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
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 Mn18Cr2
Wear-resistant option for highly abrasive feed materials
Hardox 500 Wear-Resistant Steel Plate
Confirm Hardox 500 hardness for the specified thickness against the material certificate. It is a candidate material for sliding abrasion.
Alloy steel 42CrMo4 with surface hardening
Forged option; verify the hardened surface layer and core toughness against the specific part drawing.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Feed impact causes wear and deformation at the top of the feed cone
- Uneven loading accelerates wear on one side of the feed cone, further worsening feed distribution
- A worn feed cone can direct material to one side of the crushing chamber, causing uneven liner wear
Replacement criteria
Assess remaining feed cone height, thickness and uneven wear against the maintenance manual. Inspect the feed cone when feed distribution becomes uneven or uneven liner wear increases. Use the model-specific wear limits to decide on replacement.
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 Mn13Cr2 and Mn18Cr2, Hardox 500 wear plate and other drawing-specified 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
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
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.
