Jaw crusher, also known as jaw breaker or jaw breakers, fulfills crushing by imitating the moving of animals' jaws. It has been widely used in many fields,such as mining, metallurgy, building materials, highway, railway, water conservancy, chemistry and so on. It can crush all kinds of materials with compressive strength of not more than 320 Mpa.

The aircraft through the use of the intergranular laminated design principles of the special crushing cavity and contrast to match the speed, replace the traditional single particle crushing principle, to achieve selective crushing of materials, crushing uniform particle size. Two-way over the iron to release the hydraulic cylinder that allows the iron to smooth through the crushing chamber, and in the iron and transient nausea car Hydraulic top, automatic nesting, and avoid the spring cone crusher downtime for maintenance operations. Crushing cavity using high-performance non-contact labyrinth seals to improve the reliability of the blocking dust, reduce the cycle of iron contamination and equipment wear, and body to bring a unique lubrication system, greatly improving the service life of equipment.

Our stone jaw crusher is based on years of product development. The continuous improvement and refinement has made them the preferred Primary jaw crusher among professionals. Series of our stone jaw crushers are divided into 11 models which can meet most capacity requirements in primary crushing and secondary crushing, with low power consumption and easy maintenance. Every feature of these primary crushers has been carefully designed to provide superior quality and performance. They are widely applied in areas of mining, metallurgy, construction, smelting, hydraulic and chemical industries, etc. Wherein, large and medium-size stone jaw crushers are our competitive products; especially in designing and producing large-sized jaw crusher, we have already ranked the first place in China jaw crusher and foreign jaw crusher.

Jaw crusher although the swing simple and complex swing two types, but their works are basically similar, but large differences in the trajectory of the moving jaw. Swing jaw crusher, movable jaw is hanging in the supporting axis, so when moving jaw for reciprocating movement, the movable jaw trajectory point are rounded, and the horizontal travel great, while the the bottom of the movable jaw (Pai mine mouth) is the largest. Ore to fall into the crushing chamber, the upper are large nugget, which often reach the broken ore to the amount of compression necessary, therefore, the upper part of the large pieces of ore, repeatedly crushed repeatedly to be broken. Crushing load are concentrated in the lower part of the crushing chamber, the entire jaw plate is not evenly, thereby reducing the production capacity of the crusher. Small vertical stroke of the crusher, grinding stripping the role of small row of ore slow.
