CONT: Most crushers operate dry, that is, without the addition of water, the end product being discharged by gravity or the movement of the crushing elements.
CONT: Coarse, or primary, crushing today is most often done by squeezing until fracture occurs using large crushers capable of taking crude ore in sizes up to 7 feet (over 2 metres) in its largest dimensions and reducing it to lumps of from 1 to 6 inches (25 to 150 millimetres) in size.
