used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. Obviously, a good liner design and the right operating conditions such as mill speed or balls filling degree, should limit the risk of projection. The purpose of this paper is to further explore the issue

For the raw materials that do not meet the feed size of the tumbling mill, they should be returned to the crusher and crushed again. Material particles that are too large will not only affect the output of the tumbling mill but also damage the liner in the cylinder and reduce the service life of the ball mill.

The feed (ore) size distribution used was also chosen to match the feed that would typically be used in such a ball mill test. It is relatively fine with a top size of 2.8 mm.This distribution has been truncated at 1.18 mm to keep the simulation size under 1 million particles in order to make the computational duration manageable.The effect of this cut off size will be …
