Unit OperatiOn Size Reduction

Grinding is achieved by mechanical stress followed by rupture and the energy required depends upon: 1. the hardness of the material 2. the tendency of the material to crack (friability). The force applied may be compression, impact, or shear, and both the magnitude of the force and the time of application affect the extent of grinding achieved.

Grinding and pulverizing the ore is performed later in the ...

Dust control for the crushing and grinding processes is normally achieved by either wet suppression or LEV systems, or a combination of both. Spraying the ore with water sprays to coat the outer surface helps to prevent dust from becoming liberated. Applying the water to the ore before it enters the crushing or grinding unit is most effective. In addition, it has been shown that the water ...
