Pharmaceutical Technology: PRACTICAL I : BALL MILLING

A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.
