Jaw Crusher


 What is the jaw crusher ?

Jaw Crusher ( in China known as the tigers mouth ) is one of the first to be used for broken stone crusher equipment, appeared in 1858, Jaw Crusher was first widely used in road construction stone crushing, later used in mine. Because of its high crushing strength, uniform finished product size, simple structure, reliable work, convenient repair, operating costs and economic characteristics. Therefore, the jaw crusher were subsequently widely used in mining, smelting, building materials, highway, railway, water conservancy and chemical industries, especially for breaking strength less than 320 MPa various materials strong crusher.

As a leading manufacturer of whole set of crushing and screening equipment and a solution provider of aggregate production, Zhengzhou Yifan Machinery Co., Ltd., whose shareholder is Shande Technology(Beijing) Co., Ltd., can produce high-efficient and energy-saving crushing equipment. The mid-&large-scale jaw crushers are our premium products. In China, we reach the leading level on designing and producing large-scale jaw crusher. Jaw crusher is one of the common machines, used in the industrial and mining industry. It is mainly used as a primary and secondary crusher to crusher the material, whose compression strength is not more than 320Mpa. It has the features of simple structure, reliable operation, easy maintenance and low operation cost.

jaw crusher Applications:
This jaw crusher is mainly used in various industries, such as mining, smelting, road and railway construction, water conservation and chemical industry etc. The feed size of the crusher is less than 500 mm and the compressive strength of material to be crushed does not exceed 320Mpa

Jaw cruher principle:
This crusher adopts the electric motor as the power. The eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw following the preconcerted path to crush the feeding material. Thus the material will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. The material is discharged from the lower part of machine that is what you want. The motor transmits power through belt, drives the moving jaw do periodic motion to the fixed jaw surround the eccentric shaft. The angle between toggle plate and moving jaw increases when moving jaw moves up. So the moving jaw closes to the fixed jaw. The stuff will be crushed in this process. The angle of Jaw Crusher between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of rod and spring, the products after crushing will be discharged from the outlet of Jaw Crusher. The moving jaw crushes the materials periodically, which ensures the continuous production.

Jaw crusher Performance characteristics:
1. Simple structure, easy maintenance, reliable performance, large crushing ratio
2. Deep crushing cavity with no dead zone, which improves the capacity
3. Large crushing ratio, even product size
4. Adjustable discharge port—gasket-type, which is reliable and convenient. The big adjusting range ensures the flexibility.

Jaw crusher Structural characteristics:
The structure adopts high-strength manganese, and is cast and shaped at a time, which is of high resistance, high compression, and long service life. It is suitable to crush big, middle, or small stone or something like that.

The jaw crusher lubrication:
[1] .Board and board pad contact in the machine before, must add grease.
[2] .Often pay attention to timely lubrication friction surface, can guarantee the normal operation of the machine and extend the service life.
[3] .The machine adopts grease, should be based on the use of location, temperature and other conditions to determine, the general use of calcium, sodium or calcium sodium grease.
[4] .To join the bearing grease for the volume of the 40-70%, every three months to replace a; new oil must be used to clean gasoline or kerosene to clean the dirt in the bearing and the bearing seat.

Jaw crusher Special remarks:
Please carefully examine the fasteners, especially lubrication components and bolts, before the machine is started. Enough oil must be needed on each lubrication component. Fasten the loose bolts, clear the crushing cavity, and then start the machine. During the normal operation, even material feeding is important. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.

What is the JC jaw crusher , The development process of the JC jaw crusher:
JC jaw crusher is jaw crusher which a core R & D variety, is to introduce the most advanced international crushing technology and research results from Zhengzhou Yifan Machinery Co. , Ltd. Yifan million units jaw crusher on the basis of manufacturing experience , the use of finite element analysis method successfully developed a new generation of products .Well-known mining machinery crusher , sand making machine , mobile crushing plant and construction waste disposal equipment R & D manufacturer Zhengzhou Yifan Machinery Co., Ltd. launched a new crusher - JC hydraulic jaw crusher , which is the traditional jaw crusher technical upgrade of the machine , is currently the world's leading rock and mineral processing equipment . This series of jaw crusher , once put into the market by the hard , strong corrosive materials broken a warm welcome from industrial customers , has become the undisputed world's most popular jaw crusher .
