What wear parts are available for Metso SAG/AG Mills?

Anranst supplies complete wear parts for Metso SAG/AG Mills, including jaw plates, cone liners, blow bars, and other critical wear components. 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 Metso SAG/AG Mills 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 Metso SAG/AG Mills 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 Metso 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.

SAG/AG Mills

Name: SAG/AG Mills — Metso
Brand: Metso
Availability: InStock

Metso SAG/AG mills are the workhorses of modern mineral processing. With diameters up to 40 feet, these mills process run-of-mine ore in primary grinding circuits. Metso's patented Poly-Met liner system combines rubber and metal for maximum throughput with reduced weight. Anranst supplies complete SAG mill liner packages including lifter bars, shell plates and grate panels in Cr20/Cr26 high-chrome iron and Mn18Cr2 alloy steel.

Typical Applications

Coppergoldiron oreand other metal ore grinding circuits.
