Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Impact wall liner
Provides a fixed impact surface and protects the housing.
Impact wall liner (Impact Wall Liner / Breaker Plate Liner)— Hammer Crusher Wear part, position 16.
Location and Function
| Material Options | AISI 1040/1045 carbon-manganese steel, manganese steel, martensitic wear-resistant steel, high-chromium white cast iron or composites |
| Typical Properties and Acceptance Criteria | Impact wall liners withstand rebounding material and abrasive wear. TerraSource lists hot-rolled 1040/1045 carbon-manganese steel for TKK breaker plates. Higher hardness may be considered in abrasive zones, but toughness remains essential under lump impact and around holes or thin sections. Inspection covers flat or curved profiles, thickness, hole positions, fit, composition, hardness and cracks. |
| 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.
