After using the mining crushing equipment,a lot of customers encountered such a problem, why the actual service life of wearing parts can not reach the expected service life, and which is causing the problem?First, non-standard installationMost of the hammer heads inside the crusher are operated according to the circular track. If the equipment is tilted during installation, the trajectory of the hammer in the interior of the device changes, which will increase the load of the hammer head and reduce the service life.Second, irregular feedingEach crushing device has its own unique feeding size. For example, the feeding size of the PE600*900 jaw crusher is 480mm. If a material greater than 480mm enters into the equipment, which will not only damage the jaw plate, but also cause blockage and ...
