Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Mantle
Forms the inner crushing face and defines the chamber together with the bowl liner.
Mantle (Mantle / Head Liner)— Cone Crushers Wear part, position 01.
Location and Function
| Material Options | Austenitic high-manganese cast steel such as Mn18Cr2 or Mn22Cr2; OEM-approved composite-reinforced high-manganese steel may be suitable for specific duties |
| Typical Properties and Acceptance Criteria | Key requirements are solution-treated microstructure, impact toughness, work-hardening in service and retention of the chamber profile. Verify chemical composition, grain-boundary carbides, casting defects, profile dimensions, mounting faces and lifting devices. High abrasiveness alone does not justify switching to brittle high-chromium white iron without validating the duty. Material changes also require assessment of feed grading, power, liner wear curves and cost per tonne. |
| Principal Failure Mechanism | Sliding or three-body abrasion, localized impact and cracking around fastener holes |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
