What is a roll crusher? Mineral processing equipment

14/2/2020· A Roll crusher is a size reduction machine consists of two rolls space from each other by a gap opening. The rolls rotate towards each other. The ore enters the feed opening, being rolled and ground between the surfaces of the rolls faces, then discharged out of the crusher under gravity and rotating actions. The motion of rolls results from a circling action of two shafts on which the rolls

This type of primary crusher is usually used for crushing shale to reduce it to a size suitable for handling. Roll Crusher. For a given reduction ratio, single-roll crushers are capable of reducing ROM material to a product with a top size in the range of 200–18 mm in a single pass, depending upon the top size of the feed coal. Double-roll crushers consist of two rolls that rotate in

Crusher Feed Size and Roll Diameter. The diagram in Figure #3 shows the method used in calculating maximum feed size for any diameter of rolls; the accompanying table gives a listing of feed sizes for standard diameters. These figures are based upon zero roll spacing; therefore the distance between faces (i.e., the discharge spacing to be used) should be added to them to obtain the maximum

Dual roll crushers, how they function

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 gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.

A combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a Williams roll crusher. The material enters the roll crusher machine and is impacted by the roll as it rotates. Then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material. The rolls act as flywheels, contributing to
