SIZE REDUCTION BY CRUSHING METHODS

Size Reduction is mainly done through crushers and mills. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on the "runofmine" ore. The grinding process which is normally carried out after crushing, may be conducted on dry or slurried material. The size reduction process:
