Impact crusher production in Shanghai what are the accessories, mentioned crusher production efficiency, it is easy to think of wearing parts is gold ore crusher, also can saying is accessories, spare parts or Shanghai SBM heavy crusher manufacturers to customers simple analysis, the first is the hammer of high-speed shift makes the material and the hammer plate and sieving slice, intense impact occurs between tooth plate, known as the material crushing. In the process of severe impact, the hammer plate will gradually wear out under the front impact of the material, and the impact effect and crushing effect will be greatly reduced, resulting in a decline in work efficiency. Secondly, the bearing is an important part to fix and reduce the friction coefficient during the working process. Because the machine runs at high speed, friction will not only increase the energy consumption of the metal crusher but also easily damage the bearing. Shanghai SBM heavy industry adopts pre-lubricated bearing, that is, with its own lubricating oil in the bearing. Crusher professional manufacturers, Shanghai crusher, yunnan crusher, please look for SBM heavy industry!
