Drug Milling: Particle size reduction is a common unit operation in pharmaceutical formulation. Reasons range from improving homogeneity and dose uniformity to increasing bioavailability to making drug products suitable for parenteral delivery.
At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill. By this means the maximum size reduction is obtained by impact of the particles between the balls and by attrition between the balls. Generally it is 0.5 cycles per seconds (cps).
