Demand soars for Brakpan company a er replacing sand screw classifier with CDE EvoWash As a bonus, we have been able to commit to safer operations as CDE equipment is both high tech systems and simple to use, with well-conceived safety details that guarantee a comfortable working environment
Following the installation of a CDE EvoWash 72 on their sister company's site Analiza, South African brick and block manufacturer Multi Crete Bricks “just can't keep up with orders”, according to its CEO Christo Niemand. Multi Crete has been supplying the South African construction industry for 16 years, delivering premier quality brick and block products nationwide as well as supplying customers directly at their Brakpan factory. e company not only ensures that the best raw materials are selected but also guarantees the best end product by overseeing production from start to finish. In 2016, Multi Crete saw an opportunity to take the lead in the local materials washing market. To achieve this, an upgrade of its sand screw washing plant was necessary in order to remedy the substantial loss of valuable fines that ended up in its quarry's dam. By installing a new CDE EvoWash sand washing plant on its Analiza quarry, Multi Crete can now continue to produce its own bricks, blocks, and manufactured washed sands with an additional plaster sand.
A direct approach for a better solution Christo Niemand is a savvy and practical businessman who relies on a combination of word of mouth and direct communications with experts who can demonstrate the value of their equipment in a 'seeing is believing' manner. In this spirit, the Multi Crete CEO, who manages 16 employees, as well as quarry sta , visited a close-by quarry with a CDE representative to witness the e ciency of the CDE materials washing equipment in action. Convinced by the high tech but userfriendly aspect of CDE installations, Mr Niemand took the next step and challenged Nicolan Govender, CDE Regional Manager for Africa, to find the best-value-for-money washing solution that would significantly reduce the amount of lost fines, increase production levels and sand quality, and crucially allow for multiple sands to be manufactured. e objective was to boost Multi Crete's o er and subsequently demand. e CDE EvoWash 72 dual sand washing plant ticked all of these boxes and Niemand says that he is now ready to further upgrade his equipment to meet the newly created and ever increasing demand for Multi Crete's products. Niemand explains: “ e combination of a solid relationship with our local CDE experts and the commissioning of an ultraperformant EvoWash has given Multi Crete's activities a positive boost. Our plaster sand is hands-down the best in the region and being able to produce two products at the same time, including plaster sand, is truly remarkable.” e Analiza quarry treats raw materials including crushed rocks, a mixture of granite and silica, some being heavily claybound. It now produces 23 tonnes per hour of plaster sand and 19 tonnes per hour of river sand. e EvoWash allows for two products to be produced at the same time and can also be set to alter the amount of finer sand in the end product, allowing the

SKF rotates to its core strength – bearings SKF has taken a strategic decision to shi its global business focus back to the company's core strength – bearings.
As a leading global technology provider since 1907, SKF has over the years developed a holistic product and service o ering that is integral to bearing performance and reliability. “Since 2007, we have been placing our energy into seals, lubrication, power transmission, mechatronics, condition monitoring and engineering service solutions to support our quality bearing range, and this we have done with great success,” says SKF Services and Solutions Manager for Southern Africa, Sarel Froneman. “But we may have been too successful, losing focus on what is fundamental to our rotating technology solutions namely our bearings.”
engineering usually deals with more complex requirements such as upgrades and customisations and may involve an investigation of the bearing for example. In consultation with the customer, the application engineering team can develop a complete and optimal rotating technology solution with bearings at the core. e SKF application engineering team's capabilities extend to modifications of standard products such as the manufacture of special sealing arrangement, changes to bore-sizes on standard couplings, etc. Froneman adds that his team can also modify entrances for condition monitoring or lubrication services.
According to Froneman, there are customers who have standardised on SKF's products and systems that do not necessarily use SKF bearings. He cites one such example of a local coal mine that has standardised on SKF's condition monitoring systems yet their crushers, conveyors, electric motors, gearboxes, etc. may not necessarily be equipped with SKF bearings. “So while the mine is a key SKF customer, they may never have placed an order with SKF for our core product!”
Bearing remanufacture is another key function of SKF's application engineering. “Our basic remanufacturing service can restore unused bearings that have passed their shelf life to 'as new' at approximately 15% of the cost of a replacement bearing. For bearings that have been in operation, we o er a full Level 4 remanufacturing service. Alongside substantial savings on cost compared to a new replacement unit, remanufacturing also o ers the advantages of fast turnaround times and a reduced carbon footprint as less new steel is required.”
While SKF continues to hold its solid reputation as a leading supplier of quality bearings, SKF CEO, Alrik Danielson believes that SKF must once again become the world's number one bearing company. “Our mandate is therefore to raise the profile of SKF bearings across all our product and services o erings,” states Froneman. “Our bearing o ering should remain our number one priority and common denominator of all our rotating technology products and services.” “ is having been said, we must not lose sight of the fundamental role of our application engineering and asset management service solutions.” SKF's application engineering is an integrated range of products designed to support the integrity of rotating machinery, the most critical components being bearings. SKF rotates to its core strength bearings. 22
Froneman explains that application
SKF's asset management services embrace maintenance solutions based on asset criticality geared to minimise the risk of failure by optimising equipment reliability and subsequent equipment life for maximised uptime. is move underlines the new SKF Group vision – 'a world of reliable rotation' and demonstrates the company's understanding of what customers ultimately want - improved productivity and lowest possible ownership costs through reliable equipment performance and extended equipment life. In conclusion Froneman states that it is not about selling as many bearings as possible. “Bottom line, by adding value through o ering holistic rotating technology and service solutions, we build long-term customer partnerships.”

Four ways to optimise pump performance Pumps are the foot soldiers of the process industry, but their quiet dedication means they are o en ignored.
Ignoring the pumps is a big risk, because when these components break down – or run below optimum e ciency – the whole process su ers. Manufacturing and process companies are under huge cost pressures at the moment, making it vital to maximise assets and maintain uptime. ere are ways to optimise their performance in four di erent ways. e right bearing Bearings in centrifugal pumps support hydraulic loads imposed on the impeller, the mass of the impeller and sha , as well as loads due to couplings and drive systems. ey also keep the sha axial and radial deflections within acceptable limits for the impeller and sha seal. e bearings o en will face high axial loads, marginal lubrication, and high operating temperatures and vibration, all while the bearings attempt to minimise friction — which, if uncontrolled, can result in power loss, excessive heat generation, increased noise or wear, and early bearing failure. So, first and foremost, evaluate bearings (types, designs and arrangements) in the context of their anticipated operating environment. Suitable bearings are available to satisfy even the most di cult conditions faced by centrifugal pumps.
e right bearing, proper lubrication, a good sealing system and monitoring pump health performance will help to optimise pump performance 34
liquids, exclude contaminants, separate fluids and confine pressure. e choice of seal for centrifugal pump bearings depends on the unique demands and operating conditions of the application. Keep in mind, though, that the bearing and sealing arrangement represent an integrated system. Dynamic radial seals generally are the best choice for centrifugal pumps. ese seals create the barrier between surfaces in relative motion. Seal selection ultimately must be based on a thorough review of application parameters and environmental factors. Particularly in pump applications, for example, seals will be exposed to relatively constant pressure di erentials — making pressure seals (in which the seal cavity is pressurised) the preferred choice. Seals usually provide a much shorter life than the components they protect so don't fall into the common habit of scheduling seal replacement only at intervals dictated by requirements of other components such as bearings.
Monitoring pump health Regular measurement and analysis of key physical parameters such as vibration and temperature can detect pump system problems before they occur. Basic instruments can assess and report on vibration, temperature and other parameters. More advanced tools include online Proper lubrication Improper lubrication accounts for more than surveillance systems and so ware that can deliver real-time data.

Using Degraded Land to Drive Renewable Energy Development and Job Creation Promethium Carbon is a dedicated carbon and climate change advisory firm. e company enjoys the position of being a trusted advisor to major international corporations operating out of South Africa. ey are knowledge leaders in the carbon industry, and advise government and private sector on climate change and energy-related matters. Services include carbon project development, foot printing and disclosure and climate change strategy development. More information is available at www.promethium.co.za
Degraded land can be used to create renewable energy solutions for communities, according to a feasibility study by Promethium Carbon for a community based renewable energy project. e feasibility study, funded by the Prosperity Fund under the British High Commission, was presented in Johannesburg on 17 March. Promethium Carbon presented its answer to the challenge to use degraded land to create renewable energy solutions for communities, with the Merafong Case Study for Renewable Energy and Community Upli ment as well as with the release of an updated and extended Renewable Energy Toolkit. e project aimed to diversify the economic activities in the area and reduce dependency on mining, therefore building community resilience. e added benefit is energy produced with low carbon emissions, contributing to South Africa's national greenhouse gas mitigation e orts, as well as restoring the grasslands to their original pre-mining state. Sites for the biomass production and bioenergy plant were identified for the Merafong Bioenergy Project through interaction with mining companies operating in the Carletonville area of the Merafong local municipality. Harambe Sustainable Ventures (Pty) Ltd, a BBBEE mine rehabilitation and bioenergy/wasteto-energy power generation company, will be developing this bio-energy project. Byproducts include the production of biochar, for remediating soil by increasing the carbon content and potentially supplying waste heat, for use by new industries attracted to the area surrounding the biomass power plant. A locally developed pyrolysis plant will provide heat energy to an Organic Rankine Cycle generator set, producing 2 MW output which will be wheeled to the o taker.
36
Funding for the project will depend on a mix of equity, debt and concessionary funding. Debt funding will be secured from local institutions such as the Industrial Development Corporation, the Development Bank of SA and commercial banks. e loan will be paid back with revenue from the sales of electricity and biochar. “ is project will open the power generation market in South Africa to small businesses, enabling them to develop smallscale renewable energy projects for commercial use. It will lead to the creation of 'green' jobs, increased power generation from renewable sources and land restoration,” says Robbie Louw, director of Promethium Carbon. e British High Commission expressed its delight for the opportunity to be a partner in this project. “It demonstrates how a bioenergy project can positively impact the lives of local communities and help to build local commercial opportunities,” Tom Moody, Head of Regional Prosperity at the British High Commission, says. e Merafong Local Municipality, in conjunction with the West Rand District Municipality, is developing a bio-energy industrial park where projects such as this have the required regulatory support for development. Nikisi Lesufi of the Chamber of Mines said the project demonstrated cost-e ective benefits to mine rehabilitation, with positive community impacts a er life of mine. “ e use of abandoned and/or degraded land has long been an issue of concern and this project showcases the possibilities of converting, rehabilitating and producing positive advantages to communities through, what in essence is commercial farming, with the production of electricity.”
