Grinding is accomplished by many types of manual and mechanical operations involving impact, attrition and cutting. a) Hammer mills: are mostly impact grinders with swinging or stationary steel bars forcing ingredients against a circular screen or solid serrated section designated as a striking plate. The material is held in the grinding chamber until it's reduced to the size of the openings ...

The main advantages of the attrition mills are the relatively high energy utilization, fast and efficient fine grinding, proficient temperature control and simple operation [1]. The feed material is comminuted among the moving media, the stirrer, and the grinding chamber wall by friction, impact, and compression forces.

Attrition mill is a principle in which grinding balls are moved by rotating the impeller, and biomass is crushed by the impact and shear actions exerted by the grinding balls. Crushing and dispersion times are significantly faster than those of general ball mills. In particular, attritiontype mills can be rather easily scalable
