Hammer Milling Services. Hammer milling is a high energy process of reducing particle size by impact with rapidly moving hammers. The material is fed into the mill's chamber, where rapidly rotating hammers that strike particles repeatedly until the particles are reduced to a size that can pass through a screen.
