The proper operating speeds of ball mills vary inversely as the square root of the diameters. The proper operating speed of a ball mill increases as the size of the ball load increases. Due to interference between the balls, the volume of the charge should not be over 60 per cent, of the volume of the mill.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.

Planetary Ball Mills are used wherever the highest degree of fineness is required.In addition to well proven mixing and size reduction processes, these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and
