Hammer Mills

A hammer mill is designed to crush, grind, pulverize, and shatter individual particles of solid material into smaller sizes.

Whether pepper, coffee beans, coal or asphalt, hammer mills can effectively reduce any raw material to a desired outcome through repeated impact.

Hammer mills have much higher throughput rates than roller mills, but hammer mills tend to have wide particle distribution rates.

Hammer Mill Diagram

Uniform particle size reduction occurs via repeated blows of moving hammers attached to a rotating shaft housed inside the mill’s chamber. Once material is fed into the chamber, the swinging hammers impact and accelerate the particles, where they collide against the chamber walls and against each other. Repeated impact and collisions will occur until the individual particles are small enough to pass through a screen located at the bottom of the chamber.

Generally, the faster the hammer tip speed, the finer the particles. Particle size is determined by screen size and hammer speed, thickness, quantity and distribution around the rotor. For example, to reduce stones to a fine size would require a high shaft speed with balanced symmetry, a smaller screen, and a high number of hammers.
