A hammermill is one of several types of crushing machines, including impact crushers, jaw crushers, and cone crushers, that is manufactured for the purpose of processing raw materials to reduce them in size. In the crushing industry, there are two types of forces used to reduce the size of materials: impact forces and compression forces.

ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materials become very abrasive; therefore, they are not suitable for highspeed hammer mills. In a typical jet mill, grinding action is caused mainly by particleparticle collisions, so wear to the mill's internals is less of an issue.

A hammer mill is a rock crusher that employs a rain of hammer blows to shatter and disintegrate a variety of materials. Hammer mills produce a finished product size that is dependent upon the following criteria: Openings in perforated screens or grate bars. Number, size, and type of hammers. Grinding plate setting.
5 Construction, Working and Maintenance of Crushers for Crushing Bulk Materials In a nonreversible hammer mill with screen bars, shown in above figure, material is broken first by impact between hammers and breaker plates and then by a scrubbing action (shear
LC201 model is recommended for crushing 2in (51mm) and smaller samples. It processes at a maximum rate of about 1,000lb (454kg) of coal material per hour.

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.
