crushing and grinding Of ore. 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.
ore particle size. In the most grinding process of the concentrator, the construction investment and production and operation cost of grinding operation is much higher than those of crushing operation, so it is necessary to reduce the grinding particle size as much as possible.
