Roll Crushers
When a large quantity of rock is held between the rolls and subjected to high pressure, then comminution could take place by compressive forces as well as by interparticle breakage, provided again that the total applied pressure was greater than the crushing strength of the rock pieces. The product again is a continuous 'ribbon' of …
