The improvement of the jaw crusher

PE/PEX Series Jaw Crusher has the features of high crushing and even product size ratio. It can be used to crush material, whose compression strength is not more than 320Mpa. This jaw crusher is mainly used in various industries, such as mining, smelting, road and railway construction, water conservation and chemical industry etc. PE Series is used in primary crushing, while PEX series is used in secondary crushing and fine crushing.

The improvement of the jaw crusher  ：
No 1.Change the nip angle from zero to negative, the material does not jam, but form a longer" equilibrium"with the linear movable jaw plate, the effective length is as long as 30-60mm, so that the discharge is parallel extrusion pressure for a period of time, which further make the material thinner and also aggrandize the discharge.

No 2. To ensure the extrusion times of the material in crushing cavity and to improve the crushing ratio, the technique properly increase the height of the crushing cavity to constitute the so-called "advanced type"crushing cavity, and to improve the yield, deduces new eccentric shaft speed formula, that is, the eccentric shaft speed of patent product can  reach 330-350rpm, which increases the number of the movable jaw to swing and strengthen the crushing function and also improve the machine output.

No 3. The wearing law of the compound pendulum jaw crusher jaw plate is that it is generally easy to wear in the discharge zone of fixed jaw plate, this technology make the fixed jaw plate into linear correction" -- Gauss curve".

No 4 curve advanced crushing cavity of Professor Dai Shaosheng. What's more, the pure pressure of crushing effect is five times of the shear stress, the material in the crushing cavity is repeatedly laminating crushed, which leads to the obvious improving of the crushing effect of jaw crusher, also promote a high crushing efficiency and discharge average particle size up to 5-10mm.
