Both types are tipped at the wearing edge with various abrasion resistant alloys. Rotor speed affects the fineness of the grind as follows: low speeds result in a coarse grind and high speeds produce a fine grind. Size and shape of the retaining screen openings also affect the product. In general, a finer screen opening will result in a finer ...

FEECO hammer mills utilize a central rotating shaft, fitted with several "hammers" affixed to pivots on the shaft. As the shaft spins, the hammers are swung via rotational energy, causing them to collide with the material, breaking it up into smaller particles. Hammer mills are flexible, and can be used in a variety of applications.

Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.
