Optimization of mill performance by using SciELO

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

Effect of ball size and powder loading on the milling

In this figure the negative influence of the smaller ball size on the milling efficiency is drawn by an arbitrary positive slope with ball size rather than the dependency of d 4 because in an actual dynamic ball mill situation the balls already existing in the turbulent medium is moving rather than in stationary state and thus the effect of
