3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

The design of all pre-industrial timber trusses was based on tradition, trial and error, and the carpenter’s intuition. There were no engineers or engineering principles to guide the design. Often, the carpenter’s intuition was flawed, leading to irrational or mongrel trusses, some of which have managed to survive.

In a non-reversible 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.
