significance of load detection of kaolin ball mill

power draw calculator of ball mill. Calculation of the power draw of dry multi compartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous So direct measurement must be taken for calculation of mill load

Optimization of mill performance by using

2015-4-16  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
