The use of the scene shows that the wear layer on the broken roll surface is worn off very seriously, and some crushing teeth are broken. The wear layers on the surface of the crushing roller teeth nearly all wear off, and the wear is very serious. Nowadays, this kind of crusher has replaced hammer crusher, roller crusher, roller ball mill, etc. and become the mainstream equipment in sand making business. Domestic large-scale sizing crusher is mainly used for crushing hard materials with processing capacity, but it requires frequent maintenance and require.
There are two main reasons. First, the feed size is uneven. The larger portions of the material in the feed on broken teeth form strong impact resulting in the wearing off of the layer. Second, the choice of surfacing materials and surfacing method are unreasonable. There are cracks in part of the crushing roller tooth.
There are two main reasons. First, the structure design of the crushing roller teeth are reasonable, which leads the uneven force in the work and stress concentration. If there are other materials with large hardness in the feeding materials, the roller teeth will be broken. Second, the broken roller gear manufacturing process has defects. The sand holes and the accuracy of the process have great impact on the broken tooth.
After materials are fed into the hopper, they are through a central feeding hole, thrown to the impellers, which are rotating at a high speed. Then the material are accelerated and thrown out of impeller area. There part of materials, first, impact on the other part of materials, which are falling down, and then, they together strike on the material layers or on impact blocks. Due to rebound, they will back to top of crushing cavity and again be shot back to strike on another part of materials which are shot from the impeller flow and form a continuous material curtain.
The final products will be discharged from the discharge open at the bottom. In the application, you should often check the lubrication of the crusher. Lubrication is very important for crusher, add grease periodically to ensure the normal operation of the crusher and increase the service life. Otherwise, check the crusher spares and parts. The sizing crusher produced by Henan Hongxing Mining Machinery is designed by reputed German expert of Hongxing Mining Machinery and every index of SBM VSI crusher is in world’s leading standard. SBM VSI crusher incorporates three crushing types and it can be operated 720 hours continuously.
