Crusher can be divided into medical crusher and mining crusher according to large categories. The mine crusher is mainly used for crushing all kinds of stone materials. According to the different crushing principle and product particle size, it can be divided into many models. Crushers are widely used in mining, smelting, building materials, roads, railways, water conservancy, chemical industry and many other sectors.
The copper sleeve of crusher is equivalent to the bearing and plays the role of sliding bearing. The utility model has a copper sleeve, a large gear assembly is installed inside, and generally the wear is not much, and the total clearance is less than 5mm.
The bearing of the crusher bears all the load of the machine, so good lubrication has a great relationship with the bearing life, it directly affects the service life and operation rate of the machine, so the copper sleeve of the crusher must be wear-resistant.
The following quality commitments are made for the tin bronze crusher copper sleeve and other antifriction products produced by our factory:
1. When general large copper sleeve and copper sleeve products leave the factory, chemical composition, mechanical property report sheet and mechanical property sample are attached for the user's recheck;
2. NDT shall be carried out for key class I products to ensure that there are no defects such as internal cracks, slag inclusions and looseness;
3. The products used in large-scale cement equipment are produced by the most advanced low-pressure casting process at present. The characteristics of low-pressure casting, such as stable filling and solidification under pressure, are used to completely eliminate the defects of looseness, cracks and slag inclusions and obtain dense castings. Ensure that the surface is free of defects such as porosity and slag inclusion.
