Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Grate basket trolley rollers and guides
Supports grate basket withdrawal, reinstallation and positioning for grate maintenance.
Grate basket trolley rollers and guides (Grate Basket Trolley Roller and Guide)— Hammer Crusher Wear part, position 15.
Location and Function
| Material Options | Materials such as 42CrMo/C45 for axles and surface-hardened wheels, wear-resistant guide steel and rolling-bearing steel |
| Typical Properties and Acceptance Criteria | Trolley parts must carry the grate basket weight under contamination, uneven loading and low-speed rolling contact. Control wheel diameter, tread hardness, bearings, axles, guide straightness and parallelism, locking and load distribution. Local hardfacing must not cause tread spalling or uneven guides. After maintenance, verify the operating-position lock and safe rotor clearance. |
| Principal Failure Mechanism | Impact, cutting and abrasion; contact fatigue, surface wear, thermal cracking or spalling; aperture enlargement, plugging, 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.
