How Does the Jaw Crusher Work

Jaw Crusher is a kind of Stone crusher, and jaw crusher is also called Rock crusher. This series of Jaw crushers have many advantages which mainly used in breaking a variety of ore and the medium-size chunk of materials. The jaw crusher can be used with the ore dressing equipment or used independently. Jaw crusher can be used to produce the aggregate for subgrade, railway ballast and construction sand and stone.
Jaw crusher working principle:
The motor drives the belt pulley and the belt pulley drives the eccentric shaft to rotate, and make the moving jar approach and leave the fixed jaw periodically, to crush, rub and grind the materials repeatedly, thus to make the material slower and slower and gradually fall down and finally discharge from the discharge opening.
The compression strength of the materials to be crushed is less than 320MPA. it can be divided into coarse crusher and fine crusher. We have all specification kinds of the products, and its feedstock size is 125mm-750mm. It is the first choice for Stone crusher plant; Primary jaw crusher is widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical industries, etc.
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.
This Jaw crusher’s crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing.
When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.
Jaw crusher main Features and Advantages
1) High efficiency and low operation cost;
2) Flexible capacity;
3) Simple structure and easy to operate;
4) Over loading protection;
5) Easy replacement of wearing parts;
6) Long service life;
7) High reliability;
8) Wide range of choices;
9) Alternative ordinary and hydraulic types.
Jaw crushers operating environment
When in the process of the great broken stones broke into small stones, the first crusher is often referred to as ‘master’ crusher, the longest history and most solid crusher is jaw crusher. When feed to jaw crusher, materials from the top of the entrance into the broken room with tooth broken, the tooth broken tremendous force the material to the top of the wall, it will be broken into smaller stones. Supporting the tooth movement is an eccentric shaft. This axis runs through the fuselage frame. Eccentric movement is usually arisen by fixed at both ends of the flywheel axis. Flywheel and eccentric support bearing is often using spherical roller bearings. Bearing working environment is extremely harsh. Bearings must support enormous impact load\abrasive water and high temperature. Though the working environment is extremely harsh, the jaw crusher still can work very reliably. this is a key element to ensure the productivity.

The price of jaw crusher in Kefid Machinery is reasonable.


At present, many broken equipment manufacturers have developed new type of crushers such as cone crusher, single-stage hammer crusher, high-efficiency tertiary impact crusher from time to time. But few manufacturers lay emphasis on the improvement of technology, except for the domestic high and new technology enterprise Kefid Machinery who is famous for the broken equipment and wear-resisting material production, have developed successively a new type of hypoid deep cavity mandibles crusher, superfine mandibles crusher, large-size jaw crusher. Super fine jaw crusher has changed the history of jaw crushers’ rough broken into the fine broken, which solve the problem of limestone tertiary impact crusher of the cement enterprise.
It is understood that, on one hand, as the international market competition is growing and upgrading, the pressure brought by foreign leading-edge technology and market share has greatly stimulated the urgent task of industry transformation and upgrade of domestic crusher. On the other hand, the state has formulated direct or indirect policies to promote the real economy and promote a good atmosphere of the equipment manufacturing industry innovation to build further policy system to support equipment manufacturing innovation, which is gradually guiding the transformation of the crusher industry development model. As a leader of mining machinery industry, Kefid Machinery is striving to occupy the international market by producing the mining equipment with innovation, such as cone crushers and the impact crusher.
The trends of steel industry may change the price structure of mine crusher equipment: With the soar of all kinds of steel price, the volume of sales in the market appears atrophy, the tendency of price is not clear, and constant high price of steel and iron ore which is expected to fall in public opinion is forming a contradiction. From late trend of steel price, the short term risk is not very big, but if the demand of downstream users cannot be effectively released, the possibility of a sustained rise in the price of steel is very small. Recently, export contract of steel is full, the main production are put in the export task and take control of the domestic market resources, which makes the inventory structure more reasonable. But after the many, if there is no sudden market events, export contract recently will be reduced because the fluctuations of RMB exchange rate cause the competitiveness of domestic steel resources export is inferior. The resources of the surplus are inevitably a test for the digestive ability of domestic steel market, recently, some steel mills and the big traders marketed quantity of their long-term contract and agreement in advance, in fact, this is a signal that market price of steel is viewed in differentiation, the view of the empty power gradually increase, so, it needs to be cautious and not be too optimistic of the late trend of the market. So, in a period of time of future, the price of the crusher also can rise because the influence of the steel price.
Under the double stimulation of external pressures and internal guidance, the innovation and development of domestic crusher industry will achieve new breakthroughs. For example, we can accelerate the improvement of the industry's internal structure, occupy the highlands of the international scientific and technological innovation, grasp the voice of the strategic emerging industries, and consciously use high-tech to improve the product performance, innovation and R & D to achieve new breakthroughs. The constant improvement and innovation of the production process will lead the innovative path of development of the crusher industry in China.
