Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Mantle
Forms the moving crushing face and works with the concaves to provide continuous compression crushing.
Mantle (Mantle)— Gyratory Crusher Wear part, position 03.
Location and Function
| Material Options | Austenitic high-manganese cast steel such as Mn18Cr2 or Mn22Cr2; OEM-approved composite-reinforced high-manganese steel may be used after validation for the duty |
| Typical Properties and Acceptance Criteria | Typical Mn18/Mn22 high-manganese steel may contain approximately 1.0–1.4% C, 17–23% Mn and 1–2.5% Cr. Initial hardness after solution treatment is commonly around 180–240 HB and may rise to around 400–550 HB through work-hardening under impact and compression. Acceptance checks focus on chemical composition, grain-boundary carbides, impact toughness, shrinkage cavities and slag inclusions, profile, mounting faces and lifting devices. A single hardness reading cannot predict service life. |
| 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.
