Date: . The process of turning large-particle materials into small-particle materials by external force is called crushing, and the machinery used is called a crusher. The process of turning small particle materials into powder materials by external force is called grinding or milling, and the machinery used is called grinding machinery.
A whole range of grinding/milling techniques and equipment are available for application with different types of food. Grinding/milling can be carried out dry or wet. In wet grinding/milling smaller particle sizes can be attained. Often dry grinding (milling) is combined with sieving or air classification, this results in particle size ...
