power of the semi-automatic mill was studied, and it was found that the operation of the mill at low speed and low filling rate requires less cost and more economical. Therefore, when the rotation speed of the semi-automatic mill is 12.5r / min and the filling rate is 30%, the grinding efficiency of the semi-automatic mill is the highest [4]. 4.
