Dual Stage

Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill’s chamber through the feed chute, typically by gravity, where it is struck by ganged hammers attached to a shaft that rotates at high speed inside the mill’s grinding chamber. The material is crushed or shattered by a combination of repeated hammer impacts, collisions with the walls of the grinding chamber, and particle on particle impacts. Perforated metal screens or bar grates covering the discharge opening of the mill retain coarse material for further grinding, while allowing properly sized materials to pass.

We offer an extensive line of hammer mills suitable for a wide variety of applications, and include wood grinders, industrial, full circle screen, and laboratory scale styles. Most models are available in gravity or pneumatic discharge.
