Jaw crusher introduction:
Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. Jaw Crusher is a kind of stone crusher, and it is also called rock crusher, jaw breaker, stone jaw crusher, single toggle jaw crusher and aggregate jaw crusher. This series of stone crusher plant can reach the crushing ratio of 4-6 and the shape of final product is even. The rock crushers are widely used in mining, building materials, chemical industry, and metallurgy and so on. It is suitable for primary and secondary crushing for all and rocks with compressive strength less than 320 MPa. In construction, road and railway building, construction and other industries are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc. As a professional jaw crusher supplier, Shanghai Xuanshi jaw breakers have been sold to 75 countries, the price and quality of jaw crushers is widely recognized, we always stick to be your satisfying partner.

Mobile Jaw Crusher Features and Benefits:

1. The cavity of mobile jaw crushers is deep and with no dead area, to promote feeding capacity and output.
2. The size of the reduction ratio is big and the production size is even.
3. Adjustment device of the spacer style discharge mouth is convenient and reliable. And primary jaw crusher's adjustment range is big, which improves the flexibility of equipment.
4. Lubrication system of jaw crusher is safe and reliable. Unit replacement is convenient. And the work of maintenance is small.
5. Its structure is simple and operation is reliable. The operation charge is low.
6. Energy conservation: single machine's energy conservation is and the machine system energy conservation is more than twice of the single machine.
7. The adjustment range of the outlet is big, so it can satisfy the requirement of different customers.
8. The noise of Shanghai Xuanshi jaw crusher is low and dust is little when primary crushers work.

Working Principle:

The main structure of the Jaw Crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.
Jaw crusher uses motor as its power. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. During this process, the material is crushed and ground, thus the crushing will be done. When the moving jaw is down, the angle between lining plate and moving jaw becomes small, the moving jaw plate will leave the fixed jaw plate on account of the effect of pulling bar and spring, and then the crushed material will be discharged from the lower opening of the crushing room. With the motor continuously rotating and the material periodically crushed and discharged by the crusher, the mass production can be realized.

Use of jaw crusher:
(1) Start feeding after checking that the machine works well.
(2) Evenly put the material into the machine, and avoid putting material from the side or feeding too much to avoid over feeding, sudden load change or being blocked.
(3) Stop feeding before stopping machine. Stop motor after all materials discharged.
(4) Stop the motor if there is any stagnancy due to the blocking up of material inside the machine.
(5) The other side can be used if one side of fixed jaw plate and movable jaw plate are worn.
(6) Check all fixed parts before starting to use and tighten the part if it is loosening.
