Swing Hammers
Key Wear Parts for Coal Impactor
Swing Hammers (Swing Hammer)— Coal Impactor Wear part, position 01.
Location and Function
| Installation Position | At the rotor periphery, mounted on suspension bars between the suspension discs |
| Function | Directly strikes coal during high-speed rotation and throws material toward the breaker plates. |
- Recommended material: tough forged alloy steel with differential heat treatment (differentially heat-treated forged tough alloy steel).
- Confirm the grade, hardness and chemical composition against drawings; do not assume ZGMn13Cr2, Cr26 or a fixed HRC value. Specify the model, drawing, unit weight, heat treatment and impact duty for procurement.
- Confirm material and manufacturing requirements against the specific model, drawings and acceptance agreement.
Information Required for RFQ
- Obtain the equipment nameplate, model, serial number, original model details, drawing revision, used-part dimensions and failure photographs. Record coal properties, maximum feed size, moisture, gangue or tramp metal, throughput, speed, clearances, vibration 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.
