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 Mn13Cr2 / Mn18Cr2
A conventional wear liner material for positions exposed to impact loading
Hardox 400/500 Wear-Resistant Steel Plate
For positions exposed mainly to dust erosion and sliding wear; verify hardness against the specific grade, thickness and material certificate.
Wear-resistant steel plate specified by the drawing
Select materials and surface treatments for lightly loaded positions according to the drawing and actual wear conditions.
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
- Wear mechanisms differ by position: arm guards primarily experience impact wear, while counterweight guards primarily experience dust erosion.
- Worn liners expose the main frame metal and can cause permanent structural damage.
- Worn bolt heads create a risk of liner detachment.
Replacement Criteria
System maintenance: 1) Measure liner thickness regularly and plan preventive replacement; 2) Inspect the underlying main frame for wear when replacing liners; 3) Follow the model's assembly requirements for fasteners and locking measures; 4) Use backing material only at positions specified in the drawing.
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
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
Mn13Cr2 / Mn18Cr2 high-manganese steel, Hardox 400/500 wear plate, or wear-resistant steel plate specified by the drawing
Heat Treatment Condition
Follow the applicable standard for the material grade; confirm heat treatment and hardness requirements against the drawing
Composite / Hardfacing Requirements
Weld Hardox wear plate using an approved procedure for the grade and thickness. Select consumables, preheat, interpass temperature and repair limits in accordance with the manufacturer's recommendations and the drawing.
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.
