Double-roll crushers compress feed between two inward-rotating rolls. Smooth rolls are used for fine crushing of softer to medium-hard material; corrugated or toothed designs serve different duties, including sticky feed. Roll-surface geometry, gap and adjustment design determine the application and product size. Confirm whether the machine is a compression roll crusher or a toothed sizer before specifying parts.
