What are the causes of jaw crusher shell damage?
The jaw crusher produced by our company is mainly divided into two kinds of coarse breaking machine used as a first-level crushing and fine jaw crusher used as a processing fine material. Its shell is reinforced, and it is difficult to cause damage if not operated improperly in the actual production process. But in the actual production process, it is inevitable that there will be some improper operation, resulting in damage to the jaw crusher shell, then what is the cause, the following Shandong Sanxiang Heavy Industry Co., Ltd. to do a simple analysis:
First: We all know that the main function of stone jaw crusher is basically to break larger pieces of material, the corresponding impact force of the equipment will increase, which will indirectly cause the phenomenon of cracking of the machine shell, one of the more important reasons is that the repair of the movable jaw plate and the fixed jaw plate is not in place, the excessive wear is not replaced in time, and the equipment will be replaced in a timely manner. Make the material more extrusion force feedback to the object part.
Second: the relevant skills of the jaw crusher are not in place. For example, there are obvious problems in the casting of the shell, welded jaw crusher shell in the welding of the relevant welding is not in place, in the actual production process of the machine, there will be shell cracking phenomenon.
Third: the strong bolts in the relevant parts of the jaw crusher appear to be loose and are not treated in time. Thousands of miles of mention in the ant nest, do not deliberately ignore every detail of things, machine maintenance must be in place.
Fourth: If the fixed jaw plate of the jaw crusher is not fixed, it will make the crusher appear continuous vibration in the actual production process, in the long run, the rated version will be more and more unfixed, it will continue to impact the front wall tooth plate of the frame, resulting in damage to the frame and the crusher shell.
Fifth: jaw crusher is generally equipped with a large size pulley, driven by its rotation of the pull of the moving jaw plate continues to do circular motion, but the screw above the pulley will also exist signs of loosening. If this phenomenon occurs, the large wheel will continue to show signs of deviation during the production process, which is easy to cause damage to the eccentric shaft of the machine and the relaxation of the expansion sleeve, and then cause the displacement of the flying-slot wheel counterweight in the direction.
Sixth: the bearing of the jaw crusher is damaged and not found in time, especially the bolt is not tightened or there are signs of loosening, for a long time, it will also damage the shell of the machine because of the abnormal movement.
Seventh: the initial installation base of the jaw crusher is not level, or later in the actual production of its base collapse and other phenomena are not repaired in time, will also cause excessive vibration of the machine, thereby causing damage to the machine shell.
Eighth: jaw crusher assembly elbow plate, shaft pad plate, tension spring and other parts of the quality is not qualified, can not withstand the huge pull brought by the machine production, so that the crusher in the strong impact can not play a good buffer role, resulting in damage to the machine shell is not impossible.
In summary, Shandong Sanxiang Heavy Industry Co., Ltd. according to many years of jaw crusher manufacturing and use experience, a preliminary summary of the easy to cause the shell damage of the 8 reasons, I hope you take as a warning. In addition, the cracking of the shell has a great relationship with the design and use of the method, only to regularly check the possible problems of the machine parts, timely replacement of the relevant parts, in order to maximize the service life of the machine.
