A] Hammer Mill Working Principle and Main Components. The process of size reduction (for feed material) is carried out by rectangular pieces of hardened steel that rotate inside the chamber at a high speed, striking the material to be milled with a powerful force. These radially swinging hammers (from the turning central shaft) help crush/grind ...

size reduction. They found that the Retsch SK100 hammer mill was more energy efficient than the SM2000 knife mill due to the higher motor speed and axial feeding mechanism. Also, Su Dongping and Yu Manlu [21] analyzed the particle size distribution of the grinded material using a hammer mill and a knife mill. Their purpose was to evaluate it by

The high grinding capacity, less maintenance cost and ease of operations also makes the hammer mill a preferred grinding method. In addition, in feed manufacturing, the hammer mill is highly suitable for grinding fibrous materials such as hulls (oat, barley, wheat bran) compared to the roller mill and multicracker system.

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.

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 and attrition) of material against screen bars. Attrition crushing is most useful in the following two circumstances. When material is friable or not too abrasive.
