Jaw crusher is an important large-scale mineral processing equipment. During the operation, the wear of parts will seriously affect the vibration stability of the crusher. Some people have talked about the abnormal vibration of the jaw crusher. Indeed, when the jaw crusher is in operation, it may be subjected to such and such reasons as to cause the crusher to vibrate abnormally. Since it is abnormal vibration, then this is a kind of abnormal vibration. "Sickness" not only reduces the crushing performance of the crusher, but also shortens the service life of the machine. Therefore, we need to avoid the abnormal vibration of the jaw crusher during work. Let's take a look at how to prevent jaw crusher. The abnormal vibration of the machine!
1. Improve the installation base. A layer of rubber pad is sandwiched between the base of the jaw crusher body and the concrete for vibration reduction. The purpose of this is to reduce the large vibration. The machine base is not in direct contact with the concrete layer, which eliminates the disadvantage that the concrete layer is easy to wear, and the installation foundation will be firmer, eliminating the abnormal vibration caused by the loose foundation.
2. Fasten the parts in time. Check the firmness of each fixing bolt and anchor bolt. Once loose, it must be tightened in time to avoid falling off. Parts that are found to be severely worn must be replaced in time.
3. Ensure that the tightness of the V-belt is appropriate. If the transmission belt between the jaw crusher and the motor is too tight or too loose, the rotation of the flywheel of the jaw crusher will be abnormal, and the position deviation will cause the machine to vibrate violently. Therefore, it is necessary to ensure that the tightness of the V-belt is appropriate.
4. Reduce the swing pressure of the movable jaw. The large swing of the movable jaw will cause the jaw crusher to vibrate violently. In order to reduce the swing pressure of the movable jaw, a conveyor belt of the same size as the adjustment pad can be added between the adjustment pads as a buffer pad, and then the adjustment pad can be adjusted. The upper welding and repairing 2 pressure plates are used to prevent the adjustment pad from jumping out.
The abnormal vibration of the jaw crusher not only reduces the crushing performance of the crusher, but also shortens the service life of the machine. Therefore, we should try our best to avoid the abnormal vibration of the jaw crusher during operation.
