Design, Fabrication, and Performance Evaluation of a Hammer Mill
Hammer mill is one of the machines used in size reduction. Hammer mills reduce particle size by breaking due to the impact of the hammers, shearing by the edge of the hammers and screen, and collision among the product and in between the product and machine. The impact is the primary force to reduce particle size in a hammer mill.

A preliminary simulation model for fine grinding in high speed hammer mills
2004年6月25日 High speed hammer mills break particles suspended in gas by high velocity impact against a hammer surface. Assuming that the action is comparable to a stream stagnating against a surface, it is shown that the net mill power can be calculated and it is predicted that the power varies approximately proportional to the hammer speed cubed.
