Working Principle

The Mixer Mill operates on the principle of impact and friction.

Process:

Sample is placed in grinding jar with balls
Jars oscillate at high frequency
Grinding balls impact and crush sample
Continuous motion ensures uniform grinding

This results in fine and homogeneous sample preparation.
