How to extend the service life of jaw crusher
Time：2020-08-28 Writer：ZhongXin
First of all, the material selection: the material of the crushing plate can be white cast iron. White cast iron has higher hardness, better wear resistance, easy source, and low price; the disadvantage is that it is brittle, easy to break, and has a short service life. In order to improve the service life of the crushing plate, it is better to use manganese steel with a manganese content of more than 12%, and the comm used one is ZGMn13. The disadvantage of manganese steel is that it is more expensive, but from the overall consideration of service life and cost, ZGMn13 has a service life and lower cost than white cast iron.
Finally, there are precautions during use: the crushing plate acts directly on the material, and the crushing force is very large, especially when crushing materials with high hardness, it will cause the bolts of the crushing plate to vibrate and the nuts to loosen, which will increase the wear and tear of the crushing plate. Extreme noise, when the crushing plate falls off or breaks, the equipment will s and affect normal production. In this case, just tightening the bolts and nuts before starting the machine can not solve the problem. It is necessary to analyze the specific problems according to the actual situation on the spot, and find ways to solve the problem in practical ways.
