Question 1

What is a hammer mill?

Schutte Hammermill · Accepted Answer

A hammer mill is a size reduction machine that uses high-speed rotating hammers to impact and break material into smaller particles. Material remains in the grinding chamber until it is reduced sufficiently to pass through the mill's screen or grate.

Hammer mills are used for applications ranging from coarse crushing to fine grinding, depending on the equipment configuration, material characteristics, and desired finished particle size.

Question 2

How does a hammer mill work?

Schutte Hammermill · Accepted Answer

Material enters the hammer mill's grinding chamber and is repeatedly impacted by hammers attached to a high-speed rotor. Impact between the hammers and material, along with particle-to-particle and material-to-machine impact, reduces the material in size. The reduced material exits through a screen or grate once it is small enough to pass through the openings. Rotor speed, hammer configuration, screen size, and material characteristics all influence the resulting particle size.
