SIZE REDUCTION AND SIZE SEPARATION

Hardinge mill: In this type of ball mills the cylinder has a conical end towards a discharge point. In this mill the larger balls remain within the cylinder and the smaller balls are collected in the conical portion. As a result, coarser grinding takes place in the cylinder portion and finer grinding takes place in the apex of the conical portion.

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. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
