PARTICLE SIZE REDUCTION TECHNIQUES SlideShare
Mar 25, 2016· BALL MILL Principle: The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig: Ball mill 13 14. Working: The drug is filled into cylinder 60% of the volume.

Pharmaceutical Grinding Mills with Classifier Milling Systems
Ball mills actually reduce the size of pharmaceutical agents through impact and attrition. Initially, the active ingredients are flattened by the colliding balls. The ball mill is an effective tool in grinding delicate, brittle and sticky materials. However, milling with ball mills is lengthy and time consuming. Cleaning also takes a significant amount of time – requiring at least a week. The ball mill is also a noisy machine .

Optimization of mill performance by using SciELO
Optimization of mill performance by using online ball and pulp measurements. In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs.
