Multotec leverages cutting-edge technology to scientifically design mill liners.

Multotec supplies scientifically designed mill liners to mining operations

Metallurgy and process engineering company, Multotec, has successfully supplied scientifically engineered rubber mill and scrubber liners to mining operations across the globe, including the USA, 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. The liners were developed using advanced computer simulations to ensure optimal configuration for efficient performance and have been implemented in mills, chutes, and plants. M ultotec 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 at Multotec, notes, “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.” Scientific design approach

this technology to support an installation. This approach enabled precise fitting and optimised liner performance. Multotec places a strong emphasis on ensuring that its liner design is optimal for the life of the liners and performance. The company also conducts condition monitoring on installed liners to ensure maximised uptime by facilitating proactive maintenance. Ralph Hollenstein, Senior Mechanical Engineer

Multotec 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
