The working principle of sand and gravel crushing equipment is special, so it needs to be equipped with a reducer when working. During use, the reducer will inevitably have some failures. How to solve these problems correctly? If it is found that the air vent of the reducer of the gravel crushing equipment is blocked, it should be removed immediately and replaced with a gas cleaning filter.

During the inspection, it was found that the oil pressure, oil temperature and flow data of the reducer of the gravel crushing equipment were abnormal. The filter and nozzle must be cleaned. After cleaning, check whether the lubrication is used normally. For the bearings of the reducer of the gravel crushing equipment, when reinstalling and reassembling, it is necessary to add an appropriate amount of calcium-sodium grease for lubrication, which is about one-third of the volume of the bearing space.

When the tooth surface damage area exceeds 20% in the tooth length direction and the tooth height direction, the gears should be replaced in pairs. After replacement, the gear should be run and load tested. The tooth length contact rate is as high as 60%, and the tooth is as high as 100%. It can only be used officially within 40 minutes. When working on gravel crushing equipment, if the oil temperature of the reducer exceeds 80 degrees or the temperature of the oil pool exceeds 100 degrees, or abnormal noise is generated, please stop using it. Check the cause and troubleshoot the operation. When the reducer rotates, the output shaft does not rotate. The reducer key connection may be broken and the reducer needs to be removed.

According to the manufacturing process, the hammer head can be divided into casting hammer and forging hammer. According to the material, it can be divided into high chromium hammer, composite hammer, high manganese steel hammer, cemented carbide hammer. Each material has its own advantages and disadvantages, as well as its own characteristics and functions. For the sorghum alloy breaker, its hardness is excellent, but its toughness is poor. Without the support of the hammer frame, it is easy to break. High manganese steel hammer has good toughness, good manufacturability and low price, but high. The manganese steel hammer has high requirements for the overall performance of the sand and gravel crushing equipment. If the physical impact force is insufficient or the contact stress is small in actual work, the surface cannot be quickly produced and hardened, so it cannot exert its proper wear resistance; sand and gravel crushing equipment is a production process used in product production. It combines toughness and wear resistance. It not only makes the hammer handle part resistant to impact, but also makes the hammer head part wear-resistant; compared with materials, cemented carbide hammers have higher hardness, bending strength, impact resistance, and thermal fatigue resistance.
