The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.

2019-12-24The motion of the charge, that is the grinding media and the material undergoing grinding, within a mill is of considerable theoretical interest and practical importance, and for these reasons, has been the subject of considerable study by a number of workers, but, even so, no rigid and complete theory, covering all the aspects of the dynamics of the mill charge, has yet been produced.
Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by Residence time of the material in the mill chamber. The size, density and number of the balls. The nature of the balls hardness of the grinding material Feed rate and feed level in the vessel. Rotation speed

In Fig. 3, as anticipated, at a given ball size, a higher rotation speed rpm yields a finer average particle size due to the higher number of rotations within a given period of milling time 12 h.Interestingly, at each rotation speed, there exists an optimal ball size at which the most reduced average particle size is achieved among other investigated ball sizes.
