Description
Grinding of ingredients generally improves feed digestibility, acceptability, mixing properties and pelletability. Grain is typically pulverized in a grinder-mixer either by hammer mills or roller mills. Hammermills are impact grinders with swinging or stationary steel bars forcing ingredients against a circular screen or solid serrated section designated as a striking plate. Material is held in the grinding chamber until it is reduced to the size of the openings in the screen. The number of hammers on a rotating shaft, their size, arrangement, sharpness, the speed of rotation, wear patterns, and clearance at the tip relative to the screen or striking plate are important variables in grinding capacity and the appearance of ground feed.[1] A combination of cutting, attrition, and crushing occurs in rollermills. These are smooth or corrugated rolls rotating at the same speed set at a pre-determined distance apart with material passing between the two. A tearing action may be added by operating the rolls at d
