Jaw crusher installation should note the following: (1) Since a large jaw crusher vibration at work, the machine should be installed in the concrete foundation miniature grader, in order to reduce vibration, noise, and to nearby built structures foundation the impact between the crusher and concrete base mat with hardwood plate, a rubber band or other cushioning material. (2) Basic of discharge trough to lay a metal plate, and has sufficient inclination angle (depending on the flow of materials should be determined, not less than 50 °), so as not to impede the smooth discharge of the crushed product. (3) nesting population size should be required to adjust the particle size. When adjusting, loosen the bolts and tension springs T lines. Use a bolt from the top to adjust the seat to open the top, insert or removing the appropriate thickness shim, then return from the top bolt, adjust the seat under the action of gravity moving jaw, ear close to the seat frame, while the spacer group pressure rope together. Thereafter grading machine, adjust the spring preload to ensure the machine work wet classifier, so that the thrust plate and thrust plate pad close. But pre-pressure should not be too large, it does not happen percussion, finally locking seat adjustment. Our company specializes in the production of jaw crusher (broken jaw or broken jaw), widely used in the quarry, concentrator, building materials factory and many other areas of production rounds grader, it is the first choice for the majority of users of broken machinery equipment. Brief Description ball mill grinding mill flow principle 1, feeding method, the material is the first to enter the innermost trajectory, and only rely on centrifugal force and the material constantly fed circular motion of the material in the grinding gap gradually to the sport outer trajectory, in the end mill run some distance before movement into the outer track. 2, the trajectory of the ball is the inner layer, grinding smaller role, coarse particles can not be effectively broken, it is enriched with a lot of coarse particles. In cross section mill, the material from the grinding capacity at the weakest to the strongest movement, coarse material is difficult to move to the grinding capacity of the strongest outer material distribution is unreasonable, is not conducive to the grinding mill ability to play. 3, coarse grinding mill warehouse deafening sound on the other hand also shows that the outer layer of the strongest in the grinding lack of cushioning material, producing a large void between collisions resulting in grinding and grinding bodies and linings, consumption a lot of kinetic energy into sound energy and heat dissipated to do is exercise in futility. Coarse grinding of materials in the warehouse track gradually moved from the inner track outwardly process, once close to the outer tracks have simplified certain material, the material in the track is more than sufficient to enable the mill sports out of balance, resulting in "full mill" took place .
