The jaw crusher is also called jaw crusher machine,primary crushers,primary jaw crusher or tiger mouth. The crushing cavity of the jaw crusher is made up of dynamic jaw board and static jaw board and finishes the crushing process by simulating the movement of animal jaws. Jaw crusher is widely used to crush medium sized granularity of different ores and bully materials in mining, metallurgy, building materials, highway, railway, water conservancy and chemical industries. The highest compressive strength of the crushed materials reaches 320Mpa.
1. Effectively solves the problem of high operation rate and little maintenance time caused by low output of limestone crusher.
2. Can complete the crushing work of large-sized limestone.
3. The blending of the two materials is even and the mixing quantity of the desulfurized limestone is greatly increased.
4. The electricity needed is reduced.
5. The granularity of the wastes is small.
6. Effectively improves the labor strength and the working environment of the workers.
It is widely used in fields of ore crushing, construction aggregate production, construction waste crushing, water conservancy and Hydropower Engineering, highway, railway, road and bridge construction and other industries. It is suitable for granite, marble, limestone, basalt stones and so on. PE series jaw crusher is known as the European version jaw crusher, which is a new type of crusher of my company following traditional jaw crusher. The product is a perfect combination of modern technology and production practice, which is more in line with the majority of customersâ€™ requirements about automation production.
The dynamic jaw moving from side to side is hung on the mandrel. When the eccentric shaft is turning, its connecting rod moves up and down, which also drives the two thrust plates to do the same movement. Then the dynamic jaw moves from side to side to realize crushing and unloading. The jaw crusher adopts crank link mechanism. Although the dynamic jaw bears great broken counter-force and the eccentric shaft and the connecting rod bears little stress, industrial enterprises usually make large sized machine and middle sized to crush hard materials. Additionally, every moving track of the dynamic jaw is an arc with the mandrel as its center. The circular arc radius equals the distance from the point to the axis with the upper arc being smaller and the lower arc bigger. The crushing efficiency of the jaw crusher is quite low and the crushing ratio is 3-6.
