Jaw crusher elbow plate, in the process of crushing work, due to bear a great impact, extrusion load, poor working environment, and thus was strongly worn. It is not only a kind of vulnerable parts, but also an insurance part. In normal work, because the elbow plate and elbow pad can not be well lubricated, that is, the two can not form oil film. Moreover, dust falls into it. Therefore, there is a dry friction and abrasive wear between the elbow plate and the elbow pad. In this way, the elbow plate and elbow pad are worn very quickly, and the service life is very low. Therefore, extending the service life of the elbow plate is a very important task. In addition, the elbow plate and elbow pad pass a large impact pressure, in the case of repeated impact extrusion, elbow pad in the dynamic and elbow seat groove, extrusion deformation expansion, when it is difficult to remove the demolition.

Construction Waste Crusher elbow plate improvement measures have the following points:

1, variable sliding type is rolling type. The general board of swing angle less than 10 degrees, so this type of elbow and elbow pads for rolling head type, so as to realize slidinginto rolling, improve transmission efficiency, reduce wear and prolong its service life. 2. Change the lubricating fluid between elbow and elbow pad. The wear of elbow and elbow pad is influenced by the lubrication condition and dust. Practice has proved that the most effective way to improve the wear condition between parts is to lubricate the machine properly. In this way, not only can improve the machine efficiency, but also can prolong the service life of parts, and ensure the normal operation of the machine. For the jaw crusher elbow and elbow pad using lubricating oil, its lubrication effect is not ideal. Therefore, water lubrication can be used. The water can take away the heat produced by friction and wash away the dust, so as to prolong the service life of the elbow and the elbow pad. Adding water lubrication does not increase the auxiliary cost for the ore crusher, because the ore itself needs cleaning. 3. Adopt reasonable elbow and elbow pad structure. With the rolling instead of sliding on the viewpoint and the elbow pad for easy replacement and prolonging the service life, the elbow pad made of cylindrical, both ends of the square is fixed, when the side wear can change the other side, it can take turns 4 times, prolong the service life. The jaw crusher and the elbow pad overseas crusher have been used. 4, improve the elbow pad and elbow fit surface shape. The shape of the matching surface of the elbow pad and the elbow groove is changed into a trapezoid, and because of the slope of the fitting part, the elbow pad is worn in the groove of the elbow, and the elbow pad is easy to be pulled down even after the long time stamping deformation.
