The ball mill has higher circulation load, it generates only 30 -35% of actual fines you require to be called as product. If your product size needed is passing 45 micron, then the ball mill total discharge material will contain normally 30% of 45 micron. The rest is oversize which has to be ground again. #### Ball Mill Design/Power Calculation - Mineral Processing

Mill type. These conditions have been built into factors which are given in the figure above. The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge.
