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
Material option for standard chamber liners, with work-hardening capability after solution treatment and water quenching
Metso XT710
Metso proprietary manganese alloy designed to balance wear resistance and toughness
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.
Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- The parallel liner zone typically wears fastest, affecting product size
- The feed zone wears more slowly, but its condition affects material distribution and throughput
- Distortion of the liner profile through wear reduces crushing efficiency and increases power consumption
Replacement Criteria
System maintenance: 1) Plan matched mantle and concave replacement for the chamber profile and wear condition; 2) inspect mating surfaces for wear; 3) schedule maintenance using product size monitoring; 4) follow the model-specific maintenance manual for run-in, fastener checks and loading after replacement.
Equipment, Models and Drawing References
Identify the installed machine model and key dimensions, then check the part number, drawing number, drawing revision and physical interfaces.
Equipment Series
Metso Cone Crushers
Models and Key Dimensions
Metso HP series (HP100-HP800), GP series (GP100-GP550), and MP series (MP800-MP1000)
Drawing Number / Part Number
See the OEM part number table below
Provide the equipment nameplate, complete model and existing part number so that the installation position and drawings can be checked.
Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
Materials and Processes
Materials, heat treatment, composite construction and inspection requirements depend on the specific drawing, operating conditions and technical review.
Material Grade / Substrate
High-manganese steel Mn18Cr2, Metso XT710 and Metso MX composite materials
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
Manufacture to drawings produced from part measurements or supplied by the customer. Critical mating surface tolerances follow OEM requirements. Use UT/MT inspection to assess castings for shrinkage porosity and cracks against the agreed acceptance criteria.
Parts with the same name may not be interchangeable because of differences in machine model, drawing revision, mounting interface or material specification. Use the complete model, serial number, drawing number and drawing before manufacture.
