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.

Secondary and fine ore crushing, aggregate production, coal crushing, fertilizer production and refractory-material crushing.
Identify smooth, corrugated or toothed rolls and the actual drive and overload system. Record diameter, length, surface, gap, rotation and attachment. Double-roll crushers and sizers may both have teeth but differ in working zones and tooth systems; check roll shells, teeth, liners and drive parts separately.
No. Use the actual mechanism and OEM classification.
Provide the machine model, operating conditions and target service life so our engineers can recommend materials and prepare a quotation.
