Counterweight Guard
Counterweight Guard / Liner
Identify parts for Metso cone crushers, check models and drawing numbers, confirm materials and processes, and submit an inquiry.
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.
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
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.
Hardox 400 Wear-Resistant Steel Plate
For abrasive dust exposure; verify hardness against the specific grade, thickness and material certificate.
High-Manganese Steel Mn13Cr2
For impact loading; heat treatment and acceptance hardness must follow the grade specification, drawing and technical agreement.
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
- High-velocity dust erosion causes uniform surface thinning.
- Occasional material impact causes localized dents.
- Airflow from the rotating counterweight carries particles that abrade bolt heads and edges.
Replacement Criteria
Assess replacement against the guard plate remaining-thickness limit in the drawing. Replace if wear penetrates the plate or extensive deformation occurs.
Materials and Processes
Materials, heat treatment, composite construction and inspection requirements depend on the specific drawing, operating conditions and technical review.
Material Grade / Substrate
Hardox 400 wear plate, Mn13Cr2 high-manganese steel, or wear-resistant steel plate specified by the drawing
Heat Treatment Condition
Specify heat treatment for the selected material. Verify final hardness and microstructure against the drawing and technical agreement.
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.
