Jaw crusher installation should note the following: (1) Since the jaw crusher vibration greater machine at work should be mounted on a concrete foundation, in order to reduce vibration, noise, and to nearby built structures based on the influence of wind election grading machine, 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. Grader, should release the T-line adjustment bolts and tension springs. 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, when the spring preload adjustment to ensure that the machines work so that the thrust plate and thrust plate pad close. But pre-pressure should not be too big a wet classifier, 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, it is the first choice for the majority of users of broken machinery equipment. Jaw crusher operation common major fault summarized as follows: (1) crusher idling, the lower metal crash occurs. When the jaw crusher work load, the lower metal crash may occur due to the following three aspects: ① mobile jaw and fixed jaw broken tooth plate colliding sound is too small because the port of discharge caused, should be timely adjusted. ② thrust plate supporting or shims percussion device appears, generally due to the buffer spring elastic rod disappears or damaged, or does not bear the weight of the spring caused by rotation of the movable jaw plate bracket when combined with the body of the three does not close, make bracket head and have a knock-supported at both ends, or adjust shims hit each other several rounds of inter-grader, compression nut should be tightened until the crash disappeared. ③ There may be badly worn bearing slide bracket or loose brackets serious head wear, should be replaced. (2) work with metal percussion, backing jitter. This phenomenon is more due to the crushing chamber side lining and the tooth plate (dynamic, fixed) are loose, tighten loose screws or broken due to, should be tightened or replaced. (3) after the brackets break frequently. In addition to transfer power after the brackets outside still live on less than its strength from the insurance role. In addition to the strength of the middle bracket is too low, it is not strong enough to overcome the normal crushing ore crushing force generated by damage, this may be overextended rod spring, plus the work force to crush when it overload fracture, may be appropriate loosen the spring. (4) rotating flywheel, the crusher is not working. The reason is because of the spring rod and rod damage, rod nut from coming out of the trip to make the bracket bearing slider, or it may be broken off bracket, you should replace the installation. (5) flywheel significant swing, eccentric shaft rotating slowly. The fault line belongs to the pulley and flywheel key loose or damaged, the wheel can not be synchronized with the axis of rotation. (6) of the crushed product size thicker, the result is the lower part of the broken liner serious wear and tear. Tooth plate should be exchanged or replaced under the new liner, adjust the port of discharge required size.
