Read More2013-12-24 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.
Read More2014-12-17 Ball milling is a method of grinding and mixing of materials, with or without liquid in a rotating cylinder or conical mill partially filled with grinding media. It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. ball milling machines enable very precise milling, in ...
