    Nov 01, 2019 In general, the ball mill is ground by the impact energy applied to the materials owing to the dropping of the grinding media that is moved upward by the rotation of the mill. The normal force applied to the materials by the grinding media were calculated using the EDEM and can be seen from Fig. 10. When the total force is checked, the normal

    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
