Ball Mill Principle, Construction, Working, and More Soln Pharma

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

What Are the Differences between Dry and Wet Type Ball Mill?

What Are the Differences between Dry and Wet Type Ball Mill?

The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform. The wet ball milling can not only grind agglomerate into fine particles, but ...
