Duma Machinery Technical Tips: There are several ways to effectively extend the service life of crusher hammers:
1) According to the design model, appropriately control the feed size. Strictly prohibit materials exceeding the maximum design size from entering the machine to avoid excessive impact on the crusher hammers. 2) Choose appropriate feeding equipment, such as plate feeders or vibrating feeders, to ensure stable and uniform feeding. Avoid uneven feeding causing impact and inefficient operation, thus affecting
wear and tear. excessive impact on the crusher hammers. 3) Due to casting quality variations, high-manganese steel or high-chromium hammers should be replaced in a timely and appropriate manner during use to ensure even wear and balanced rotor operation.
4) When replacing new
hammers, weigh them and divide them into groups of equal weight. Unequal weights will cause rotor imbalance, leading to vibrations during startup and reducing the lifespan of the crusher hammers. excessive impact on the crusher hammers. 5) When stopping, check the clearances between the hammers and the screen bars, and between the screen bars and the screen mesh. Adjust as necessary and replace the screen mesh regularly. Since hammers are more expensive than screen bars, new hammers can last 4-5 times longer than old ones.
6) The hammer frame is made of cast steel and has less contact with the material. However, if metal objects enter the crusher or the liner plates fall off, it can damage or bend the hammer plates. Replace them promptly to prevent
vibrations and loss. excessive impact on the crusher hammers. 7) The hammer frame side plates and chassis sides are severely worn due to material impact. To extend the service life of the side plates, a wear-resistant layer can be welded to the surface of the side plates and the circumference of the side near the plates.
8) Due to friction, the ends of the main shaft are prone to wear. Install two bushings on the shaft diameter to protect the shaft.
9) Repair and adjust worn bearings promptly. Worn bearings should generally be reground to new dimensions, and the thickness of the shims adjusted to leave a reasonable clearance for effective lubrication.
10) The power and speed of the rotor are directly related to the crusher's production capacity and the impact force of the hammers. The hardening degree of the hammers and material type are important for extending
lifespan. For high-manganese steel hammers, ensure sufficient impact force; for high-chromium steel hammers, control the impact force to avoid excessive force. excessive impact on the crusher hammers. 11) Choose high-quality castings to ensure the durability of high-manganese steel or high-chromium hammers.
11）选择能保持质量的优良铸件，确保高锰钢材质锤头或高铬材质锤头的耐用性。
