The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines.
c The speed at which feed is introduced into the feedconditioning chamber affects the moisturetemperature relationship which in turn relates to pellet quality. d The amount of steam added to a given volume of feed should be in balance such that the drive motor on the pellet mill is operating at its maximum amperage.
The speed of milling is the distance in FPM Feet per minute in which the circumference of the cutter passes over the work. The spindle RPM necessary to give a desired peripheral. speed depends on the size of the milling cutter.. The best speed is being determined by the kind of material being cut and the size and type of the cutter used width and depth of cut finished required type of.
The distance between hammer and screen should be 0.5 inches 12 to 14 mm for size reduction of cereal grains. The velocity or tip speed of the hammers is critical for proper size reduction. Tip speed is calculated by multiplying the rotational speed of the drive source shaft rpm by the circumference of the hammer tip arc Formula 1.

Hammer mills consist of a series of hammers usually four or more hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact. The materials to be milled are struck by these rectangular pieces of hardened steel ganged hammer which rotates at high speed inside the chamber.
