The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding is a high technological enterprise that integrated research
Overflow Ball Mill Appliion: The overflow ball mill has the advantages of relatively simple structure, no grid grille, high grinding fineness and relatively less ball loading, etc. It is widely used in the second stage of fine grinding or in the case of relatively fine products.
For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
