What Shoud You Know About Jaw Crusher Machine?

Jaw crushers are invented in 1858 and first widely applied in road paving and then in mines. As one kind of stone crusher, it has many particular characteristics such as high crushing ratio, even product granularity, simple structure, reliable working condition, convenient maintenance and economical operation cost. The jaw crusher also called stone crusher in the mining industry. PE jaw crusher has the same advantages with stone crusher. It has wide application in many industries such as mines, metallurgy, building materials, highway, railway, water conservancy and chemical industry and the compression strength of the materials to be crushed should not exceed 320MPa.

The mobile jaw crushers have many kinds of structural types, but their working principle is the same, when they crush materials through the periodicity movement of the movable jaw. During the swinging process of the movable jaw to the fixed jaw around the hanging mandrel, the materials between the two jaw plates will be crushed, split and bent. In the beginning, the pressure is small, and the size of the materials will become small, and the materials will become closer and compacted; and when the pressure goes up to the degree that the materials cannot stand, and then the materials will be crushed.

On the contrary, when the movable jaw leaves the fixed jaw and swings to the opposite direction, the materials will fall under gravity. Every periodic movement of the movable jaw will give crushing effect on the materials and send them down a little. After several cycles, the crushed materials will be discharged out of the machine from the material discharging mouth. With the continuous movement of the electromotor and the periodic movement of the movable jaw of the crushing machine, the materials will be crushed and discharged, thus realizing volume production.
