Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Rotor Assemblies
Carries the blow bars, stores rotational energy and converts drive torque into impact crushing energy.
Rotor Assemblies (Rotor Assembly)— Impact Crusher Wear part, position 04.
Location and Function
| Material Options | High-strength low-alloy cast steel, a welded forging assembly or high-strength welded structural steel; blow bar seats to the OEM design |
| Typical Properties and Acceptance Criteria | The rotor is critical to safe operation at high speed and heavy load. Control base material yield and tensile strength, low-temperature impact toughness, internal casting or forging quality, welding procedure qualification, blow bar slot geometry, mainshaft fit, circular runout, and static and dynamic balance. Crack repairs, hardfacing or structural changes require engineering review and NDT. Surface welding alone does not establish a sound repair. |
| Principal Failure Mechanism | Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism |
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.
