Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, drawing and measured dimensions before ordering or manufacture.

Material Information

  • ZGMn18Cr2 is a candidate material for roll shells and crushing walls. Confirm the grade, heat treatment and in-service hardness against part drawings and operating conditions.
  • Cr26 high-chromium cast iron: a candidate roll-surface material for low-impact, highly abrasive duties.
  • Hardfaced composite: a chromium carbide wear overlay on the roll surface, with repair subject to the approved procedure.
  • Hardox 500: side and housing liners.

Brand Applicability

FLS ERC 18-14 / 22-20 / 25-25 / 25-30 / 25-34 range; identify legacy thyssenkrupp Mining installations by nameplate.

Industry Applications

Primary crushing of gold, copper and iron ores; underground and mobile crushing stations; aggregate production; and cement raw-material crushing.

Materials for similarly named parts may differ by OEM, machine model and operating conditions. Confirm the machine model, drawing and measured dimensions before ordering or manufacture.
Identification

Identification and Inquiry Checks

Record ERC prescreen, jaw liner, roll liner, adjustment and drive/support interfaces separately. Provide model, serial number, wear profiles, fastening, screen openings and material. Generic double-roll teeth cannot substitute for an ERC roll liner; capacity and energy comparisons need a matched-duty baseline.

Identification FAQ

Is an ERC roll liner a generic sizer tooth?

No. Verify the machine design and fastening system.
