PE Series Jaw Crusher Wiki

For a century, it has been renowned for its simplicity and reliability in the world of crushing and mining machinery industry.

PE series jaw crusher adopts the design principle of traditional compound pendulum jaw crusher. This principle has two advantages: simple structure, easy operation and maintenance; Stable performance, suitable for all kinds of hard brittle materials.

Since the end of 19th century, this machine has been widely used in the industries of ore crushing and construction processing. The core parts are made of super high manganese steel casting with longer service life and shorter downtime

In view of the bad working conditions of jaw crusher and the fast consumption of wear and tear parts, we choose the material of core parts in a very elegant way. According to the internationally advanced mode, we have adopted the high quality manganese steel castings that are more recognized at present. This casting greatly lengthens the service life of core parts and effectively avoids the excessive production operation time caused by downtime maintenance.

"Power off" insurance can effectively deal with overload and make production safer 

The bracket of PE jaw crusher is not only a force transfer component, but also an insurance part of the crusher. When the unbreakable materials fall into the machine and make the machine exceed the normal load, Shibang industrial design of the toggle plate can realize automatic fracture, let the crusher stop working, avoid the damage of the whole machine, and guarantee the production safety. 

Depending on the spirit of the craftsman, we will deal with it carefully and make it simple

Although the structure of the jaw fracture is relatively simple, it needs to be treated carefully everywhere in the process. For example, the perfect machining, heat treatment and inspection of inspection can ensure the strength and rigidity of the eccentric shaft. Precise feeding can ensure the weight and structure of the flywheel and groove wheel and enhance the balance of the crusher. In this regard, Shibang Industry has formulated strict quality inspection procedures, supplemented by advanced machine tool processing equipment, committed to making every jaw crusher nearly perfect.

Performance characteristics

1. The crushing chamber is deep and no dead zone, which improves the feeding capacity and output.

2. The crushing ratio is large and the grain size of the product is uniform.

3. The adjusting device of the gasket type discharge port is reliable and convenient, and the adjustment range is large, which increases the flexibility of the equipment.

4. The lubrication system is safe and reliable, with convenient components replacement and small maintenance workload.

5. The structure is simple, the work is reliable, the operation cost is low.

6. Equipment energy saving: single machine energy saving 15% ~ 30%.

7. The adjustment range of discharge port is large enough to meet the needs of different users.

8. Low noise and less dust.

Structural composition

PE series jaw crusher mainly consists of a frame, an eccentric shaft, a large belt pulley, a flywheel, a moving jaw, a side guard plate, a bracket plate, a back seat of the bracket plate, an adjusting screw rod, a reduction spring, a fixed jaw plate and a movable jaw plate, etc. Among them, the bracket also plays a role of insurance. In the process of breaking large stones into small ones, the first crusher is usually called the "main" crusher. When feeding the jaw crusher, the material is poured into the crushing chamber containing jaw teeth from the top entrance. The jaw teeth with great force pushed the material against the wall of the chamber, breaking it into smaller rocks. What supports the jaw movement is the eccentric axis. This shaft runs through the fuselage frame. Eccentric motion is usually generated by flywheels fixed at both ends of the shaft. Spherical roller bearings are often used for flywheels and eccentrically supported bearings, and the working environment of bearings is extremely harsh. Bearing must bear great impact load, abrasive sewage and high temperature. Although the working environment is extremely harsh, the jaw crusher still needs to work reliably, which is a key link to ensure the efficiency of production.

Working principle

The crushing method of PE series jaw crusher is curved extrusion type. The motor drives the belt and pulley, moves the moving jaw up and down through the eccentric axis. When the moving jaw rises, the Angle between the elbow plate and the moving jaw becomes larger, thus pushing the moving jaw plate closer to the fixed jaw plate. At the same time, the material is crushed, rubbed. When the jaw moves down, the Angle between the elbow plate and the jaw decreases, and the jaw plate leaves the jaw plate under the action of pull rod and spring. At this time, the broken material is discharged from the lower mouth of the crushing cavity. With the motor turning continuously, the motor crushes and discharges the material periodically, realizing the batch production.
