Roll Crusher

Figure 6.4 is a typical set-up where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a roll crusher. Such circuits are chosen as the feed size to standard roll crushers normally does not exceed 50 mm.

Roll Crusher – Kumera – Creating Efficiency | Kumera ...

Benefits of the Kumera Roll Crusher. reliable Kumera drive system. effective operation. high capacity: 35 t/h. robust construction. low maintenance requirements. low CAPEX and COPEX figures. Crushers are of heavy duty design and therefore suitable for crushing hot and abrasive materials. This is achieved by using water-cooled rotors, external ...

Roll Crushers

2016-1-1 · A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8. Estimate: 1.
