crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.
Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.

PE jaw crusher uses motor as its power. Through the motor's wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a regulated track. Therefore, the materials in the crushing cavity composed of fixed jaw plate, movable jaw plate and side-lee board can be crushed and discharged through the discharging opening
Jaw Crusher Features
1. simple structure, easy maintenance
2. stable performance
3. even final particles and high crushing ratio
Dehong jaw crusher series are based on years experience and technology development. The continuous improvement and refinement has made them the preferred jaw crusher for professionals and our customers.
They can meet most crushing requirements in primary and secondary crushing, and the largest compression resistance of the material is 320mpa. This series are widely used in stone mining, metallurgical, construction, smelting, hydraulic and chemical industries, etc.
The jaw crusher is the main equipment for coarse crushing (a section of crushing).
The main features are:
Simple structure, reliable performance, easy operation, easy maintenance, safe use, strong applicability, cheap price.
The jaw crusher is divided into two forms: compound pendulum and simple pendulum.
The main parts of a broken jaw are:
Frame, movable jaw, active eccentric shaft, supporting shaft (simply swinging), connecting rod, adjusting jack,
Model description:

Brief introduction
Jaw crusher is a kind of Stone crusher, and jaw crusher is also called Rock crusher. This series of Jaw crushers have many advantages which mainly used in breaking a variety of ore and the medium-size chunk of materials. The compression strength of the materials to be crushed is less than 320MPA. it can be divided into coarse crusher and fine crusher. We have all specification kinds of the products, and its feedstock size is 125mm-750mm. It is the first choice for Stone crusher plant; Primary jaw crusher is widely used in mining, metallurgy, building materials, roads, railways, water conservancy and chemical industries, etc.
Features and Advantages

2) Flexible capacity; Over loading protection;
3) Simple structure and easy to operate;
4) Easy replacement of wearing parts;
5) Long service life; High reliability;
6) Wide range of choices;Alternative ordinary and hydraulic types.
Jaw crushers / Jaw breakers operating environment
When in the process of the great broken stones broke into small stones, the first crusher is often referred to as �¢??master�¢?? crusher, the longest history and most solid crusher is jaw crusher. When feed to jaw crusher, materials from the top of the entrance into the broken room with tooth broken, the tooth broken tremendous force the material to the top of the wall, it will be broken into smaller stones. Supporting the tooth movement is an eccentric shaft. This axis runs through the fuselage frame. Eccentric movement is usually arisen by fixed at both ends of the flywheel axis. Flywheel and eccentric support bearing is often using spherical roller bearings. Bearing working environment is extremely harsh. Bearings must support enormous impact loadabrasive water and high temperature. Though the working environment is extremely harsh, the jaw crusher still can work very reliably. this is a key element to ensure the productivity.
Working principle
The main structure of the Jaw crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.
This Jaw crusher�¢??s crushing style is the type of driving extrusion. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When movable jaw is rising ,the included angle between the wrist plate and movable jaw become bigger to drive the movable plate to be close to the movable plate. At the same time the material is squeezed and rubbed, rolled to achieve multiple crushing; When movable jaw is descending, the included angle between the wrist plate and movable jaw becomes smaller. Now the crushed material is discharged from the crushing cavity, with the continuous rotation of the motor, the movable jaw crushing and discharging the material periodically to realize batch production.
