Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Grate Segment / Screen Plate Segment
Provides a large open area and controls product size.
Grate Segment / Screen Plate Segment (Grate Segment / Screen Plate)— Hammer Crusher Wear part, position 13.
Location and Function
| Material Options | High-manganese steel, high-chromium cast iron or wear-resistant cast steel; OEM-specified heat- and wear-resistant cast steel for hot clinker or slag service |
| Typical Properties and Acceptance Criteria | Control grate opening geometry, curvature, plate thickness, mounting faces and segment matching. High-chromium materials resist abrasion but have lower impact toughness; high-manganese steel needs sufficient impact. Hot service also requires assessment of thermal fatigue, oxidation and thermal expansion. Judge wear from the effective opening area, remaining section and product size together. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; sliding and three-body abrasion, local impact and cracking around fastener holes; enlarged openings, blockage, erosion and fatigue |
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.
