Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Liner Backing Compound
Fills gaps, distributes loads evenly and prevents local loss of liner support.
Liner Backing Compound (Backing Compound)— Gyratory Crusher Wear part, position 23.
Location and Function
| Material Options | Two-part, 100% solids resilient epoxy composite for gyratory and cone crusher backing |
| Typical Properties and Acceptance Criteria | Requires low volumetric shrinkage, compressive load capacity, impact absorption, adhesion to steel and iron, and controlled exothermic curing. For example, the manufacturer gives a typical dry service range of approximately -28°C to 104°C for LOCTITE PC 9465. Final selection also requires checks of working time, curing temperature, pour thickness, removal procedures and safety data. |
| 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.
