Optimization of mill performance by using

mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree. 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

ball mill liner | Magotteaux

Ball mill liner | Magotteaux

Uses of a ball mill liner The role of a ball mill liner is to give the mill heads protection against wear and tear thus increasing their lifetime and creating optimal grinding efficiency. The design of a ball mill liner depends on the drilling pattern of the mill heads, the rpm speed of the mill, the maximum grinding diameter of the media and the percentage of media filling.

Total primary milling cost reduction by improved liner

A ball mill is designed to run at 25% total filling degree with a fixed speed of 75% CS (critical speed). A lifter angle of 30 degrees will produce trajectories where the grinding media falls on the toe of the charge thereby limiting the risk of breakage. Due to the lack of available ore, the plant decides to
