Hammer crusher common fault solution and safe operation procedures

Hammer crusher under the operating process to withstand the moment or vibration, often cause the transmission system failure, common are: bearing room, bearing bit wear, pulley hub, shaft head, keyway wear and so on.
After the above problems occur, the traditional maintenance methods are mainly repaired or repaired after brush plating, but both have certain drawbacks. The thermal stress generated by the repair welding can not be completely eliminated, which may cause damage to the material and lead to bending or fracture of the components. The brush plating is limited by the coating thickness and is easily peeled off. The above two methods all use metal to repair metal and cannot be changed. The “hard-to-hard” cooperation relationship will still cause further wear and tear under the combined effects of various forces. The above-mentioned maintenance methods are not common in Western countries. Contemporary European, American, and other developed countries use the repair methods of polymer composite materials to solve the above problems. The most mature technology is the 1stline technology product, which has superior adhesion and excellent performance. Compressive strength and other comprehensive performance, can be disassembled, free machining for on-site repair. The use of polymer materials for repair has no effect on the thermal stress of the repair welding, and the repair thickness is not limited. At the same time, the metal material possessed by the product does not possess constancy, and can absorb the impact shock of the equipment, avoid the possibility of re-wear, and greatly extend the equipment components. The service life of the company saves a lot of downtime and creates great economic value.
Hammer crusher safety operation regulations:
1. During the inspection, labor protection products must be properly worn and carefully taken care of.
2. Regularly check the wear condition of the hammerhead, observe whether the hammerhead has cracks, and whether the hammerhead connection is vibrating.
3. The particle size of the broken material in the crusher shall not exceed the maximum particle size of the specified material.
4. Observe the operating sound of the crusher, check whether the hydraulic and lubrication systems are normal, and find that the abnormalities are timely contact with the central control, take corresponding measures according to the situation and report to the superior leaders in time.
5. Regularly inspect the protective cover of the drive belt and coupling for looseness and looseness of the anchor bolt. Otherwise, tighten it in time.
6. Regularly check the temperature and sound of the bearing, the vibration of the body, and notify the relevant personnel to check the abnormality.
7. When the equipment is in operation, the crusher will have abnormal broken sound, stop immediately, and inform relevant personnel and supervisors to carry out detailed inspections.
8. Observe whether the discharge pit exceeds the size required for the feed particle size. If it is found, it shall be immediately stopped by the plate feeder.
