Grinding MediaLining Media Liner Wear Rate Modelling

Grinding MediaLining Media Liner Wear Rate ModellingPrediction. It is at once seen that there is close agreement between the rate of production of specific surface in a mill and the rate of ball wear, insofar as these quantities depend on the speed of rotation of the mill. It is also found that for slow speeds, (N/Nc)< 0.6, the

Optimization of mill performance by using

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. (plan a liner change and/or change mill speed if possible).

A generic wear prediction procedure based on the discrete

Therefore, the average wear rate is lower for 2D meshes than for 1D meshes (with the same initial profile), provided that the liner evolution was predicted with the same wear constant. This reasoning is a strong argument for designing ball mill liner plates with initial grooves similar to those of the worn liner.
