The jaw crusher is one of our product groups capable to crush easily even the hardest material and the hydraulic system enables the easily and rapidly adjustment of the jaw capacity in accordance withy the product volume, if you wish to lift a material from the machine.

It is also possible to use the high capacity primary impact crusher from our products range for primary and secondary applications. Thanks to the exchangeability of the wearing parts, the extension of machine’s utilization life and handling-convenience is ensured. Further, through the hydraulically open-able case also an ease and rapid maintenance facility is ensured. This product group designed in order to supply you a facile services, is suitable for lifting materials of any hardness.

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.

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 1) High efficiency and low operation cost; 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.

The jaw crusher is of curved extrusion type. When working, the motor drives the belt and pulley to move the movable jaw up and down through the eccentric shaft. When the movable jaw rises, the angle between the elbow plate and the movable jaw becomes larger, so as to push the movable jaw plate to approach the fixed jaw plate. The material can be multi broken through the extrusion, rubbing and grinding between the two jaw plates. When the movable jaw goes down, the angle between the elbow plate and the movable jaw becomes smaller, and the movable jaw plate is under the action of the pull rod and spring. After leaving the fixed jaw plate, the crushed materials are unloaded freely through the discharge port at the lower part of the jaw cavity under the action of gravity. With the continuous rotation of the motor, the moving jaw performs periodic crushing and discharging to achieve mass production.
