Ball Mill Design Analysis

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 of the cylinder.

Pharmaceutical uses of Ball Mills


The small and average capacity Ball mills are used for the final grinding of drugs or for grinding suspensions.
