Hammermills accomplish size reduction by impacting a slow moving target, such as a cereal grain, with a rapidly moving hammer. The target has little or no momentum (low kinetic energy), whereas the hammer tip is travelling at a minimum of 16,000 feet per minute (4,880 m/min) and perhaps in excess of 23,000 feet per minute (7,015 m/min) (high kinetic energy).

Simply put, roller mills are used for particle size reduction. They take raw material and reduce it into a usable size for a given application. More specifically, they are used to execute consistent, highquality particle reduction in nonfibrous materials such as grains, fertilizers, coffee beans, and other biomasses.

It is used when very high levels of retention of aromatic compounds are required. In this grinding method, size reduction is possible at subzero temperature ranging from 0 to − °C. The whole cryogenic grinding process can be divided into three stages: (1) coarse grinding, (2) precooling, and (3) fine grinding.
