GRINDING MILL

How the Vibratory Mill works

The Mill consists of a grinding chamber and vibrating motor.
The grinding chamber is a vertical cylinder filled with small pieces of grinding media. Most often these are 13 mm alumina cylinders. The material to be ground is introduced into the voids between the grinding media. Thus, all the energy from the vibrating motor is imparted directly to the grinding media without the necessity for intermediate gears, drives or clutches.

The top eccentric weight causes a horizontal gyration of the grinding chamber, while the bottom eccentric weight provides a gyrating tilt. This unique motion causes three dimensional, high-frequency vibration.

Cylindrical media gives face, line and point contact for narrower particle size distribution. Ball media gives point contact for breaking up larger particles and for a wide size distribution
