The capacity of the singleroll crushers is a function of the roll gap the roll length and the speed and ranges from about 30 tonsh 27 metric tonsh for a 24inchlong 61 cm roll crushing to ¾ inch 2 cm up to approximately 1500 tonsh 1360 metric tonsh for an 84inchlong 213 cm roll crushing to pass 10 inches 25 cm

Two types of roll crushers are generally designed In the first type both rolls are rigidly fixed to a frame with provision for adjusting the lateral position of one of the rolls to control the gap between them Once set these rolls are locked into place One roll is attached to the driving mechanism while the other rotates by friction

The crushing rolls for primary and secondary crushers are made up of a roll body in polygon design which is equipped with exchangeable crushing segments As a result of the specific geometry between roll body and crushing segment an optimum tight fit is achieved thus being able to stand up to the high crushing forces

Materials to be crushed become more and more difficult in terms of handling high throughput capacities are required and the energy input is a key focus Therefore the application of energyefficient roll crusher with high throughput rates becomes more and more important from the economic and ecologic point of

A Single Roll Crusher is made up of a toothed roll assembly which crushes the incoming feed material against a crushing plate The Single Roll Crusher is designed to reduce larger feed sizes to the desired product size at a 61 ratio of reduction while producing a considerably lower percentage of fines

Roll crushers handle very abrasive material with minimal wear and can crush at ratios up to 8 to 1 depending on product characteristics roll speed differential speed if any and roll gap The roll gap is adjustable from 1 mm very low throughput and maximum fines to 30 mm gap for very high throughput with minimum fines
