Hammer Mill Working Principle. The hammermill, fundamentally, is a simple mechanism. The "orthodox" machine comprises a boxlike frame, or housing, a centrally disposed, horizontalshaft rotating element (rotor) on which the hammers are mounted, and usually a set of circumferentially arranged grates in the lower part of the housing.

Buhrstone mills are one of the oldest types of mills used for grinding grains and hard materials. Disk attrition mills are modern versions of the ancient Buhrstone mill. Vertical shaft mills work on the same principal as VSI crusher, with a rotor on a vertically mounted shaft using centrifugal force to throw the media against a wear plate.

What to Look for in Hammermill Design. Hammermills include a rotor with rigid hammers connected directly to a shaft or swinging hammers connected to large plates fashioned with support pins around their circumference. A hammermill typically consists of four or more hammers used to grind the material into smaller particles through impact.
