The grinding capacity test results of a model DTM350/700 ball mill was investigated. It has been found that the ball mill current at the condition of its maximum coal dust output isn't just the maximum current probably, and so current change has significance for judging the ball mill's blockage situation. This paper offers the theoretical analysis on the relationship between the coal storage capacity in the ball mill and coal dust output, and on the relationship between the coal storage capacity and the mill's power consumption. These analytic and calculated results not only are accordant with the actual trend of ball mill current change, but also can estimate the ball mill's optimal coal storage capacity under the conditions of different ball loading. The relevant findings can provide the theoretical guide for design and operation management personnel of ball mill.
