HEAVY ENGINEERING AND WEAR PARTS
The opening of the CMS Cepcor Australia Perth facility follows a period of team- and businessbuilding in the market and region
needed to have a robust and extensive offering to match our competition.”
The subsidiary is led by Jamie Poole, Managing Director, who has two decades of management experience in the aftermarket crusher space in Western Australia. One of his first moves was to appoint Screenmasters Australia for distribution on the east coast of the country.
The late-2024 opening of the Perth facility for the subsidiary follows a period of team- and business-building in the market and region.“ The business has secured new premises with craneage capacity capable of handling major crusher components up to 50 metric tonnes,” CMS Cepcor said.“ This facility will enable the business to hold extensive stock of crusher spare parts and major components.”
The Perth team is comprised of“ an experienced engineering and sales support staff, with plans to expand now we have the new premises”, Weare said.“ That will entail our team being able to offer liner optimisation and specialist wear solutions, as well as a comprehensive range internal mechanical spare parts and major assemblies for popular crushers used in the local market.”
CMS Cepcor expects the global expansion to continue through, mainly, development of the existing markets based on the potential within them, according to Weare.“ Chile and Australia are the key targets, but we are seeing growth in a number of our export markets,” he added. Weare concluded:“ The group has doubled its turnover in the last five years primarily driven by our successes in the North American market, with CMS Cepcor Americas and Columbia Steel Cast Products.
That has been the driver for growth, placing the group now with a turnover well in excess of $ 100 million and global inventory now approaching $ 40 million.”
The power of 3D scanning
Multotec says it has successfully supplied scientifically engineered rubber mill and scrubber liners to mining operations across the globe, including the US, Zambia, Ivory Coast, Botswana, Namibia and South Africa for various customers in the diamond, PGM, iron ore, zinc, lead, copper, gold and coal processing industries.
These liners were developed using advanced computer simulations to ensure optimal configuration for efficient performance. They have been implemented in mills, chutes and plants.
Multotec demonstrated the power of 3D scanning technology during a mill liner installation at a gold processing facility in Alaska, marking the first time it used this technology to support an installation, the company says. This approach enabled precise fitting and optimised liner performance.
Ralph Hollenstein, Senior Mechanical Engineer at Multotec, noted:“ In this case, the client supplied us with 3D scans of the mills, allowing us to design the liners remotely, creating shorter turnaround times and greater accuracy. The liners were then designed, manufactured and fitted perfectly in the mill.”
Multotec says it adopts a scientific approach in its mill liner design, focusing on process flow and charge trajectories to enhance both performance and durability of the liners. By using advanced modelling techniques, Multotec provides mill operators
with precise guidelines to keep the mill operating in its optimal regime.
As part of the design process, Multotec uses the discrete element method( DEM) to predict the behaviour of the mill charge − comprising ore and grinding media − and the performance of the mill throughout the lifespan of the lifter. DEM is also employed to predict liner wear and the evolution of the liner profile over time.
“ This technology enables us to simulate wear on the liners and track how the material interacts with the changing liner profile as it wears down,” Hollenstein explains.“ From these wear simulations, we can identify areas of high wear within the mill and use this information to optimise the liner design – adding material in high-wear zones while reducing material in areas that don’ t require as much reinforcement.”
Multotec’ s liner optimisation system integrates advanced tools, including MillTraj( a first order simulation tool), DEM( for advanced multiparticle simulation) and 3D scanning technology for mill liners. These tools enable precise condition monitoring, comprehensive management and effective liner design for enhanced performance.
MillTraj focuses on the trajectory modelling of grinding mill liners and lifters. Its key applications include:
• Simulating lifter designs and configurations to understand their impact on the motion of the grinding charge( balls and material) inside the mill;
• Optimising mill liner profiles to improve grinding efficiency and reduce wear; and
• Providing insights into the trajectory of grinding media to ensure optimal energy transfer and to avoid damaging the mill shell.
