11 Crushing and classification

2021-5-14  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.
