Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Grinding path liner
Forms a secondary grinding path and controls product fineness.
Grinding path liner (Grinding Path Liner)— Hammer Crusher Wear part, position 17.
Location and Function
| Material Options | Martensitic wear-resistant steel, high-chromium white cast iron, high-chromium/steel bimetal or ceramic/MMC composites |
| Typical Properties and Acceptance Criteria | The grinding path handles finer material after initial impact, with a greater proportion of sliding and compressive wear, so higher hardness may be suitable. Typical ranges are about 45–55 HRC for martensitic steel and 55–65 HRC for high-chromium working layers. Assess tramp material, edge impact and fastening-hole stresses. Control curvature, segment gaps, support faces, thickness and adjustment range. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; sliding and three-body abrasion, local 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.
