PRINCIPLES OF CRUSHING, GRINDING id AND

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run - of - mine" ore, whi le grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
