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.
