The jaw crusher is a kind of widely used coarse crushing equipment with big inertia force, poor working conditions and heavy-duty work. In order to ensure the normal continuous operation of the jaw crusher, giving full play to its production capacity, except for the proper operation, the regular maintenance and periodic repair is needed for the jaw crusher. In addition, it is a necessary skill for the stuff to find and eliminate the possible failure of jaw crusher accurately and timely.

In our routine work, the most frequently used crusher in ore dressing plant or stone plant is jaw crusher. Compared with other crushers, jaw crusher has the advantages of low cost and high efficiency. Due to the fact that wear-resisting requirement of jaw crusher is quite high, so the material is usually high wear-resisting manganese steel lining plate. There are two jaw plates in crushing chamber; one is fixed on the upside of crusher; the other is mobile and forms a crushing chamber with the fixed jaw plate.

The mobile jaw plate repeatedly moves towards the fixed jaw plate. When two jaw plates separate, material immediately is put into crushing chamber. At this moment, the crushed material is discharged from the bottom of crusher. When the two jaw plates are close, material is crushed by buckling and split function caused by the acting force of extrusion and rub of two jaw plates.

In jaw crusher, the motor drives the belt and belt pulley to make the movable jaw move through the eccentric shaft. When movable jaw is rising, the included angle between the wrist plate and movable jaw plate become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing;
