The impact jaw crusher is mainly used for the crushing the medium-hard and hard materials. Its main features are the followings. The crushing chamber is a tilt space with different tilt angles, which can form two crushing cavity, namely the coarse crushing cavity and the fine crushing cavity. The butterfly spring is used to achieve the overload protection. The operation speed is high. The impact jaw crusher is composed of the moving jaw liner, fixed jaw liner, moving jaw, spindle, eccentric shaft, bearings of the roller, rod head, connecting rod, adjusting screw, insurance spring, adjustment wedge, beams, support plate, support head, flywheel and the rack.

Compared with other crusher machines, the impact jaw crusher has the advantages of low production cost and high working efficiency. The impact jaw crusher is generally made of the highly wear resistant manganese steel liner, because the liner of the jaw crusher has very high wear requirements. When the jaw crusher works, there are two jaw plates in the crushing cavity. One jaw plate is fixed which is called the fixed jaw. The upper end slightly tilts to the outside and it is fixed on the front cavity wall of the crusher. The other jaw plate moves back and forth which is called the moving jaw or the jaw tongue. The position of the moving jaw is tilt. The moving jaw forms a trapezoid crushing cavity with the fixed jaw. Since the working area formed by the moving jaw and the fixed jaw mainly contacts with the materials to be crushed, they have very high wearable requirements. 

The development of the mineral resources is inseparable from the mining machinery and equipment. Therefore, as the important mining machinery equipment, the impact jaw crusher is indispensable. As the first production process of the mineral crushing production line, the impact jaw crusher can be used for the primary and simple crushing operation for the stone material crushed from the mine so that the stone material is easier and better to be handled into the next program. 

There are many types of the jaw crusher at home and abroad. The jaw crusher products produced by various manufacturers are different. As a leader in Mining Machinery industry, Henan Hongxing Mining Machinery will provide you with the most professional service and products.
