The weight of the mill lining also came down with the switch from pure metal to a metal-rubber compound, Norilsk said. “The new mill liner weighs close to 130 t, which is 120 t less than the old mill liner. The average weight of one mill liner element is 1.8 t (elements have different configurations and respective mass),” the spokesperson said.
Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.

Feb 01, 1993· In the mineral processing industry, ball mills are used to reduce ore from one size distribution to another. Ball mill wear occurs as a result of the violent interactions within the ball charge. In the present article, a mathematical description of wear has been added to a ball charge motion model.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
