Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Rotor Protective Liner
Prevents rebounding material and fines from wearing the rotor body directly.
Rotor Protective Liner (Rotor Protection Liner)— Impact Crusher Wear part, position 05.
Location and Function
| Material Options | Martensitic wear-resistant steel, high-chromium bimetal, wear-resistant cast steel or ceramic composites |
| Typical Properties and Acceptance Criteria | Protects the non-working surfaces of rotor discs and blow bar seats. Balance resistance to fines erosion and chipping with reliable fastening and ease of removal. High-chromium or ceramic composites may improve life in steady abrasive duty, but edges and bolt areas need protection. Validate performance with site wear consumption per tonne; a manufacturer's life improvement percentage applies only to the stated test or case. |
| 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.
