One hundred percent of the feed to a V-belt driven Double Roll Crusher must flow between the rolls, creating a ribbon of material and increasing the potential of creating additional fines due to inter-particle crushing taking place. The feed opening spans the length of the crusher rolls but only measures to the centerlines of the roll bodies.

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.
