The structure of jaw crusher: main frame, eccentric shaft, a large belt pulley, fly wheel, swing jaw, side guard plate, toggle plate, Rear bracket, adjust gap screw, reset spring, and fixed jaw and swing jaw board etc., and the toggle plate also plays a role of protection.So we can say that the structure of jaw crusher is relatively more simple as compared with other types of stone crusher. And it is useful to crusher all sizes and all kind of materials. With the excellent performance, it is important for construction and mining industry.

Due to the simple structure, jaw crusher is easy to maintain and repair. These features promote its popularity to a great extant.Even the jaw crusher is made from selected materials, the wear is inevitable. The operators should be aware of how to inspect the worn parts and how to replace them. When it comes to the purchase of parts of jaw crusher, your loca retail stores would be able to meet your requirements since the crusher is so popular. The operation is not so difficult, even though the jaw crusher seems to be heavy and ponderous. While being operated by qualified operators, the movement of jaw crusher seems to be flexible and convenient.

Its operations are as following:

First, after the start, if the crusher makes unusual knock, you should stop the machine. After identifying and eliminating the ills, you can restart the machine.

Second, the crusher must start without load. After the normal operation, you can open the mining equipment. The feeding ore should be increased gradually.

Third, the feeding should be even. The ore is not allowed to pack with the crushing chamber. The maximum size of the feeding ore should not be more that 0.85 times greater of the width of the feeding mouth.

Forth, in the operation of the crusher, when too much ore blocks the crushing cavity, do not stop the machine. You should stop feeding ore. You should regularly check the crushing cavity. Fifth, do not immediately stop the machine when the temperature of the bearing is too high. At this time, you should increase the amount of oil.

Our range of High-efficiency Fine Crusher is designed by our engineers based on introducing advanced technology of this field and combining with different working conditions of international cement industry, mining, beneficiation, building material and so on. High efficiency fine crusher is also called high efficiency fine impact crusher which is a kind of impact crusher in theory. It improves the fineness of discharging granularity by improving the rotation speed and equipping the grid section device.

By taking the advantages of hammer Crusher and Impact Crusher , this machine can highly improve working efficiency and reduce energy consumption. High-efficiency Fine Crusher which has significant advantage in the field of crushing soft material features reliable operation, simple structure, convenient maintenance, high capacity, long service life.

This kind of high efficiency fine crusher has very wide application and its performance has reached to the international advanced level. Therefore, it is the most efficient, practical and reliable crushing equipment in current situation, especially for the fine crushing and medium crushing of many kinds of hard and brittle materials like grinding materials, fireproof materials, cement, quartz sand, steel grit, concrete aggregate and copper ore, etc.

This type of fine crusher can save 50% energy compared with the traditional fine crusher, it is a kind of high efficiency and energy saving sand making machine which is also the most advanced fine crushing equipment in the world. HXJQ high efficiency fine crusher has the following characteristics:

1.The distance between discharging grates and rotor can be adjusted. It enjoys steady discharging granularity.

2. The high efficiency fine crusher has long service life and it is easier to adjust and the safety performance is higher.

3.Stone high efficiency fine crusher with high yield and the product is small in size.

4. The discharging granularity of high efficiency fine crusher can be adjusted randomly according to the practical needs.

5.The crushing cavity enables the wear-resistant parts to have longer service life.

6. The high efficiency fine crusher adopts the elastic constant force adjustment which makes the crushing constant force invariant.

7. The hydraulic device is convenient to maintain.

8. Compared with hammer crusher and impact crusher, only the rotor on the high efficiency fine crusher may abrade and the wheel core and hammer carrier will not be abraded.

JC series jaw crusher is designed by our company--Henan Hongxing Mining Machinery Company, which is a joint-stock mining machinery manufacturing enterprise integrating in science research, production and marketing in the High & New Technology Industries Development Zone of Zhengzhou. JC series jaw crusher is based on Hongxing's experts in designing and conception and absorbs top crushing technology and research results in the world.

It has robust structure.There are two types of machine frame: welded model and assembled model. The former is for small and middle size, and the latter is for big size.In addition, JC series jaw crusher has the optimized cavity structure.The whole set of heavy movable jaw plate is durable. What's more, JC series jaw crusher has the protective planch of movable jaw plate. Heavy protective planch installed above the movable jaw plate protects internal bearing from damage caused by material falling down in feeding moment. It also owns one piece cast of bearing seat.One piece cast of bearing seat assures good match with frame, and avoids unnecessary radio direction press for bearing in fastening process which occurs usually to composed bearing seat. Therefore, bearing can function more stably.

The advantages and uniqueness of JC series jaw crusher are as following:

1.Fast and easy adjustment of output granularity: Jaw PE, PEX jaw crusher adopt mechanic or hydraulic device to adjust discharge opening. Compared with shim, adjustment by double block is simpler, saver, faster, and reduces downtime.

2.Installation integrating motor & crusher: Integrative installation of motor chassis and crusher frame not only saves installation space of jaw crusher but also reduces the length of V belt. Thanks to synchronous movement of crusher frame, motor chassis and motor.Adjustable motor chassis can realize the adjustment of V-belt's tensile force to make the V-belt more durable.

3.Shock absorber installation: The crusher is fixed by the device of special rubber shock absorber, which absorbs effectively the its vibration at the peak point and meanwhile, allows crusher to displace in vertical and horizontal direction. In this way, the shock to foundation would be reduced.

Compared with traditional jaw crusher, JC series jaw crusher pays more attention on details in the process of design and manufacture. It uses high-strength materials, advanced manufacturing technology, which contributes to the stronger structure, higher reliability, larger crushing ratio, higher productivity, lower cost.
