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.
