Several Factors Influence The Efficiency Of Ball Mill

Several Factors Influence The Efficiency Of Ball Mill

Several factors influence the efficiency of ball mill grinding. the density of the wet feed should be as high as possible, consistent with the ease of flow through the mill. it is essential that the balls are covered with a layer of material. grinding efficiency also depends on the surface area of the balls. balls should be as small as possible and.The rod mills, which have a discharge port in one end of the shell, are called end peripheral discharge type (e.p.d. type as per fig.1), while those having a discharge port in the center of the shell are called center peripheral discharge type (c.p.d. type as per fig..
