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.
