PE Series Jaw Crusher

PE Series Jaw Crusher is commonly known as jaw crusher, and is usually used in the production lines of various stones and ore crushing as primary crusher. This product simulates the movement of animal’s two jaws, extruding, twisting and grinding the materials in the crushing cavity through the opening and closing of two jaw plates (moving jaw and fixed jaw).

PE Series Jaw Crusher Basic Introduction

Over the past one century, it has been renowned in the world of mining machine by simpleness and reliability

PE series jaw crusher adopts the design principle of traditional compound pendulum jaw crusher, which has two advantages: simple machine structure, easy for operation and maintenance; stable performance, suitable for materials of various brittlenesses. Since the end of 19th century, this machine has been widely used in ore crushing, building aggregates processing and other related industries.

Core parts use superstrong high manganese steel casting, longer service life and shorter downtime

Allowing for the operating conditions of jaw crusher are relatively severe and the quick-wear parts will be consumed rapidly, we thought deeply in selecting the materials for core parts, and adopted high-quality high manganese steel casting which is most recognized in the world at present. This casting greatly extends the service life of core parts and effectively avoids too many shutdown and maintenance tasks occupying the production operation time.

"Power failure" safety device effectively responds to overload and makes the production safer

The elbow plate of PE series jaw crusher is not only the force transmitting component, but also the safety part of the crusher: when materials which cannot be crushed fall into the crusher, making the load of machine exceed the normal level, the elbow plate designed by SBM can realize automatic fracturing and then stop the crusher, thus avoiding the damage of the entire machine and guaranteeing the production safety.

Relying on craftsman spirits, we execute precise processing, make simple out of common

Even though the structure of jaw crusher is relatively simple, all processing procedures require precise processing, for example: only perfect machining, heat treatment and flaw inspection can guarantee the eccentric shaft to possess sufficient strength and rigidity; only precise blanking can guarantee the weights and structures of flywheel and grooved wheel to enhance the operating balance of crusher…For this purpose, SBM formulates strict quality inspection procedures and uses advanced machine tool machining equipments to deliver perfect jaw crusher products.

Jaw Crusher Working Principle

When the jaw crusher work, the movable jaw plate for the fixed jaw for periodic reciprocating motion, sometimes close, sometimes away. When approaching, the material is squeezed between the two jaws, splitting, shock and broken; when left, has been broken material by gravity and discharged from the discharge port.

In the process of breaking the huge stones into small stones, the first crusher is usually the "main" crusher. The longest and most rugged crusher is the jaw crusher. When feeding the jaw crusher, the material is poured into the crushing chamber containing the jaw teeth from the top entrance, and the jaw teeth pierced the material to the chamber wall with great power and broken it into smaller stones. Support the jaw movement is an eccentric shaft, this eccentric shaft through the body frame. Eccentric motion is usually caused by a flywheel fixed at both ends of the shaft. Flywheel and eccentric support bearings are often spherical roller bearings, bearings must withstand a huge impact load, abrasive sewage and high temperature.
