mermill with a slower hammer-tip speed while using a larger screen hole size. In fact, if all other factors affecting the two mills' efficiency are equal, each unit's ef-ficiency is directly proportional to its screen hole size. And if the two mills have the same size screen holes, the large-rotor, high-speed unit produces a finer grind.

Importance of the Hammer Mill Screen Make sure the proper screen is being used The size of the openings in the hammer mill screen greatly determines the size of particles which are produced. Using a 1/8 to 3/16-in. screen will have a mean particle size from 600 to 800 microns. Using a 1/4 to 3/8 in. normally produce particle size

Various types of size reduction equipment are available in the market. Based on the classification of size reduction equipment done by Scubert et al. (2004) and Woldt et al. (2004), Miu et al (2006) added an extended layout of this classification and suggested hammermill, knife mill, and disc mill as the proper equipment for biomass comminution.

size reduction. 3. Grinders like hammer mills, rolling-compression mills, tumbling mills, etc. Grinders are used for intermediate and fine size reduction. 4. Ultrafine grinders like hammer mills, agitated mills, fluid-energy mills, etc. The basic motive behind performing the size-reduction is to make too large to be used solid materials usable.
