Jaw Crusher is used to reduce the large material to small piece. Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material to be crushed is 320MPa. The jaw crusher is widely used in mining, metal industry, building material, highway, railway, and chemical industry. The main rack structure of jaw crusher are the eccentric shaft, the pulley, flywheel, moving jaw, side rack, plate elbow, Wrist plate back seat, screw-gap, adjusting the crack screw rod, resetting spring, fixed board plate and moveable board etc. Wrist plate has also played an important role of insurance.
This series of jaw crushers crushing way is the tune moves the extrusion. The engine 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 between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves away from fixed jaw by the pulling of Rod and spring, the products such as stone after crushing will be discharged from the outlet. This crusher for a simple, reliable and hard materials can be broken and the advantages of being widely used in mineral processing, building materials, ceramics, and other silicate and industrial sectors. Jaw crusher adopts to discontinuous crushing principle, so the productivity is lower for its impact vibration, energy consumption is higher, and coexistence of the products is not as regular as that of the gyratory crusher.
But it possesses the merits of small height of the machine, simple structure, reliable working, easy manufacturing and easy maintenance. No matter what type of crusher is, according to the comparison between the practical requiring the parameter and the basic parameter of the crushers instructions, first the demand of feeding coexistence, discharging coexistence as well as the productivity should be satisfied. Advantages of jaw crusher: 1. The crushing chamber is deep and smooth, enhancing the feeding capacity and production. 2 High crushing ratio, homogeneous end product. 3 Adjusting the discharge opening through gasket, the adjusting range is wide to meet the customer’s different requirement. 4 Safety and reliable Lubricate system, easy maintenance and replacement. 5 Single machine can save energy to 15-30%, a set of machine can save energy doubly. 6. Low noise and little dust. Stone production line:
