tumbling mills. These contain a charge of loose crushing bodies-the grinding medium-which is free to move inside the mill, thus comminuting the ore particles. The grinding medium may be steel rods, or balls, hard rock, or, in some cases, the ore itself. In the grinding process, particles between 5 and 250 nun are reduced in size to

carried out by size reduction performed by crushers and grinding mills. The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution.

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on run-of-mine 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. More
