PE Jaw Crusher, including coarse crusher and fine crusher, is widely applied in the road building construction, in the future for the mines, with the characteristics of large ratio of reduction, uniform size, simple structure, reliable working, easy maintenance, and low operating cost. It has not more than 320Mpa of the compression strength and 125mm~1020mm of the feeding size, and is the preferred equipment for primary and secondary crushing. LeiMeng jaw crusher absorbs the advantages of the similar products at home and abroad, and is developed into the crushing equipment with high efficiency and energy saving. As the main products of sandstone series, all the models of jaw crushers take the lead on terms of design, production, and after-sales service. PE series jaw crusher is widely applied in the mines, smelting, building materials, highway, railway, water conservancy and chemicals etc.

Jaw crusher working principle:

The Jaw Crusher is composed of rack, supporting device, operating mechanism(fixed jaw plate, movable jaw plate), transmission mechanism(eccentric rod, thrust plate, fly wheels, eccentric shaft), safety device, adjusting device(Wedge block adjusting device and gaskets adjusting device) backseat, screw, returning springs etc, in which the toggle plate plays a role of safety.

Working principle: By using motor as its power, the eccentric shaft is driven by the belt and belt wheel to make the movable jaw move up and down. When the movable jar ascends, the angle between the toggle plate and it becomes larger, push it toward the fixed jaw plate, reaching the purpose of crushing the materials. When the movable jaw descends, the angle becomes smaller, in the action of draw bar and spring, depart from the fixed jaw plate and discharge the materials, when the pressure rises to the strength beyond which the materials can bear, the crushing happens. Otherwise, when the fixed jaw swings in the opposite direction departing from the fixed jaw, the materials move downward by the self weight. Every periodical movement of the movable jaw will make the crushing effect on the materials, and send them a distance downward. The crushed materials will be discharged through the discharging opening after several periods.

Jaw crusher operating cycle:

In the process of large stones crushing into the small ones, the first step of crusher is called primary crusher. The jaw crusher is of the most common use and hardest one. The materials are fed into the crushing cavity from the top, forced to the cavity wall by the jaw tooth driven by the eccentric shaft throughout the frame, and crushed into smaller stones. The eccentric movement is normally made by the fly wheels fixed on the both ends of the shaft. The roller bearings in support of the flywheels and eccentricity must bear the large impact load, Abrasive sewage, and high temperature. In spite of that, the jaw crusher can work reliably, which is the key link for guaranteeing the production efficiency.

Jaw crusher features:

1. Deep crushing cavity without dead zone, improve the feeding capacity and output.

2. Big ratio of reduction, even product size, low noise, and small dust.

3. The gaskets adjusting device of discharging opening, reliable and convenient, with large adjusting range, increases the flexibility of the equipment.

4. Safe and reliable lubricating system, easy to change the parts, small maintenance workload.

5. Simple structure, reliable operation, low operating lost.

6. energy saving 15%~30% for one machine, more than doubled for the system

7. Large adjustable scope of discharge opening can meet the requirements of different customers.
