size reduction in any crushing equipment. Basic Requirements of Crushing Equipments: An ideal crusher or grinder should have the following characteristics: a. It should have a large capacity. b. It should require a small (energy) input per unit weight of production. c. It should yield a product of uniform size or in the required size range.
The mined rock is transported to the processing site and stockpiled. The material then is crushed. Depending on the degree of cementation, several stages of crushing may be required to achieve the desired size reduction. Gyratory crushers, jaw crushers, roll crushers, and impact mills are used for primary and secondary crushing.

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamondrich depth is reached, the raw ...
