What are Types of Grinding Mills? [Video]

grinding mills

Lab grinding mills pulverize, grind, and chop samples for routine lab analysis.

Select mills based on the type of sample you are working with, the sample capacity and the desired particle size.

Types of mills

Ring and puck

These use multiple grinding surfaces usually as opposing plates that move in opposite directions with a disc or puck moving and grinding materials on a plane.


Impact mills have a moving impactor that pulverizes a sample through repetitive motions

Ball or ball-medium

The ball mills grind through impact of a grinding media such as balls, rods, etc.

Vibratory or shaker

These mills use high speed vibrations and grinding media to combine multiple grinding forces to reduce materials to fine powders. These mills can include grinding forces and media like balls, beads and grinding media.


Combination mills use multiple techniques and forces such as combination of ball media with vibratory and shaking motions
