Mineral processing - Wikipedia
Crushingand grindingare the two primary comminution processes. Crushing is normally carried out on "run-of-mine"[3]ore, while 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.
