All parts are OEM-compatible and available in multiple material grades (Mn13Cr2, Mn18Cr2, Cr26 high-chrome iron, Cr-Mo alloy steel, WC-Co cemented carbide) to match your specific ore conditions.

What materials does Anranst recommend for MMD MMD Sizer Teeth & Segments wear parts?

Material selection depends on your crushing application: Mn13Cr2 (ASTM A128 B-2) for moderate impact with work-hardening; Mn18Cr2 for harder abrasive feed with 30-50% longer life; Cr26 high-chrome iron for high-abrasion low-impact zones; Cr-Mo alloy steel for SAG mill liners; WC-Co for HPGR studs. Our engineers can recommend the optimal grade based on your ore characteristics.

How long is the delivery time for MMD MMD Sizer Teeth & Segments wear parts?

Standard sizes are available for rapid delivery. Custom orders typically ship within 4-6 weeks. Emergency supply is available for critical operations with 72-hour delivery for in-stock items. Contact our sales team for specific delivery estimates.

Are Anranst wear parts compatible with OEM MMD equipment?

Yes. All Anranst wear parts are manufactured to OEM dimensions with guaranteed interchangeability. We use CMM inspection against OEM drawings and provide full metallurgical traceability. No modifications needed for drop-in replacement.

MMD

MMD Sizer Teeth & Segments

MMD Mineral Sizers are the world's leading twin-shaft sizers, utilizing the unique principle of sizing by shear and tensile forces rather than compression. This produces less fines and better product shape. MMD sizers handle materials from coal to hard rock, with throughputs up to 10,000 tph. Anranst provides MMD tooth picks in both ZG30CrMnMo alloy steel and ASTM A128 Grade B-2 high manganese steel with verified chemical composition.

Maintenance Recommendations

costs are always key features in any mining operation, but are crucial in this abrasive, hostile environment, where the operation runs 24 hours per day. Varying the inlet length allows changes in capacity to suit the application. A typical 3 tooth machine, with twin 400 kW drives has an approximate mass of 160 tonnes.
