The ball mill is the important equipment in the mining industry, with the development of the macro-scale ball mill, and is 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.

The service life which raises a liner will prolong the production period that the ball mill, influencing an economic benefit of the concentrating mill. Therefore, it is of great significance for dynamics simulating on the grinding ball, studying of grinding ball on dynamics characteristic and improving the liner shape,reducing relative slide, and extending the liner’s age.

Apr 01, 1999 The first systematic formulation of power draft by analyzing ball trajectories goes back to 1919 and since then a considerable amount of effort has been put to correlate power draft and operating and design parameters of the ball mill. However, most of the theoretical formulae available to quantify power draft until now, do not take into.
