglia said reliable performance of Bonfiglioli’s solutions is fundamental to the relationship the company has built with customers.
“Our experience, coupled with close collaboration with leading OEMs and customers, enable us to develop customised solutions that meet the requirements of a range of applications,” he said.
“Here, we are able to help our customers achieve the highest possible plant productivity.” •

888 Crushing and Screening Equipment is backed by three directors with more than 30 years of experience in the industry.Conundrum Holdings is at a crossroads as a relentless campaign is waged against the quarry despite the ever-increasing demand for materials.
Demand for quarry resources has rarely been higher. However, instead of being celebrated as a pivotal part of a critical sector for Victoria, a family-owned business has been battling a council-led campaign.
Quarry spoke to Ron Kerr, managing director at Conundrum Holdings, about how it has been battling to correct the record.
According to details provided by Conundrum Holdings, the Mitchell Shire Council has refused to accept the outcome of several state planning decisions, including multiple versions of the long-term strategic plan allowing for a quarry.
These include the C106 Planning Panel, in which the precinct structure plan (PSP) is to
“explicitly include resource extraction from Work Authority 1473”, and the C157 Planning Panel, in which the PSP is to “identify quarry at 175 Northern Highway, Wallan”.
“I am disappointed with how the council continues to misrepresent this story to the community,” Kerr said.
Conundrum Holdings, a family-owned business based in regional Victoria, is currently awaiting approval for a permit for a new quarry located between Beveridge and Wallan to Melbourne’s north.
Kerr – himself a fellow of the IQA – has been creating jobs and opportunities for the many businesses that rely on a competitive and reliable supply of quarry materials and premix concrete.
Northern Quarries at Epping, Victoria, is Conundrum’s base, extracting basalt from Melbourne’s newer volcanics at a shallow flow resource.
“We could see the life of Northern Quarries coming to an end; we’ve been there for more than 30 years,” Kerr said.
Conundrum was privileged to be approached by a local landowner in 2004 to apply for a quarry as far north as possible within the same basalt fields in the Wallan region.
Opening a greenfield quarry like the North Central Quarry site is a familiar experience for Conundrum Holdings. The new project was approached with the same methodical and compliant strategies that have culminated in securing vital community resources.
In the mid-1990s, it took just nine months to get approval to open the greenfield Northern Quarries, only 27km from Melbourne’s CBD. Conundrum commenced the application process for this short-term new site, the proposed North Central Quarry.
Quarry resources, where possible, benefit the State by being as close as possible to their market, minimising energy use, friction, and wear of vehicles. North Central Quarry’s resource offers Melbourne’s north just that.
The site is ideally situated 43km from the CBD, within 530 metres of a nationally recognised road network for heavy transport, minimising impact on the community by avoiding the need to pass residential housing. These conditions have seen this site included within the state’s Extractive Industry Interest Areas since the early 1990s.
“We all need to minimise our carbon footprint, and therefore, a quarry must be as close as practical to its end use – particularly within Victoria’s fastest-growing growth corridor,” Kerr said.
Earth Resources Regulation, the Victorian quarry regulator, issued the application its own identification, WA1473, in 2011, mapping it onto the State’s publicly available register, GeoVic, and granted statutory endorsement in 2015 to demonstrate the application was possible.
While commencing drilling in 2006 with a site free of any suggestions for future urbanisation, the area was gradually absorbed into Melbourne’s northern growth corridor.
In 2010, a small portion of the site was earmarked for future residential development and in 2012, further land to the north was included in the corridor.
Kerr said quarrying remained a legitimate land use and consistent with State policy.
“I feel the local council believes that there is a greater opportunity to have this area used for residential land. There is a genuine lack of understanding and appreciation for our industry and the benefits it brings the community,” Kerr said.
“Quarries have multiple uses; it’s not just a single-time land use, and it normally runs in line with the growth and development of the community. Unfortunately, the appreciation for these resources over time has been lost to the developer’s interest.”
Almost 20 years later, Conundrum continues to wait for a decision on the application, which is currently with the Planning Minister.
“At the current rate, the approval process will take longer than the projected working life of this quarry,” Kerr said.
The North Central Review reports the Mitchell Shire Council had spent more than $1.3 million of rate payer’s money, as substantiated by freedom of information requests.
Mitchell Shire Council chief executive Brett Luxford told the North Central Review the
bulk of the expenditure was spent on lawyers, marketing and consultants.
“While we are disappointed that we have had to expend significant resources on this issue, the council stands by its decision to do everything in its power to protect our community and their future,” he told the North Central Review
“The bulk of the expenditure in this matter relates to the unfortunate situation council found itself in having to engage lawyers and experts to defend a scenario we should never have been put in.”
Per their media release, Conundrum Holdings said the number of anti-quarry group members was a “fractionally small amount” of the local community with 271 email addresses on the council’s “Stop the Quarry” campaign.
“Council could have acted as a responsible authority and assisted the community’s understanding that the traffic, dust and noise matters are within acceptable limits
as identified by the Mitchell Shire Council own experts, in conclave with independent experts – rather than propagating unwarranted fear throughout our community,” Kerr said.
Luxford stated publicly in the North Central Review that the council had complied with all directions.
“Throughout this process, the council has complied with all Freedom of Information requirements.”
“We are not anti-quarry; we just cannot accept a quarry in the middle of a master-planned community of more than 100,000 residents,” Luxford told the North Central Review.
Conundrum Holdings has refuted that the council complied with the requirements smoothly. According to the release, it took 18 months to receive the information and only occurred after review by the Office of the Victorian Information Commissioner and a legal challenge by the council.
Luxford has publicly stated that the council’s main concern was the quarry was not identified in the Beveridge Northwest PSP.
“When the Victorian Government exhibited the Beveridge Northwest Precinct Structure Plan for public feedback in 2019, the quarry was not identified as part of the Future Urban Structure,” he told the Northern Central Review
“We have a community of residents who bought properties not knowing there would be a quarry in the middle of their neighbourhood.”
Per their media release, Conundrum Holdings refuted the claim, stating the area has been an Extractive Industry Interest Area and the quarry was always shown in the various drafts of the Precinct Structure Plan.
According to Conundrum, the quarry is not located within a residential neighbourhood where residents will be subject to adverse amenities. This is supported by the Victorian Civil and Administrative Tribunal (VCAT) hearing over the issue, where the VCAT panel member stated: “I do not consider that the proposal may result in material detriment to them [properties outside of 1km] because of any direct amenity impact or potential visual impacts.”
Rather, its western neighbour since 2006 has been a government agency’s waste water irrigation facility.
The demand for Victoria’s quarry materials is expected to double between 2015 and 2050 and is already tracking at levels higher than this as recently reported by DEECA.
“North Central Quarry is a very high-quality source in a good strategic location, and it is not replaceable,” Kerr said.
“My concern remains that there may be a decision in our favour one day, however, with conditions such that our proposal is rendered financially unviable to open. I can’t say there’s an answer because clearly, we don’t have an answer - we will just have to continue to push our case respectfully,” he said.
To draw the community closer to the industry, Conundrum Holdings recently published a series of books highlighting the support for the North Central Quarry.
Volume One is called ‘Delivering Choice and Opportunity’, documenting North Central Quarry’s journey to date, including a selection of support submissions for the quarry from almost 400 different people.
Volume Two is called ‘From Quarry to Community’, a pictorial book illustrating the art of quarrying and its benefits to the state. It uses photos and quotations from various submissions to build public awareness and pride within the quarrying industry. Volume Two is available from Conundrum Holdings, which hopes these publications will help set a new benchmark for how the industry perceives itself and how the quarrying story and history are told to outsiders.
“Without a doubt, you could say that as a family business, we’ve had a lot of people work with us and know us,” Kerr said. Our industry is a great industry; it supports our society and builds communities.”
Kerr has advocated for the importance of the quarry industry to be seen as an essential primary industry for the community, for Victoria’s growth and for local jobs. He is concerned for the industry’s future as it faces significant challenges with new quarry approvals, costly compliance requirements and increasingly complex regulations and conditions for quarries.
“We are witnessing the gradual demise of family-operated quarry businesses throughout our state,” Kerr said.
“In hindsight, I wish the basalt was somewhere else, but the rock is where the rock is, the market is where the market is, and the road network is where the network is.”•

The Women in Industry Awards recognise outstanding women leaders from across Australia’s industrials sector.
Quarrying’s role in modern Australia has been examined at length. Its importance as the backbone of Australia’s infrastructure projects, housing developments and roads cannot be understated.
However, Queensland research highlighted its role in ancient Australia with Indigenous Australia, the world’s oldest living culture.
Research and excavation have shown that Indigenous Australians created a vast network of quarries along “Australia’s Silk Road”. Researchers from Queensland describe the area as encompassing the Gulf of Carpentaria to the Flinders Ranges in South Australia.
Michael Westaway from the University of Queensland worked with a group of researchers and Indigenous people, including traditional owners Shawnee Gorringe and George Gorringe, to Mithakia.
“(The channel country) connected large numbers of Aboriginal groups throughout that arid interior area on the eastern margins of the Simpson Desert,” Westaway told The Guardian.
“People interact across the continent, exchanging ideas, trading objects and items and ceremonies and songs.
“We don’t know how far and wide they were being distributed, but they were an important element.”
Mithika country is close to Betoota, of social media acclaim, and Birdsville, of the Big Red Bash concert.
The Mithika people worked in a relatively sophisticated system across an area larger than Belgium in a “channel system” or as Westaway termed it, “Australia’s Silk Road”.
The researchers worked together across Southwestern Queensland in 2021 and uncovered many remnants of the Indigenous past in the era.
The findings indicated the Mithakia people mined stone for tools and may have had permanent settlements where they traded goods and lived.
A key finding was the Mithika people’s sandstone quarrying, which was traded and used for tools like grinding stones to make bread.
The final numbers are telling: 179 quarry sites across 33,800 sq km, with some estimated to be more than 2000 years old.
There was one site that the researchers described as “pretty special” to the Guardian which encompassed close to 25,000 individual quarry pits.
It is thought to be one of the broadest quarrying networks of its time in Australia. Doug Williams, who conducted his PhD on this research, has, according to Westaway, found thousands of these quarry pits, considered among the largest of their kind.
“I thought we’d stumbled across this urban settlement, but it turned out to be not what I thought it was,” Westaway told the ABC.
“They were actually these infield quarry pits from these massive quarry sites as well as stone huts and villages.
“Then we started to find wooden structures, some which date back to the 1700s, and they’re still standing, and they’re quite robust and the oldest houses in Australia.”
The research came on the back of Bruce Pascoe’s Dark Emu, a controversial novel that dissuaded the idea of Indigenous Australians as hunter-gatherers.
In his award-winning book, Pascoe claimed there was enough evidence to consider Indigenous Australians as agriculturalists.
as a research project for the book. sieves are used, and in the fireplaces, we’ve been able to identify seeds.
“We’re identifying new methods to investigate the archon-botanical remains of these sites, and a huge amount of stuff is turning up.”
The common belief is now that the Indigenous people had quite a level of sophistication in their networks and builds. The group found accounts from native police who stumbled upon villages of more than 100 people in 1871.
The sheer scope of the mining operations has impressed politicians, academics, and archeologists alike.
The archaeological evidence could allow wider Australia to broaden its understanding of how some of the earliest First Nations people lived.
The University of Queensland Anthropology Museum held an exhibition on the findings.
It included several recovered artefacts under the Kirrenderri, Heart of the Channel Country, co-curated by Tracey Hough,
a director of the Mithaka Aboriginal Corporation, and Shawnee Gorringe.
“They were engaging in the buying and selling of all these remarkable goods,” Westway told the ABC.
“(This research) is giving us new insights … it’s not the sort of thing that fits comfortably with huntergatherers and not fitting comfortably with agriculturalists.
“It’s got us scratching our head a bit as we try to understand the systems better.”
Craig Crawford, Queensland’s Aboriginal and Torres Strait Islander partnerships minister, flew over Mithika country after the research came to light in 2022.
“The mining operations were extensive –you could even see ones where there had been exploratory digs,” told The Guardian.
“Anyone that wants to question the sophistication of the networks that First Australians had – I think these challenges it to its core.”
After extensive research, Westway had a new appreciation of quarrying in Indigenous Australia.
He hopes that in the future, they can conduct more excavation to understand the nature of these villages better.
“The scale of them is just mind-blowing,” Westaway told The Guardian. •
Darren Toth, director of ToThink Engineering, explains the benefits of vee-belt drive systems on vibrating screens and some common (and avoidable) issues associated with them.
Although there are many different methods of driving machines, vee-belt drive systems are quite common on many different types of equipment in quarries and recycling fixed plants. More specifically, on vibrating screens, the vee-belt setup is particularly common for several reasons.
Vee-belt drives are efficient and compact for the amount of power they are capable of transmitting. When it comes to vibrating screens this compactness, combined with the need for an offset between motor and screen shaft, makes cat-walk level the ideal place mount the motor.
Vee-belts are smooth and quiet, and slip is negligible. They cope very well in dusty environments because there is nowhere for the dust to collect (or become trapped) and cause problems. While vee-belt drives are not suitable for extremely high speed or very low speed applications, vibrating screens appear to be within an ideal speed range for this type of drive system. Vee-belt drives are also a relatively low-cost arrangement.
The drive motor on some vibrating screens is mounted on a pivoting motor base. That is, a base that allows movement of the motor but with a mechanical resistance provided by some sort of flexible/spring device. This spring is typically a rotating rubber-element or a steel coil spring. The benefit of using a pivoting motor base it that vee belt tension can be maintained over a much greater range of movement of the screen shaft (relative to the motor). This significantly reduces the peak tensions in the belts (particularly during start up and shut down) and also helps to keep the belt seated in the pulley groove if/when the belts become slack.
While it isn’t always necessary to install a pivoting motor base on a screen, a properly set up base will significantly increase the life of the vee belts as well as other components such
belts and the need for their replacement.
Poorly designed, installed and/or maintained systems can be quite problematic. Here are a couple of details to be aware of that may help avoid making some common mistakes.
Many vibrating screens with vee-belt drives are supplied, by the original equipment manufacturer (OEM), with deep groove pulleys (both the screen pulley and the motor pulley). That is, the grooves are deeper than those of a standard specification pulley and so the veebelts sit well inside the major (outer) diameter of the pulley. This greatly reduces the chances of throwing a belt as there needs to be a lot more movement before a belt can be slack enough to flick off.
We have had customers who have had their non-OEM suppliers replace pulleys based on the vee-belt size and the major (outer) diameter of the pulley but assumed the pulley was a standard pulley. When the worn deep-groove pulley was unknowingly replaced by a standard groove pulley, not only was it far more likely to ‘throw’ a belt (as the grooves were no longer deep) but the pitch circle diameter of the pulley was significantly altered and, as a result, the operating speed of the screen changed. In the case of changing a motor pulley, this error would lead to an increase in rotational speed of the screen. It would have the opposite effect on the speed if the same mistake was made
motion screen (with a vee-belt drive) is typically supplied (by the OEM) with an eccentricity (radial offset) in the screen pulley. That is, the centre of the outer rim of the pulley is not in the same location as the centre of the shaft. The purpose of this is to negate (or cancel) the motion of the screen in the direction along the line between centre of motor pulley and centre of screen pulley. In simple terms, the intent is to minimise or eliminate any tugging action (on the vee-belts) caused by the vibration (throw) of the screen. The direction of this offset, relative to the screen counterweights, is critical. The message here is to be aware of this because, again, we have had customers who have been supplied replacement pulleys without this offset and it has caused premature wear or failure of drive components.
Now on to pivoting motor bases. When incorporated into a vee-belt drive system, there are some simple guidelines that if actioned help maximise the effectiveness and service life of the motor base.
Firstly, wherever possible, orientate and position the motor base so that the weight of the motor contributes to the belt tension rather than reducing it. That is, set up the base with the motor mounting plate offset from the centre of the pivot of the base and mount the base and motor so that the motor is on the opposite side of the pivot from the screen pulley. In
setting the motor base up this way, the amount of tensioning required by loading up the rubber rotating element (or spring) is minimised due to the weight of the motor adding to the belt tension.
Secondly, aim to achieve as close to a 90-degree angle as practicable (see diagram) between the line joining the pulley centres and the line between the motor shaft and the motor base pivot. This means that any rotation at the pivot, caused by movement of the screen pulley is minimised. As a result, the peak stresses in the rubber rotating element (or coil spring) are reduced and the service life of the motor base is improved.
For some readers this information may help explain past (or current) challenges. The intent here is to raise awareness of some lesserknown details and to highlight the importance of sourcing the correct components from companies with the appropriate technical knowhow. •

A great day was had by all at the ninth annual 2023 Quarries and Concrete Health & Safety Conference in Newcastle in early August.
Bringing together more than 190 delegates, sponsors, exhibitors and speakers, the day explored the principles of high reliability organisational theory, incident investigation, electrical safety, and vehicle interactions, with a focus on psychosocial hazards, emerging issues, compliance and regulatory requirements.
A big thank you must go to all members of the conference committee for their time
and dedication behind the scenes, and a special shout out to our guest speakers, sponsors and exhibitors who make events like this a great success.
The annual IQA NSW Women in Quarrying lunch was held near Wollongong at Bulli Tops in mid-August, and it was a great day with wonderful turnout of more than 70 people.
The panel of industry-leading professionals provided their personal views when discussing growth, opportunity and challenges regarding the employment
of women in quarrying . The speakers shared inspirational stories and insights to forging a pathway for others in their respective careers.
The day celebrated women in industry while also acknowledging issues of diversity.
It was a platform for people throughout the industry to connect with others who have proven themselves as opportunity creators.
With the guidance of facilitator Dr Gillian Vogl, Women in Quarrying aims to use this event as qualitative research and provide actionable outcomes for future
The Victoria branch Winter Quarry Night and Annual General Meeting (AGM) was held at the Stolberg in the Melbourne suburb of Preston on Thursday August 24.
The event started with a welcome from recently appointed IQA chief executive officer Clare Murray, who spoke about the organisation’s strategic plan for the next three years. Victoria branch chair Michael Oppedisano then moved onto AGM proceedings, providing an overview of the last financial year with a run-down of events held and sponsors.
Oppedisano thanked retiring committee members, including deputy chair/secretary and IQA Fellow Chris Prowse, who served as a committee member for 28 years. The new committee for the 2023–24 financial year was then elected.
The guest presenter on the night was Rebecca McKernan, commercial manager at Repurpose It. McKernan’s presentation explored how Repurpose It built Australia’s first wash plant, allowing valuable resources to be diverted from landfill and reducing the need for virgin materials. She also discussed the challenges in introducing recycled materials into a typically non-recycled industry, as well as how products are made and tested.
The Stolberg provided a great setting for a wonderful night of networking and formalities. Thanks to all IQA members, non-members and associates who attended.
The Sydney Harbour Bridge has been an imposing landmark on the city’s skyline for decades.
The landmark celebrated its 100th anniversary since construction started on the integral road and transport system, which doubles as one of Australia’s famous attractions.
While the project, also known as the ‘Iron Lung’, provided critical jobs during the Great Depression, it also birthed it created Granite Town near the south coast town of Moruya.
The town’s quarry supplied all the granite to the bridge’s pylons as part of the construction.
The excavation from the town was a significant part of why the Sydney Harbour Bridge was able to open on March 19, 1932.
NSW Premier Chris Minns said Moruya played a pivotal role in Sydney’s famous bridge.
“It boosted the steelmaking industry of Newcastle, while Moruya played a pivotal role in the construction through the supply of granite for the pylons,” he said.
Back during the age of construction, Moruya was a hive of different nationalities tasked with operating the Granite Town. The town featured nearly 250 employees from 13 nationalities, mainly Italians, Scotsmen, and Australians.
The Captain Cook statue and the Anzac Memorial in the state’s capital also use Moruya granite.
Its reputation for high-quality gravel and tram lines to the local wharf made it an easy call for British engineering company Dorman Long, who won the construction contract.
There was just a tiny problem in Granite Town. There needed to be more infrastructure.
Enterprising residents and immigrants built several facilities, including a swimming pool built by the quarry workers, according to the Moruya Examiner in 1927.
Historians believe the town featured 72 cottages, a post office, and a school at its peak. This development contrasted with most of Australia.
After the Wall Street crash in 1929, many in metropolitan Australia were battling to make ends meet while the Granite Town provided stable work and income during these dark years.
The local quarry tasked its workers with precisely shaping granite blocks across the chain from the site to the local wharf. The result was close to 18,000 cubic metres or 173,000 granite blocks.
According to several reports, it was split away from the quarry face by drilling holes
into the rock with hammer drills driven by compressed air. Gunpowder and blasting powder were pressed into the holes using an air drill. An alarm would sound, and then the blast would be fired.
“Like all major projects, construction of the Sydney Harbour Bridge came at a cost. It cost 14 lives of workers on site and two at Granite Town in Moruya, and it came at the cost of many homes that made way for the build,” NSW Roads Minister John Graham said.
“One hundred years on from this event, we appreciate the Bridge as a Sydney icon, a place at the heart of many celebrations – but also a vitally important piece of road and transport infrastructure that the system cannot do without.
Christine Greig-Adams, greatgranddaughter of the Moruya quarry manager John Gilmore, said stories of Moruya’s impact on the project became family folklore.
“My granny went to the opening of the Sydney Harbour Bridge, but she always said that the team at the Moruya quarry never got enough recognition for the extraordinary work that they did,” she told About Regional.
“The entire project was planned and managed in Moruya.
“Each block was labelled, numbered, laid out in order, and shipped to Sydney, ready to be assembled.
“Not one stone was rejected.”•
