METSO · Part Details
Mantle
Mantle / Head Liner
Identify parts for Metso cone crushers, check models and drawing, confirm materials and processes, and submit an inquiry.
Equipment and Applicable Models
Identify the installed machine model and key dimensions, then check the drawing revision and physical interfaces.
Models and Key Dimensions
Metso HP Series (HP100-HP800), GP Series (GP100-GP550) and Omnicone 1560
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
High-Manganese Steel Mn18Cr2
Solution-treated and water-quenched high-manganese steel; surface work hardening depends on impact and contact loading. Verify initial hardness against the material standard and drawing.
High-Manganese Steel Mn13Cr2
Standard manganese steel, a cost-effective option for medium-hard materials
Metso XT710
Specify independently manufactured replacement materials through the agreed specification, heat certificate and test results. Where an OEM commercial material is cited for identification, label it as an original-part reference and confirm ANRANST supply material separately without assuming equivalence or a life multiplier.
Metso MX composite wear material
A manganese steel matrix with wear-resistant inserts. Metso states that its MX for cones products can achieve up to 2 times the wear life of standard manganese liners under suitable conditions. This is not a service-life guarantee for parts supplied through this website.
High-manganese steel Mn22Cr2
Candidate high-manganese steel grade; suitability for a liner depends on the feed material, impact loads, chamber profile and drawing requirements.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- The lower mantle parallel zone typically wears fastest; its profile gradually flattens, affecting product size
- Material compression causes surface fatigue spalling, producing a fish-scale wear pattern
- Wear at the mantle-to-head mating surfaces loosens the installed liner
- Deterioration or failure of epoxy backing can cause liner loosening and fracture
Replacement criteria
Determine liner replacement timing from the maintenance manual and actual worn profile. Stop and inspect if product size cannot be corrected by CSS adjustment or if through-cracks appear. Clean mating surfaces, apply backing only where the design requires it, and tighten according to the model-specific procedure.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
High-manganese steels Mn18Cr2 and Mn13Cr2, Metso XT710 and other specified grades
Heat Treatment Condition
Solution heat treatment with water quenching. Final hardness and microstructure must meet the drawing and agreed technical specification.
Composite / Hardfacing Requirements
Metso MX composite liners use a manganese steel matrix with wear-resistant inserts rather than hardfacing. Replace the complete liner; localized repair is not applicable.
Dimensions and Inspection
Verify critical dimensions against the drawing for the OEM model details, including fits, sealing surfaces and oil groove locations. Select nondestructive testing methods for the material, part geometry and technical agreement; MT applies only to suitably magnetizable ferromagnetic materials. Check copper alloy bushing hardness and uniformity as specified in the drawing.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
