Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Feed Hopper Liners
Absorbs falling ROM ore impacts and protects the feed hopper steelwork.
Feed Hopper Liners (Feed Hopper Liner)— Gyratory Crusher Wear part, position 33.
Location and Function
| Material Options | Quenched and tempered wear plate in the 400–500 HB range, bimetallic overlay plate, ceramic composite or rubber liners |
| Typical Properties and Acceptance Criteria | Material selection depends on lump impact and drop height, sliding distance, ore abrasiveness and blockage risk. Prioritise core toughness and replaceable modules in high-impact zones. In predominantly sliding zones, higher surface hardness or composite options may be suitable. Acceptance checks also cover plate thickness, bolts, joints, support and flow path geometry. |
| 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.
