OFHAVEOTHERCOIN.SIDEHEALTH“MONITORINGISONEOFTHEONTHESIDE,WEREDUCTIONRISKS.” It’s been a successful month for the industry with new appointments at Sandvik and Boral, and new product launches such as Holcim’s recycled clinker (page 10). It seems every day the industry gets one step closer to its sustainability goals. In line with this, we can see that key industry players are also taking steps towards achieving equality and diversity. For example, Metso Outotec has invested $3.1 million to correct genderrelated pay gaps and companies like Weir Group are highlighting the importance of allyship and changing biases (page 8). Weir Pride Alliance Affinity Group steering committee member Yesenia Meraz-Torres shared an excellent analogy:“Sexual orientation, gender identity and gender expression are part of someone’s identity – just like the colour of one’s skin. Some aspects of our identities are visible, while others are not. “This is part of why I choose to be an ally. To help everyone feel safe, comfortable, and respected whatever their identity. I encourage others to do the same,” she said. I hope to see many more businesses joining the fight for equality, equity and inclusion.Moving onto the rest of the issue, this month we have taken a closer look a different type of safety: occupational health and safety. Quarry spoke to Heart of Australia head of operations and business development Ewan Wylie about the importance health surveillance for quarry and mining workers (page 20). Wylie pointed out that aside from obvious instantaneous risks like working with machinery, other hazards can take years to show up. Therefore, monitoring worker health and identifying hazards is of upmost importance.Ontheother side, we have reduction of risks. In line with this, Kinder mechanical engineer Jack Cain highlighted the importance of controlling dust exposure – whether that is coal or silica dust. He shared various tips on what to watch out for and ways to reduce exposure to dust (page 28). In this issue we will also look at equipment in action. On page 22 we look at how Kobelco’s new SK380XD excavator is helping Clarence Sands Quarry improve operations. And on page 26 you can read about how Kleemann MSS802 Screen is doing wonders at Butlers Yarwun Quarries. Quarry also had the chance to speak with Puma Energy about its company values, products and it is investing in the environment for a more sustainable future.Wealso want to congratulate our cover advertiser Terex Washing Systems as it celebrates over 50 years of operations. You can read more about its humble beginnings on page 30. The IQA has had a busy month and therefore this month’s issue features a bigger IQA news section to reflect that.

he Institute of Quarrying Australia’s (IQA) strategic plan vision, values, and strategic priorities remain clearly in focus, and we are now in position to grow and transform after building a strong foundation following two and a half years in a relative defensive mode due to the pandemic. We are in a sound financial position, and we have progressed several important transformational programs that will help deliver our strategic priorities i.e., maximise outcomes for the industry through education and sustainable practice, increase our relevance and a high performing and sustainable organisation. The strategic priorities underpin our transformational programmes that were identified following an extensive survey of our members and the wider quarrying sector.Thesurvey addressed several key areas, such as what type of training and education the quarrying sector requires, the type of networking that members value, the flexibility and ease of access to relevant and/or mandatory training and education our members and their employers need. We asked our members to provide input into what company requirements, specific operator skill and professional development requirements such as leadership, management, and supervisory skills, would compel members to attend events to fulfil their obligation to their employers. We also asked members and the wider construction materials sector about what national standardisation of practices they’d like to see to support small and medium sized quarrying organisations, and equally as important, how we support the sectors regulators and their requirements. The underlying principle for our transformation programmes is that we cannot stand still, and we must deliver increased value for our members, sponsors, and the construction materials sector partners if we want to protect our history and be around for the future. A number of these programmes are multi-year and will require support and commitment from successive boards and our members. After the IQA’s AIQEF and Audit committees rigorous review and support for the recommendations, at the June 2022 meeting, the IQA Board resolved to support the recommendations from CEO Kylie Fahey, and the resources required to deliver these key strategic transformational imperatives. Funding is now approved in the FY22/23 budget. Exciting times ahead. We have briefed branch chairs and we will need ongoing input and support from all branches to ensure the various projects succeed. You will be hearing and reading about the details in the coming months as the projects take shape. I encourage you to where possible get involved, your input is valued and would be very much appreciated. Afterall, this is your Institute, and we want the same thing, not to stand still, to greatly improve member value and implement a pathway for a sustainable future for many, many years to come. As I near the end of my three-year term as president, I look forward to witnessing and experiencing how these transformational programmes increase our relevance for our members and the wider quarrying sector. As always, I hope you and your families are staying healthy and no doubt we are all looking forward to welcoming the warmer Spring weather ahead.
The Institute of AustraliaQuarrying quarry.com.au The IQA’s Strategic Plan 2020 to 2025 embodies the following vision, values and strategic priorities: Vision: Educating and connecting the extractive and associated industries. • A safe and sustainable environment.

Meraz-Torres said she recently heard a great analogy that that helped her understand the difference between choice and identity: “Sexual orientation, gender identity and gender expression are part of someone’s identity – just like the colour of one’s skin. Some aspects of our identities are visible, while others are not,” she explained. “This is part of why I choose to be an ally. To help everyone feel safe, comfortable, and respected whatever their identity. I encourage others to do theWeirsame.”Pride Alliance Affinity Group aims to play in helping achieve inclusion, diversity, and equity priorities at Weir Group.

“We can be the voice of our colleagues and advocates when they aren’t in the room,” Meraz-Torres said. “Regardless of where we are in our ally journey, being supportive, accepting and open to all will help make Weir an even better place to work.”Likewise, ensuring that people feel like they belong will also help them to do their best for their company. To achieve this there needs to be a sense of urgency, and businesses need to actively “help move the needle in the right direction faster,” Meraz-Torres said. “We need to be open-minded around conversations about the LGBTQ+ community... and keep learning how to be a better ally.”
Weir Group believes that LGBTQIA+ allies play a pivotal role in ensuring its workplace is inclusive for everyone. Affinity groups help identify gaps in knowledge or understanding that might be due to unconscious bias or lack of insight of the matters at hand, Weir Pride Alliance Affinity Group steering committee member Yesenia Meraz-Torres (she/her) explained in a blogpost.Therefore, allies play a critical role in helping address these gaps or biases.

Liebherr’s new Betomix and Mobilmix modular design mixing plant series will replace several predecessor series. The new mixing plant series can be combined using prefabricated modules. Individual modules can be planned and manufactured independently of each other and combined with other modules. Customers will benefit from more freedom when configuring plants, shorter delivery times, faster assembly, and increased parts availability. Improvements to the drive will also reduce current consumption by up to 30 per cent and increase weighing accuracy – this means that up to 7.5 kg of cement can be saved per cubic metre of concrete.Likewise, hybrid mixing processes and shorter mixing times are easy to implement, avoiding power peaks. The modules pre-wired and fully assembled at Liebherr. They feature a folding concept and plug connections so they can be quickly and efficiently assembled and put into operation at the construction site. Depending on the customer’s requirements and use, mixer systems can be installed in the same basic system.

A research team from the Universitat Politècnica de València (UPV), part of the Institute of Concrete Science and Technology (ICITECH), is studying various samples of volcanic ash for the manufacture of cement and concrete. The samples studied are from the Cumbre Vieja volcano, on the island of La Palma.Sofar, the results obtained by the UPV team has shown volcanic ashes to be sufficiently reactive to be applied in the manufacture of cements with additions (type II) or pozzolanic cements (type IV). The ashes show a good homogeneity, considering the different origins of the samplesPhysical,collected.chemical, mineralogical and mechanical tests have found that the volcanic ashes meet the regulatory requirements for use as a mineral addition in“Thesecement.volcanic ashes should be considered as natural waste, as it is a material that has occupied or is occupying spaces that correspond to infrastructures, industries, roads, farmland and housing,” GIQUIMA-ICITECH team member María Victoria Borrachero said. “To recover part of the social and economic activity, and to preserve the environment, it is necessary to recover the use of the several million tonnes of this ash that may be available,” GIQUIMAICITECH team member Lourdes Soriano said.“And, in view of the first results of our study, cement-based materials are a great alternative for the management of this large volume of waste material,” he added.Themain objective of the GIQUIMAICITECH team at the Universitat Politècnica de València is to give value to this ash in the field of civil engineering, by means of collection, management, conditioning and application through a cement or construction company.
CEMENT AND CONCRETE MADE FROM VOLCANIC ASH?
“We are now analysing projects in which the results of the research can be applied,” GIQUIMA-ICITECH team member José Monzó said. Next, the team will focus on evaluating the behaviour of these cements in the long term and on optimising the dosage in the composition of the new cements with ashes from Cumbre Vieja. •
HOLCIM LAUNCHES RECYCLED CLINKER
“This breakthrough shows what is possible when you combine Holcim’s unique expertise in recycling with its leading position in cement production,” Holcim Innovation Center director Edelio Bermejo said.
“Developing 100 per cent recycled clinker takes us one step further in our quest for circular construction to decarbonise the built environment.” Holcim is accelerating its contribution to circular construction as part of its net-zero journey to decarbonise the built environment. To support this, Holcim has recycled 54 million tons of materials across its global operations in 2021 and plans to double that rate to 100 million tons byTo2030.build new from old, Holcim is stepping up the recycling of construction and demolition waste into new building materials, with the goal of reaching 10 million tons by 2025.

Vik Bansal has been appointed Boral chief executive officer and managing director, effective Monday 5 December 2022. Bansal will replace current Boral chief executive Zlatko Todorcevski, who will remain in the role until the transition is complete. Bansal has more than 30 years of leadership experience in managing complex industrial organisations. He has demonstrated the ability to guide organisations through significant growth, transition, and improvement.
“This includes providing essential construction materials such as sand, stone, gravel, cement and concrete for the building of new hospitals,” CCAA chief executive Ken Slattery said. Such materials – which are sourced from local quarries, concrete plants, and cement facilities – will be used for roads and transport infrastructure, schools and social housing, Slattery pointed out. However, demand for additional social and economic infrastructure underlines the need for policy reforms across key sectors delivering these projects.
“The State’s Government continued focus on infrastructure is welcome, though highlights the need for improvements with quarry approvals, regulatory efficiency, supply chains, energy costs and skills and labour,” CCAA state director, Queensland Aaron Johnstone said. “Like other sectors, our industry is currently facing enormous supply chain challenges – despite the increased materials’ demand from population growth and new infrastructure,” he said. •

Currently, mineral reserves being sold and consumed at a faster rate than they are being replaced, which has been an ongoing issue for “well over ten years,” the MPA said. Likewise, “it can typically take 10 to 15 years to identify and prove resources, secure land and rights, prepare and submit planning applications, and for these to be determined and permissions issued,” the MPA said. Due to this, the implications of the 2042 deadline will start to become significant in around five years’ time, it asserted.
• Highly skilled team of employee and contractors
In response to this, the Mineral Products Association (MPA) released a briefing stressing the importance of maintaining productive capacity up to and beyond 2042. It asserted that while some operations will have exhausted their reserves by then, many sites may still contain commercially viable reserves, and may still be producing essential minerals. Making the most of these reserves is vital due to a shortage of mineral reserves.
• Modern fleet of Crusher, Screens & Excavators
“Given the essential nature of mineral supply to the delivery of national ambitions for infrastructure and housing, whilst increasing our resilience to climate change and delivering the roadmap to net-zero, it is vital that the issue of transitioning to 2042 and beyond whilst replenishing supply is addressed now,” the MPA said. 847 079

The MPA will explore feasible legal routes that can be taken to continue to work resources where appropriate.

“It is important that we continue to learn from safety incidents and improve workplace hazard controls until we no longer have any preventable workplace injuries.”
“Heart of Australia’s mission is to reduce the burden of distance when it comes to healthcare services for those in these communities,” Heart of Australia head of operations Ewan Wylie told Quarry. “Heart of Australia aims to reduce the inequality of accessible specialist services and improve patient outcomes for those living in rural and remote communities.”
SAVING LIVES WITH HEART OF AUSTRALIA
HEART OF AUSTRALIA To ensure the health of those working in mining and quarrying, Heart of Australia launched its newest mobile clinic Heart 5 in February 2022. It is a joint initiative with the Queensland Government to provide increased accessibility to lung checks for current and former mine and quarry workers in rural and remote Queensland.“Heart5,our latest mobile health clinic, was funded by Resource Safety Health Queensland (RSHQ) to support the screening and early identification of mine dust lung diseases (MDLD),” Wylie said. He explained that “given the resource industry in Queensland typically operates in rural and remote areas, Heart of Australia was excited by the opportunity to expand the services we were already delivering. “We wanted to build a mobile service that would not only improve accessibility to high quality screening services, but also the equipment and specialists needed to investigate abnormal results in a timely manner.”Themobile medical imaging clinic includes X-ray and CT scanner equipment to assist in the screening and early detection of mine dust lung diseases, such as black lung and silicosis.“Heart 5 has been set up as a “one-stopshop” and is able to deliver chest x-rays, spirometry and physical examinations but is also able to complete the further investigations of HRCT, laboratory lung function and respiratory specialist consults typically needed to confirm or exclude a diagnosis of MDLD,” Wylie“Theexplained.truckisa RSHQ approved spirometry and radiology clinic, and the service is operated by RSHQ approved doctors.
Heart of Australia is a mobile medical program delivering specialist services to rural and remote communities in Queensland.Itslatesttruck to be launched, Heart 5, was on display at the recent IQA Quarrying & Mining Safety & Health Conference in Townsville, Qld where Heart of Australia head of operations Ewan Wylie presented the truck’s healthcare capabilities and CT scanning technology.
Heart of Australia was founded by cardiologist Dr Rolf Gomes in 2014 with the launch of Heart 1 – a mobile health clinic.
HEALTH RISKS WITHIN MINING AND QUARRYING Wylie explained that “mining and quarrying activities have many associated health risks such as human interactions with large plant and equipment, noise, vibration, heat, uneven and wet ground, and dust to name a few. “Most of the hazards on a mine or quarry site pose an immediate safety risk, but for dust, the consequences of excessive exposure are unlikely to be evident until many years after the exposure/s occurred.” Therefore, it is important to monitor respiratory health consistently and identify hazards before they cause harm. “Respiratory health surveillance is extremely important for mine and quarry workers as we need to diagnose as early as possible those affected by respiratory hazards in the workplace so that any further harm can be minimised,” Wylie said. “Early detection has been proven to improve health outcomes,” he noted. “It is also important that we identify when workplace controls may have failed or been

“Additionally, to the standard examination, we are also able to provide audiometry, visual acuity, bloods and urinalysis, stress tests and functional assessments through the truck.”
Since its launch, Heart 5 has “travelled over 22,000kms and delivered over 950 respiratory health examinations for coal and mineral mine workers, silica exposed workers, and former mine and quarry workers,” Wylie said. “Heart 5 has screened former/retired mine and quarry workers in Gladstone, Biloela, Rockhampton, Mackay, Collinsville, Moranbah, Cairns, and Mount Isa,” he added.
By providing workers with access to health care on-site, Heart 5 minimises the travel and time off work required to complete respiratory health surveillance. “The battery technology we have designed and built in Queensland to power the CT scanner means with Heart 5, we can do a CT parked on a mine site – and that is a world first,” Heart of Australia founder Dr Rolf Gomes said in a press release. “Heart 5 breaks down the barriers of distance, so if you do have a lung disease, we can find it early and quickly,” he added. Heart 5 also features the world’s first battery powered CT Scanner, meaning that diagnostics can happen in an efficient and timely manner if required. “By being a one-stop-shop, we are able to complete all the required investigations in one appointment,” Wylie said. “As well as an efficient examination process, our patient management system helps sites manage on-boarding their workforce data as well as meet reporting obligations,” he continued.“Ourprograms meet all privacy and confidentiality requirements for managing workers health data and are designed to enable learnings from the data we collect so that we can support safer workplaces today and into the future.”

The SK380XD delivers an average fuel consumption of under 20 L/hr in typical The SK380XD has thicker triple plated reinforcement in all key areas of mechanical stress.
KOBELCO SK380XD:
22 Quarry August 2022 EXCAVATORS
The SK380XD excavator is built for extreme durability and is engineered to operate in the harshest conditions, making it ideal for quarry operations.
MAXIMUM EFFICIENCY AND DURABILITY
As with any quarry operation, excavators often wait idle between dump truck rotations. Therefore, Clarence Sands Quarry required an excavator that could offer fuel economy as well as reliability. “(For) sitting idle and waiting between dump trucks, Kobelco’s fuel economy was really appealing,” Urus said. “Hence why it made a bit of sense to go for the machine that had the better fuel economy waiting for dump trucks in between to load.”
The Kobelco SK380XD excavator is the heaviest in its class at 37,700 kg and promises unbeatable fuel efficiency, delivering industry leading productivity to the most demanding worksites.
Australian Civil Management Group director Michael Urus spoke to Quarry about the new excavators. According to Urus, the quarry initially purchased one Kobelco SK350 excavator, which “did the first four months in production without missing a beat. “Hence, we went and bought two more.” The initial machine was traded in for the SK380XD. Likewise, the quarry was increasing production, therefore the decision was made to invest in two SK380XD excavators to keep up with“Thedemand.SK350 got up to about two and a half thousand hours and the new SK380XD was more spec’d for a quarry,” Urus said. “The arm was slightly beefier, and Kobelco had made some changes to the machine that looked very interesting and more useful for the application, hence why we went for the heavier specification new model that had come out.”
The SK380XD is purpose-built, featuring a robust machine body and substantial additional reinforcements to all key areas of stress and wear across the boom, arm, underbody, and undercarriage. It also has thicker triple plated reinforcement in all key areas of mechanical stress, for unbeatable durability and longevity. This ensures that the SK380XD can last in the harshest of applications. Likewise, the arm foot boss shape has also been modified and improved to efficiently distribute loading, delivering increased strength for demanding tasks, like rock ripping and quarry mineral extraction. A specially designed full-length rock guard is installed on the inside of the dipper arm on top of additional steel plating. The Kobelco features a bucket breakout force of 244 kN and arm tearout force of 180 kN, as well as a powerful slew torque of 120 kN which ensures maximum productivity levels.
THE SK380XD IN ACTION It was the SK380XD’s innovative technology, Japanese quality and reliability and fuel efficiency that made it an attractive choice for production at Australian Civil Management Group’s Clarence Sands Quarry in the Blue Mountains, NSW. Currently, the quarry operates two Kobelco SK380XD excavators for production work. “Clarence Sands is in its third year of operation,” Sydney Trucks & Machinery (STM) sales manager Mark Morris said. “The SK380XDLC-10 was the obvious choice when they decided to replace their 2020 SK350LC-10. The key attributers to the purchase decision included: no breakdowns, nil downtime, fuel savings, fast dig cycle times, and reduced cost of ownership.”
FUEL EFFICIENCY AND RELIABILITY
“The SK380XDLC-10 excavator is ideal for quarry applications, with its strengthened extreme duty boom and dipper,” STM area manager, north Sydney Peter Moore added. “Being purpose built for handling repeated large capacity loads, adding extra durability to a long-life machine. The undercarriage was also built up with extra strengthening ribs, more track guides, and highly durable chains, also boosting durability in severe working conditions,” he said.
Australian heavy digging conditions.
“Kobelco excavators have long held a reputation of power, speed, and fast cycle times,” Moore said. All this, with excellent fuel efficiency, Kobelco’s matching of modern engines to compliment excellent hydraulic performance which results in less fuel burned while still retaining class leading performance.”

According to Urus, in addition to fuel economy, the Kobelco excavators are very reliable machines. “It’s certainly been a very reliable machine. We’ve never had to contact anybody for after service. I’m sure they’ve got very good service backup (but we’ve) never had to contact them,” Urus said. “It’s doing a great job doing production,” he added.Australian Civil Management Group has a strong relationship with Caterpillar, which provides a large portion of its equipment but after a business partner recommended Kobelco, they thought they would invest.
The boom to arm hydraulic regeneration system improves fuel efficiency while reducing cycle times and boosting productivity.TheSK380XD has three work modes which allows the operator to select the best mode for the job at hand: heavy, standard and an ECO-mode which automatically optimises digging efficiency, delivering a 24 per cent reduction in fuel consumption.
Likewise, “the SK380XD’s mechanicals, developed from previous models, have had a long history of minimum downtime, excellent reliability, and economic serviceability. This leads to lower costs per hour for the owners.”
The partner “pointed out the benefits of using a Kobelco and we thought we’d give it a crack with them,” said Urus. “We are certainly impressed with how the Kobelco has performed,” he added.

OLI VIBRATORS
ToThink Engineering specifically uses Oli Vibrator motors on its own “ToThink” brand of machines built in Australia. With Oli Vibrators, ToThink Engineering has a “reliable, available, and broad range of vibrator motors to engineer into our own equipment as well as into existing machines that others have manufactured,” Toth said. “We are confident to use Oli products and so are our customers.” More specifically, Oli Vibrators has been supplying ToThink Engineering with industrial vibrator motors predominately from its range of electric vibrating motors (MVE). “The motors supplied have ranged from 300 kg force, which were used to aid bulk material flow in product bins, up to 22000 kg force, used on large vibrating screens,” Toth said. “Some motors have been supplied to replace existing motors on a like-for-like basis where replacement has taken place without modification to any part of the equipment,” he explained.“Othershave been supplied with other key components (e.g., drive beams, motor mounting frames, etc.) necessary to replace other makes of vibrator motors that have a different mounting interface but where Oli Vibrators has been the preferred replacement.”OliVibrators is ToThink Engineering’s “preferred supplier of vibrator motors because they provide a high-quality, reasonably priced product range that is well supported by the Oli Australia team and well stocked in Oli’s Melbourne warehouse,” Toth said. “For these reasons we, and our customers, feel like we are getting great value and can be confident whenever we put Oli products intoForservice.”example, “the two biggest highlights (of our relationship with Oli Vibrators) have involved four of the largest motors we have sold so far,” Toth noted. “One pair of MVE22000/1 vibrator motors were supplied with one of our large dewatering screens to a sand quarry in Eastern Victoria,” he recalled.
SUPPORT WHEN YOU NEED IT Toth believes that the partnership ToThink Engineering has with Oli Vibrators works well because it extends well beyond great value, quality products.
ToThink Engineering is a Melbourne based business providing equipment such as screens and feeders, engineered solutions and various hardware items to the quarry, recycling and mining industries.Duetothe demands of the industries it services, ToThink requires “high quality, reliable suppliers in order to achieve the best long-term results for our customers,” ToThink Engineering director Darren Toth explained. For ToThink, Oli Vibrators fits the bill. In fact, Oli Vibrators has been ToThink Engineering’s choice of supplier since it first began operating.“Soonafter ToThink Engineering (Australia) began in 2016, Oli and ToThink realised the benefit that a close, long-term relationship would bring to both companies,” Toth said. “This relationship continues to grow along with a steady increase in the volume of business between the two businesses.”
When looking for high-quality, reliable suppliers, ToThink Engineering doesn’t need to look further than Oli Vibrators.
“In addition to supplying the Oli motors for this project we also redesigned the frame onto which the vibrator motors are mounted and were able to improve the performance of the screen as well as its reliability,” continued Toth.“Ayear has now passed, and the machine continues to run reliably,” he added.
GOES ABOVE AND BEYOND
“Not only do the Oli Australia team provide us with fantastic backup and support but we are also able to liaise with members of the Oli team in Italy,” he said. Toth pointed out that “as a mechanical engineer and equipment designer I need to also be able to engage with technical people,
“The other large pair of motors were MVE19500/1 vibrator motors that replaced motors of a different make (on a heavyduty screen manufactured by one of our competitors) that were failing approximately every 12 weeks for a number of years.”
The MVE22000/1 Oli vibrator motor is the largest motor ToThink Engineering has used to date.

“We don’t just sell, we engineer,” he stated.
Likewise, Oli Vibrators’ Australia presence ensures reliability and continues to build trust with ToThink Engineering and its customers. Toth explained that “there are many vibrator motors in service on equipment across Australia for which there is no replacement on the ground within Australia.” Therefore, “when purchasing vibrating equipment that uses vibrator motors it is strongly advised that you investigate where a replacement motor would come from should a failure occur, how long it would take to get to you and what it would cost to do so.”

HOW BUTLERS YARWUN QUARRIES GROWS PRODUCTION
Butlers Yarwun Quarries has added its delivery of the Kleemann MSS 802 EVO mobile scalping screen plant to the growing list of highlights of its four-year relationship with Wirtgen.
Butlers Yarwun Quarries is a familyowned business that has been operational since 1986. “We produce road bases, aggregates for concrete and asphalt, etc., for heavy industry,” Butlers Yarwun Quarries SSE/ manager John Sherburd told Quarry Helping Butlers Yarwun Quarries achieve its targets is equipment supplier Wirtgen Group. “What we get with them is reliable equipment,” Sherburd said. Butlers Yarwun Quarries has purchased three Wirtgen screens in the last two years, including the Kleemann Mobiscreen MSC 953 EVO triple deck screening plant and a Kleemann MS 21 Z mobile double-deck scalping screen plant. The third screen, and the most recent addition to the line-up, is the Kleemann MSS 802 EVO mobile scalping screen plant. “We needed to buy an additional screen for a contract that we have so we can double production and meet some pretty significant targets at the same time,” Sherburd said. Butlers Yarwun Quarries chose the MSS 802 EVO for several reasons. Firstly, Butlers Yarwun Quarries felt that in comparisons with the alternatives from other companies, the MSS 802 EVO was a lot better suited to its needs. “(We) went through advantages and disadvantages of a couple of competitors with what we needed and the MSS 802 EVO came out on top,” Sherburd said. Likewise, “being the been the newest one that Wirtgen made; I was pretty keen (to get it).“Plus, we’ve got two others here, so you’ve got continuity of parts,” he added. Sherburd was initially drawn to the MSS 802 EVO as it boasted a new design which offered higher quality build and improved safety.“Quality is good with the new (MSS 802 EVO),” Sherburd said.
26 Quarry August 2022 SCREENING
The new design of the MSS 802 EVO also means that it was stronger, more powerful, and productive – which is exactly what Butlers Yarwun Quarries needed to achieve its targets.
“It helped us achieve the targets because it’s a new machine; it’s a lot stronger than the older ones,” Sherburd said. “Things run better because of the configuration of the pumps, with the conveyors. (There’s) less downtime with blockages.
“They’ve improved the quality; the safety aspects are a lot different as“So,well.for me, in the new machine, it would be, I think 50 per cent better than the old ones,” Sherburd noted.
“It’s been significant in helping us over the last couple of months here,” he explained. In particular, Sherburd praised the MSS 802 EVO its enhanced safety that offers. “The main reason that we went for (theMSS 802 EVO) was due to a new safety aspect on that screen that the other screens don’t have.” This “makes for ease of changing screens, accessibility for working on it,” he said. For example, the MSS 802 EVO features good quality walkways for people to ensure workers’ safety when doing maintenance work, Sherburd noted. “Also, the screen is better than the older ones in the fact that each conveyor has a standard line pump system for it,” he continued. This means that “they have more power, don’t get blocked as much and you can put more weight over them. “So, that’s one of the reasons we went with that one,” Sherburd said. “Actually, we purposely blocked it to see how easy it is to unblock than the old ones,” Sherburd added. With the MSS 802 EVO, “you can drop down flat, and the conveyor becomes like a walkway as well, so it’s a lot easier to get round, a lot easier to change safely,” Sherburd explained. Another major plus for Butlers Yarwun Quarries is the availability of the“Availabilityscreen. was a big thing. And (the MSS 802 EVO) was readily available. There was no waiting time on it,” Sherburd said. He explained that other companies often have a six to eight month wait for However,equipment.withWirtgen, “we were able to get it and get it to work straight away. (This) was the main advantage of it,” Sherburd said. When considering a new purchase, a business’s customer service plays a key role. “The relationship we’ve got there with the people was (another) main one to consider,” Sherburd said. Sherburd sees Butlers Yarwun Quarries relationship with Wirtgen continuing.“Therelationship I’ve developed with certain parts of Wirtgen has been really good over the last four years. I would buy another,” he said.Infact, “we’re talking about other equipment at the moment,” SherburdCurrently,added.Sherburd is most impressed with the delivery of the MSS 802 EVO and considers it a highlight of Butlers Yarwun Quarries’ relationship with Wirtgen. “It’s a lot different than what the old ones were. It was a highlight getting the MSS 802 EVO and seeing it running,” he said.

Dust fineness is measured based on particulate matter (PM) size. Fine particles (PM2.5) are smaller than 2.5 μm (1 μm = 0.001mm), coarse particles (PM10) are sized between 2.5 μm and 10 μm and “larger than PM10” is for all particles with a diameter of 10 μm or greater. The occupational exposure limits of respirable dust and respirable crystalline silica is 3.0mg/m3 and 0.05mg/m3, respectively across an eight-hour shift. This includes 10mg/m3 of inhalable dust. It is important exposure to dust is maintained within stated exposure standards to mitigate any risks.
Despite the numerous risks associated with dust particles, there are certainly ways reduce exposure.“Thankfully, when it comes to mitigating exposure to dust, modern conveyor solutions provide quite the arsenal,” Cain said. “Take the transfer, for example, likely the dustiest place on any conveyor.”
SEEKING A SOLUTION
According to Cain, skirting is one of the most effective methods of keeping material from spilling out of transfer the moment it touches the“Ideallybelt. you would want skirts that provide some sort of contact seal, but when the diameter of dust is measured in microns, even a 1mm gap is enough for millions of particles to escape,” he said. “So, a proper seal needs this belt contact to be effective, and contact means wear so a skirt needs a way to combat wear,” Cain explained. “A self-adjusting skirt, that maintains full effectiveness for its entire lifecycle without the need for direct maintenance is incredibly costeffective.“These self-adjusting skirts are typically quite soft to allow for them to conform to the belt unhindered.”Cainexplained that this softness leaves the skirts vulnerable to the harshness of the material stream, which can cause damage as it flows by. “So, typically a hard internal skirt that stops just short of the belt is used to keep the material at bay, while the soft skirt picks up the slack and completes the contact seal in relative safety,” he said.
28 Quarry August 2022 DUST
DUST: THE GREAT ESCAPE
Cain recommends contactless external skirts “if the wear and tear of contact systems rubs you the wrong way”. “While they do tend to hit a higher price point in the short term, these marvellous devices tend to make up for it with their almost nonexistent maintenance costs,” he pointed out.
“Using their unique geometry to manipulate the power of airflow, a continuous suction effect is created to keep dust in.
“These contactless skirts still require the support of an internal hard skirt to make sure they don’t clog up with the larger product, but their overall effectiveness is impressive. “Of course, with all this skirting it’s imperative that your belt profile is well supported to maintain consistency and prevent gaps, even more so with contactless skirting which requires a very particular spacing for the proper suction flow to be possible,” Cain explained.According to Cain, how you support your belt will depend on the conditions of your transfer point.“Systems that experience low impact from a Contactless external skirt and static rail system.
Kinder mechanical engineer Jack Cain discusses processes to control the exposure of dust in quarrying operations. The dust that comes from mineral production, crushing or even from handling aggregates requires management. Luckily there are a number of measures that business can take to reduce dust level exposure to workers and the environment.Accordingto Kinder mechanical engineer Jack Cain, the formation of this dust is not entirely unwelcome. “In some cases, the dust is the intended product,” he said. “So efforts to negate it are rarely required, nor are they entirely plausible. “Therefore, the more auspicious approach is to control the spread of this by-product by removing any possible avenues of emission into the environment and exposure to workers..”Dusttends to gather in transfer points. If it is discharged into open air, can end up in stockpiles rather than in sealed chutes or hoppers.Andifthe product is exposed to environmental factors such as wind, it can disperse the top layers. “In any areas where vibration is common, where this jolting movement can bounce the material around, it can cause unsettled particles to wander off the conveyor,” Cain said.“The movement of the belt starting, stopping or even just when travelling at high speeds can be all that’s needed to disturb the top layers of material.”
Eliminating dust from becoming airborne through higher level controls is critical.

“These systems all tend to utilise low frictions rails (typically < 0.3 static coefficient of friction) on the wings to create a consistent surface for the belt to move across. “However, this is still an increase in friction over most rollers.
Mitigating dust cannot be solved solely at the transfer and needs to be managed across the rest of the “Comparedconveyor.tothe transfer point, the run of the belt typically has far less structure to encase the product and protect it from the open elements,” Cain said. This requires special equipment adapted to such“Beltconstraints.coversare physical barriers that attach to the stringers and almost completely enclose the belt, preventing the influence of wind and trapping dust that is disturbed by vibration and belt movement,” Cain said. “Belt covers typically are made from rigid materials such as steel or reinforced plastics, Water sprays can also be used as an effective dust-suppression tool, though they are not without their drawbacks.
“The resultant water saturation is undesirable for a lot of products and the wastewater must be delt with, limiting their desirability for numerous applications,” Cain said. Likewise, extraction fans can be effective when run across the belt length, but filters must be replaced to maintain effectiveness.
“Unlike the belt run, discharge points can usually be encased in structure with dust curtains to prevent any dust spreading, but when material is being discharged into open space, an extendable loading chute is more appropriate as it can be used to guide the material down to the stockpile without excessive dust being thrown during the fall,”
Cain said. PREVENTION IS KEY “Controlling and containing dust is simple and affordable with an abundance of modern products,” Cain said. Cain recommends operators evaluate their conveyor and determine any locations that are a source of dust, so a solution can be applied.“Operators who would prefer evaluations confirmed or would prefer professional input on the severity of issues can seek conveyor inspections from the numerous available conveyor solutions providers,” Cain concluded.
“While these rails typically quite resistant to abrasion, they will eventually require replacement as well,” Cain said.

In this time, it has continued to commit time and resources to developing and investing in R&D to bring the latest technologies and systems to the wet processing world. All this hard work is demonstrated by the strength and depth TWS has across its product portfolio of end-to-end washing solutions. This includes its AquaClear water management solutions and GreenLine engineered recycling solutions. In fact, these solutions have a history that dates back to the 1960’s – starting with the Finlay and Powerscreen product lines. The mid-60’s saw the development of the very first washing plants and the following decade saw the launch of the MK1 and MK11 Rinser range. It wasn’t long before Powerscreen and Finlay began to realise the crucial need and potential opening in the market. They knew that the natural sand and gravel supply would soon be exhausted, especially with stricter building and construction specifications being written for aggregate usage.Astechnology started to advance in the late 70’s, the sand saver de-waterers soon phased out and were replaced by more sophisticated and modernised screw recovery de-waterers, later to be called the Trident range. In the 90’s Finlay and Powerscreen both set up dedicated washing departments. But by the noughties the demand for washing was expansive that TWS was established as the sole provider of washing solutions within Terex in 2012. Having started from humble beginnings, TWS continues build on its existing legacy and continues to refine its craft in the wet processing industry. It is thanks to all the learnings, continuous TWS washing plant. TWS AquaClear water treatment solution.

The German cement manufacturer installed the M-Sens 3 directly on the conveyor belt with a shuttle to continuously monitor the moisture content of the sand. The work required to take samples and check moisture levels in the laboratory is no longer necessary, saving time and costs. On a conveyor belt system, the M-Sens 3 can measure moisture of the solids and allow operators to react in real-time if material is too humid or dry, helping prevent plugging of aggregates.Additionally, when mounted at a bin’s outlet, the sensor can take advantage of the constant bulk density and almost unchanging measuring field for monitoring residual moisture.Thishelps operators stop material that is too damp from reaching the next production level. The system itself has been designed for easy installation and calibration. All an operator needs to do to calibrate the sensor is press a button and enter the referenced moisture content. Measured fluctuations in bulk density and temperature are automatically compensated by an internal filter function.

Manually checking moisture in the laboratory can be a slow process. However, installing a sensor for continuous moisture measurement can be just the solution. To produce cement, a German manufacturer required sand taken either from internal storage facilities or delivered by ship. It found that the material had a much higher moisture level when it was transferred across the water. The company previously checked the material moisture manually in the laboratory, but this was a slow process. It was therefore looking for a continuous moisture monitoring system for the sand transportation.Tosolvethisissue, the company installed SWR Engineering’s M-Sens 3, a microwave sensor specifically designed for continuous moisture measurement of solids during batching.Thesensor monitors product flow for its moisture content and temperature, which can be used to detect the efficiency of the product stream.Dusts, powders, granulate and other bulk solids are constantly analysed to identify process failures, such as a defective screw or material clogging. The M-Sens 3 sensor functionality is based on precise high-frequency measurement and direct digitalisation of measured values, which results in a high resolution. The use of up to three sensors, connected to a MSE 300 evaluation unit, means induced measurement inaccuracies caused by the materials inhomogeneity can be reduced. The influence of bulk density variations, which normally exist over the whole measurement zone, are also reduced by an internal filter function.Thesensor does this by monitoring the material’s surface and capillary moisture, which influences the specific conductive capacity of a material. This can then be compared to a averaged bulk density to determine if investigation is required.Intheevent of a material process failure or caking around the sensor, an alarm can be sounded to ensure the validity of the measurements is always high. Temperature variations are also compensated automatically by the sensor. The temperature measurement is calibrated in-factory and doesn’t need any additional operation from use.
M-Sens 3 is specifically designed for continuous moisture measurement of solids during batching.

VEGA’S SIMPLE RADAR FORMULA FOR BETTER PROCESSES
34 Quarry August 2022 SENSORS
Ushering in a new level era with the VEGAPULS 6X.
What sounds like an obvious question has led VEGA to create much more than just an even better sensor. When using the new VEGAPULS 6X, it’s not just the sensor that counts, but what can be achieved with it in the application: Simply better processes. The search for a suitable radar sensor traditionally begins with the question, which frequency would work best for this application?Thisisfollowed by thoughts about the properties of the media and how it could influence the measurement, as well as the specific installation environment. Furthermore, the temperature range or the presence of aggressive chemicals may give cause for concern. Will a standard process fitting be sufficient, or would special materials that meet the highest requirements be the right choice, if only because the user is not completely sure and wants to be on the safe side? And what else should be considered if the sensor is to measure great distances or be exposed to wind and weather all year round? These and countless other questions make one thing clear: with such a wide choice, you also must make the right choice. The areas of application are becoming more multi-faceted and processes more complex. Therefore, the buyer needs a good understanding and overview of what the market has to offer. It takes the right know-how, experience, and time to avoid making costly bad investments and get a reliable measuring system.
A NEW CERTAINTY: ‘ONE FOR EVERYTHING’ Choosing an instrument is usually a laborious process and often involves a lot of questions and research. VEGA wants to turn this process inside out with its new VEGAPULS 6X, one sensor for all applications. “Ultimately, it’s not the sensor that counts, but what the users can achieve with it in their individual applications,” VEGA international product manager Florian Burgert said. “Just knowing that they’ve chosen the best possible instrument solution, and that they’ll reach their goal faster with it, makes a big difference in their everyday operations.”
Selecting the right frequency or determining the (dielectric constant) DK value of the medium are no longer obstacles; the new configurator asks for the type of application and then quickly determines which sensor version is required. The entire procedure consists of just a few mouse clicks. That said, an advisory discussion with a VEGA radar specialist is still a good alternative to the configurator. Either way, the result is simplicity for users and a measurement solution that delivers results independently of the media properties, process conditions, vessel shapes and internal installations.
The actual task of level sensors is to help users and make it easier for them to monitor their industrial processes. They often make processes more controllable and efficient, but even if they are basically easy to use, the process of selecting the right one for an application can still be Skowaisadifficult.sums up in two words the strategy VEGA is pursuing with VEGAPULS 6X: “maximum simplification.” “Until now, there were many different sensors that could be used for an application, but today, with VEGAPULS 6X, there is one sensor for all applications,” he said. Even setup and commissioning has been reduced to a minimum, requiring just a few clicks and the input of basic data. “Our customers can even order a sensor that has been factory-calibrated, customerspecific down to the last detail, that only has to be installed and connected. It doesn’t get any easier than that,” Skowaisa said.
VEGAPULS 6X also offers decisive technical innovations.Acomprehensive safety concept means functional safety is guaranteed, the company said, as it conforms with all the requirements of safety integrity level (SIL). The certified sensor has strong SIL characteristics and provides the necessary operational safety to minimise risks in safety-related applications. Another increasingly important focus is cybersecurity. In this regard the VEGAPULS 6X conforms to IEC 61511, which fulfils the strictest requirements for security of system access and communication control. It thus guarantees comprehensive process security, right through to the control system. An important third aspect of the sensor’s safety features is its self-diagnosis system, which continuously monitors the function of the sensor and recognises if it has been impaired in any way, thus contributing significantly to higher plant availability and sensorCentralperformance.totheseimportant features is a new, second-generation radar chip directly from VEGA.Because there was no chip available on the market that would have met all requirements, the research and development team set to work to design one itself. “The result pretty much consolidates our entire radar experience from three decades,” VEGA product manager Jürgen Skowaisa said. “In its scope and functionality, the chip is unique in the whole world.”
RADAR MADE FOR PEOPLE With VEGAPULS 6X, VEGA has rounded out its radar measurement technology with four important innovations: More safety and self-diagnosis, new radar chip technology, new application possibilities, and simpler adjustment.“Furthermore, our technology has reached such a high level today that reliable function is no longer the issue,” Skowaisa said. “The only risk now is choosing the wrong sensor.”

FOUR-STAGE ALL-ROUND PROTECTION
The chip is especially characterised by its low energy consumption, high sensitivity, scalable architecture and universal applicability. The radar antenna system and the chip are directly connected to each other, without any cable, for maximum performance. Beside the technical highlights, the VEGA radar team addressed questions that, from the very beginning, went far beyond product design.Whatwill be the long-term impact of this technology on the people who use it? How can their work be simplified? What future goals of industry can be realised with the new technology?Bycarefully considering the users and the process conditions of their applications, other points came into focus. These included the challenges in using measuring instruments, such as complicated adjustment procedures, the constant pressure to increase efficiency, and time constraints in general.
VEGAPULS 6X: one sensor for all applications.
Thanks to the new approach with VEGAPULS 6X, VEGA now provides the tools to get right sensor version for the application in 99 per cent of all cases, while keeping experienced application engineers on standby to help with the special, more difficult applications. “In the future, the user will no longer have to worry about the technology, frequency or instrument version – the measurement will simply work,” Skowaisa said. • Visit vega.com/radar for more information.

COMMITMENT TO SUSTAINABILITY
Puma is the largest bitumen shipowner in the world by carrying capacity of 342.5k dead weight tonnes.
Another product to be added to the Puma Bitumen line up is the OLEXOBIT S45RLV crumb rubber modified seal binder manufactured from Australian sourced waste tyres.The S45R-LV is the successor to the company’s sprayed seal binder OLEXOBIT S45R, also made from waste tyre rubber. According to Puma, every tonne of OLEXOBIT S45R repurposes the equivalent of 23 passenger vehicle tyres. The S45R-LV crumb rubber offers a low viscosity alternative to regular crumb rubber sprayed seal binders. As such, the S45R-LV reduces the need for cutter, meaning that less hydrocarbons end up in the environment, further helping companies to address sustainability goals. It can be used in extreme stress seal applications and can be applied to alleviate the reflection of cracks on existing cracked surfaces where the cracks are active. “Puma’s S45R-LV offers much improved ease of handling and application benefits, whilst providing the same trusted field performance as conventional S45R,” Prinsloo said. She explained that one of the main application benefits of S45R LV over conventional S45R is that is it easier to spray, providing improved circulation and faster loading of sprayers, helping to improve overall operational efficiency.

Shell Lubricants believes that the success of a quarrying, mining or construction business depends on its ability to ensure equipment runs efficiently andWhetherreliably.the project involves earthmoving, transporting loads, levelling, compacting, or digging, a business relies on its equipment and accompanying lubricated components. Equipment breakdowns can severely compromise project schedules and prevent a company from earning revenue. Shell understands that businesses, whether its construction, quarrying or mining, are constantly striving to meet deadlines and lower operating costs. According to the 2019 Shell Global Construction Industry Report, 43 per cent of construction companies said they often experience breakdowns because of ineffective lubrication – and 72 per cent agreed that their maintenance teams needed moreExcavationtraining.and construction equipment can be tough and operate in a range of harsh environments. Therefore, it’s important to use the right combination of lubricants to get the most out of your engines, transmissions, hydraulic systems, and greased components. Using the right combination of lubricants together can improve vehicle and equipment productivity.Likewise,lubricant costs can be as little as 1-2 per cent of total maintenance costs whilst optimising lubricant use across all operations can save 30 per cent of operating costs, according to Shell’s Industry Report.

The project overview was well received by all and the effort from Rusty and Ashbrook was greatlySpecialappreciated.mention:A long-standing committee member, Wayne Kelly, was also recognised for his service to the Illawarra sub-branch and greater quarrying arena. Kelly is looking at easing off after 25 years and, on behalf of the IQA, previous committees and members thank him for the effort.
A (literal) boatload of brave people gathered on the southern break wall area where Rusty provided detail on the holistic precinct. Despite the gusty wind trying to push the boat to Auckland, the boat held fast. It was noted that the project and walls looked swish and the well aligned armour group also spotted two distinct rock colours (particularly on the northern seawall end). On quizzing Rusty about the contrast, he simply stated that they had basically exhausted the local and greater surrounding area rock supply, so granite from Moruya was approved for use to ensure all stakeholders came to a mutually agreed finish point. To escape the high winds and continue the project overview, the group convened for dinner and networking at Club Windang.
The principal contractor was a wellestablished local outfit, Coastwide Civil (CWC), and the event was hosted by the company’s director Craig ‘Rusty’ Rodgers.
Rusty presented some pictorial evidence of the project progression, and his presentation was very detailed and highly regarded by everyone. To also put a spin on the blast side of the extraction, Rusty introduced Paul Ashbrook from Precision Drill and Blast. areas, discussing reworking the blasting ‘bang’ and where and why particular ‘detonators and specialised explosives’ were chosen.Generally, we tend to think of blasting as lifting and moving the raw feed away from the face as an example, but Ashbrook explained that this situation required a more refined ‘popping’ approach so the respective diggers could then load out the material.

Co-hosted by the IQA, CCAA, and in collaboration with the state regulator, the NSW conference is a one-day interactive program addressing current safety and health issues relevant to the quarrying and mining industries.
• Townsville, in conjunction with the RSHQ A fantastic array of speakers presented on critical areas of health and safety. Both conferences were opened by Kate du Preez, Queensland’s Commissioner for RSHQ. The upcoming NSW Safety and Health Conference will be held on Wednesday 19 October at the West HQ Rooty Hill in Western Sydney.
The weather put on another beautiful far north Queensland day for this year’s IQA Cairns Golf Day on Friday 3 June. With a great mix of people across all levels of the quarrying industry, there were plenty of laughs and a great opportunity for those in this very busy industry to take a few well-deserved hours out for some fun and networking.

The group toured the WesTrac Tamworth facility, including the workshop and warehouse.Delegates then climbed aboard a minibus bound for the Graymont Attunga Limestone quarry, with sub-branch chairman Chris Brown behind the wheel. CAT 980-wheel loader was waiting at Attunga. WesTrac’s Paul Andronicus gave a live demonstration, and the group also had and the opportunity to try the new machine. Graymont then explained some of the key differences between a lime and limestone operation and that of a typical hard rock quarry.Wethen treated to a walk through the lime kilns, where limestone is converted to quicklime by heating the rock up to approximately 900°C. These visits were followed up with a networking dinner, where it was great to connect with new and old industry acquaintances. WesTrac’s Gavin Handley presented to the group on some of the latest innovations to CAT equipment.

What’s your current role and what does this involve? I am currently working to develop and implement an online system to assist in management of sites including environmental compliance, health and safety, employee and contractor management, plant and equipment management and site document management and auditing. How long have been in the industry? I’ve been in the industry for nearly 14 years, where I have worked in various roles from admin assistant, environmental scientist and now data systems manager. What do you enjoy about your role? The challenge and the new skills that I am learning along the way. I also love that I can bring my science background and creative spirit together for a useful purpose.
Knowing what you know now, what advice would you give yourself in your first week in the industry? I think I would tell younger me to enjoy it and reap the benefits of working in an industry like this. It is so wide ranging and there are so many training courses, seminars, functions, onsite learnings, etc. to broaden your knowledge in so many varied areas. Can you share a challenging moment and how you worked through it? I can think of so many challenging moments, most of which include mud (and cars suck in it): can’t find bores, heat, snakes, cattle on the loose, malfunctioning equipment and rain events (where every site in Queensland needs you there yesterday). You have just got to take a breath and work through it step-by-step. Do you have any regrets? No, no time in life for regrets. You “can’t be what you can’t see”, so what advice would you give women who may never have thought about the extractive industry? It’s just like any other industry so why not work in it. Its varied and its productive and has a very important place in our communities. •

The researchers say the evidence discovered indicates the quarry was used in two primary periods. During the first period (approximately 12,840 years ago), the quarry was mined for red ochre and equipment to produce and repair weapons. After a hiatus of a century or more, the site was again used to mine red ochre, but also to deposit artifacts in the quarry pit.“Further excavation of the estimated 800-square-meter remainder of the site will certainly reveal complexity not captured by our sample,” the researchers said.Pelton nominated the Powars II site to the National Register of Historic Places in 2021.•

QUARRYING: AN 13,000-YEAR-OLD ART
The mine is said to have been used by humans to produce red ochre. Found at Sunrise in Platte County, the Powars II site is the oldest documented red ochre mine – and likely the oldest known mine of any sort – in all North and SouthFamedAmerica.archaeologist George Frison began theorising on the existence of the red ochre mine in 1986, and the excavations were completed shortly before his death in 2020. The findings appear in the paper: In situ evidence for Paleoindian hematite quarrying at the Powars II site (48PL330), Wyoming.Thepaper’s lead author is Wyoming State Archaeologist Spencer Pelton, who became involved in the Powars II project in 2016 when he was a UW doctoral student. “We have unequivocal evidence for use of this site by early Paleoindians as long as 12,840 years ago and continuing by early Americans for about 1,000 years,” Pelton said.“It’s gratifying that we were finally able to confirm the significance of the Powars II site after decades of work by so many, including Dr. Frison, who learned of the site in the early 1980s and was involved in the research until his death.” In a nod to his tireless work in the years before and during the project, Frison is listed as a co-author of the new paper.
Other contributors were George Zeimens, executive director of the Sunrise Historic and Prehistoric Preservation Society; Erin Kelley, a UW graduate and Office of the Wyoming State Archaeologist staff member; and UW Ph.D. students Sarah Allaun, Alexander Craib, Chase Mahan and Charles Koenig. Red ochre, also known as hematite, fulfilled a wide range of functions in Paleoindian societies, including as a pigment in rituals. Red ochre, also known as hematite, fulfilled a wide range of functions in Paleoindian societies.
The animal bones and antlers were used to extract the red ochre in the quarry during its use. The projectile points come from numerous locations in the region, including from as far away as the Edwards Plateau in Texas. That makes it likely that red ochre found at archaeological sites throughout the American midcontinent came from the Powars II “Beyondquarry.itsstatus as a quarry, the Powars II artifact assemblage is itself one of the densest and most diverse of any thus far discovered in the early Paleoindian record of the Americas,” Pelton said. “The site contains over 30 chipped stone tools per square meter, some of the oldest canid remains from an American archaeological site and rare or unique artifacts, among other distinctions.”
It has been found at ancient graves, caches, campsites and kill sites in the Great Plains, the Rocky Mountains and beyond.Among the artifacts previously discovered at the Powars II site are Clovis points- believed to be from the first inhabitants of North America – along with other projectile points, tools, and shell beads.The2017-2020 excavation led by Pelton yielded several thousand more Paleoindian artifacts, along with many well-preserved animal bones and antlers.
