Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the Rolls. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the ...

A roll crusher is a type of crushing equipment used to reduce the size of materials. Size reduction is accomplished by compressing feed material between two cylindrical rollers that rotate in opposite directions. Before crushing, the material feeds into the gap between the rollers. As the rollers rotate, the material is compressed and reduced ...

This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged. Both of these statements are true, but the degree to which the product is affected depends to a much greater extent upon the ratio-of-volume-reduction in ...

Roll Crushers. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.

It will take larger than a 40-in. diameter roll crusher. A better solution would be to use a larger jaw crusher set at 1½ in., then a roll crusher from the Roll Crusher capacity Table above could be used. If the output of this crushing process should have less material of the +1-in. size, the larger crusher could be operated with a closed circuit.
