An initial size reduction from material several centimetres in diameter down to one centimetre, or so, is often termed primary crushing. This may be followed by further size reduction, secondary crushing, and then pulverising, or fine grinding. The term micronising has become popular for the reduction of particle size to this dimension.

Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero electrical charges of the ...

Impact crushing reduces material by utilizing the theory of mass versus velocity in two ways. In one method, material can be broken by its collision with hammers that are fixed to a spinning rotor. The material is broken mainly by its initial impact with the hammer and then further reduced by its impact against the breaker plates.
