Jaw crusher is used most of the time the initial ore crushing, precisely because it is a large feed size, so indispensable in a large stone production line, jaw crusher is simulated human jaws movement of material crushing operations medium grain size typically used in mining, building materials, railway, highway, metallurgy, water conservancy and chemical industry in a variety of ores and bulk materials broken. 

    Jaw crusher is generally not prone to clogging failure, because of its large feed, the material is relatively large, which does not mesh grate, so plugging failure is rarely arise. But whether it has reached the limit of any device in the production of various failures are likely to occur, jaw crusher is no exception, and the face of these failures also must be handled with care, if not handled properly will not only affect the jaw crusher productivity, can also cause serious accidents. Therefore, during the processing of jaw crusher blockage must pay attention. If a large number of ore resulting in a jam in the crushing chamber, then it should first turn off the power to stop working, clean-up materials will be blocked after work clean. It should be noted here is that no matter what the situation is absolutely prohibited removed by hand from the ore crushing cavity between the jaws, or you can use a crowbar, hooks and other tools to deal with. 

    It's good lubrication for maintenance and repairs in the process of jaw crusher, you can reduce the clogging phenomenon, but also can reduce the wear and tear of the equipment, thus prolonging the life of the jaw crusher.
