Media milling with high power density

100 kW required for industrial scale production can be applied to a commercially available 26 l mill with the same specific cooling surface and power density. In the case of the full space mill, the demand for an identical specific cooling surface leads to a virtually 20 times larger grinding …

Key considerations when selecting a mill lining system

A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action. To achieve this, the mill liner profile must be constructed from high wear resistant materials and incorporate ...
