201611 Gyratory Crusher Circuit Design. In practice, large primary gyratory crushers are seldom installed underground. They are invariably installed at the surface. The charge is preferably fed directly off trucks, tip-wagons, side dump rail cars and conveyor belts onto a receiving hopper, which feed the crusher through a chute. Usually, a grizzly isاحصل على السعر
2023223 The cone crusher operates by means of a rotating mantle, which gyrates against a stationary bowl liner. The materials that are fed into the crusher are crushed between the mantle and the bowl liner. One advantage of a cone crusher is that it is capable of producing a finer product than a gyratory crusher.احصل على السعر
