grinding ball loading to the mill
Ball Mill, Improve The Crushing Rate Of Ball Mill. When the load is fixed, if the diameters of steel balls are too big, numbers of steel balls are very small, and then the collision probability between steel balls and ore particles will reduce. Also the grinding efficiency of ball mill will reduce.Get Price
