The ball mill is the important equipment in the mining industry, with the development of the macro-scale ball mill, and is more difficult of liner's wearing,installation and taking apart. The service life which raises a liner will prolong the production period that the ball mill, influencing an economic benefit of the concentrating mill.
In a dynamic situation, the breakage rate or selection function is dependent on the type of tumbling mills. For ball mills the selection or breakage function is generally not affected by mill holdup and can be treated as independent of time.

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...

Sep 23, 2014 · Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).
