Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Grinding path spacer strip
Maintains grinding path spacing, supports liners and defines a controlled secondary crushing passage.
Grinding path spacer strip (Grinding Path Spacer Strip)— Hammer Crusher Wear part, position 18.
Location and Function
| Material Options | Quenched and tempered alloy steel, wear-resistant steel or a surface-hardfaced strip |
| Typical Properties and Acceptance Criteria | Spacer and grinding strips maintain grinding path geometry and material passages while carrying high local contact pressures and abrasive wear. Control cross-section, length, straightness, hardness gradient, fastening, end cracks and height relative to the liners. Changing strip height directly changes crushing clearance and product fineness. |
| Principal Failure Mechanism | Impact, cutting and abrasion |
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.
