Rock Crushing Process in Mining

The coarse material that can't fall through will remain to be crushed with the next gyration. The speed of the crushing cycle depends upon how large the initial rock was, the revolutions per minute that the crusher is traveling at, and of course gravity. The speed in which the rock falls to the next nip- point.

Crusher - Wikipedia

Increases in rotating speed have provided the largest variation. For instance, a 48-inch (120 cm) cone crusher manufactured in 1960 may be able to produce 170 tons/h of crushed rock, whereas the same size crusher manufactured today may produce 300 tons/h. These production improvements come from speed increases and better crushing chamber designs.

Crushing Plant Flowsheet & Design-Layout

In the crushing section, the ore as it comes from the mine is broken down dry to a size suitable for the wet grinding machines ; these can, if necessary, be made to take lumps of 2-in. size, but they work much more efficiently if their feed is ½ in. or less. Before the advent of the cone crusher the usual practice was to make a 2-in. product in two steps consisting of a primary breaker ...

Quarrying Process And Quarry Products

Rock from the quarry face is fed into the top of the crusher and crushed rock falls out of the bottom of the jaws. The size of the crushed stone which passes through the jaws is partly governed by the gap set at the bottom of the jaws, though larger size rocks can pass through if the rock being crushed is slabby or elongate in shape.
