Crushers can be categorised based on the crushing stage or the reduction technique used. For the stage of crushing, crushers are classified as primary crushers, secondary crushers, and tertiary crushers [6]. Compression, impact, shear, and attrition are the four main reduction techniques used to reduce the size of solid materials [7], [8 ...
