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.

the hammer pattern. For most large diameter hammermills using hammers that are over 10" long, a ratio of HP per hammer is fin e when using screens larger than 8/64". For smaller screens it may be necessary to increase the number of hammers used in the hammer pattern to prevent rocking of the hammers on the hammer pins.

Among those styles, the functionality of a hammer mill remains basically the same: Material is fed into a grinding chamber. Contact with moving hammers, and interior mill components reduce the material's size. Material remains in the hammer mill's grinding chamber until it is able to pass through a screen or grate with certain size openings.

What is Hammer Milling? Hammer milling is a high energy process of reducing particle size (comminution) by impact with rapidly moving hammers. The material is fed into the mill's chamber through a feed chute, typically by gravity, where it is struck by rapidly rotating hammers that strike particles repeatedly until the particles are reduced to a size that can pass through a nearby screen.
