Ball mills steel ball mills lined ball mills particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s the basic construction of a ball mill is a cylindrical container with journals at its axis

Ball mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns to achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced

The amount and ball size distribution in this charge as well as the frequency with which new balls are added to the mill have significant effects on the mill capacity and the milling efficiency small balls are effective in grinding fine particles in the load whereas large balls are required to deal with large particles of coal or stone contaminant
