The degree of wear of the movable jaw tooth plate is not only relate to the physical mechanical properties, tooth plate shape, crushing parameters, but also closely related to the motion trail.
Motion Trail of Each Point in Tooth Plate
According to the figure, we can conclude that the trail of the tooth plate has a big difference for the different heights of crushing chamber. In the upper part of the crushing chamber, is approximately elliptical trail, while in the lower part of the crushing chamber, is approximately an extremely stretched elliptical trail. Discharge end of compound pendulum jaw crusher has big motion value,that is to say there is a large stroke in vertical direction,which is benefit to discharge wet materials. But the large stroke in vertical direction will make longer slide time for materials which causes more wear in tooth plate. In order to improve the moving jaw tooth plate abrasion and improve the life of the tooth plate, we should choose the most suitable parameter, what is more important is to change the motion trail to control the wear situation of tooth plate.
