The impact crusher are ideal for secondary crushing. impact crusher is a new stone crusher machine that absorbs advanced technologies at home and abroad. Dealing with the material with the side length 500mm, not more than 320Mpa anti-pressure strength, impact crusher can be widely used in the first and secondary crushing process. The impact crusher is characterized by great reduction ratio, high reduction efficiency, convenient maintenance, etc. Impact crusher is widely used in crushing plant for highway construction, hydraulic engineering and architecture, mining industry etc for crushing quartz, basalt, shaly, kaolin, limestone, marble etc.

The structure of Impact crusher
Impact crusher’s main parts: spring, railings, retaliate after rack, rack, retaliate plate, square steel, plate bolt, flip device, spindle, plate hammer, rotor frame, plate, locking block, clamping piece and so on.

Working principle of impact crusher
This impact crusher machine crushes materials with impact force. When the materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the materials will be shot back to the blow bar again for the third crush. This process repeats until the materials are crushed to the required size and discharged from the lower part of the machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support.

Features and benefits of impact crusher
1.Cubic shaped end products
2.Adjustable end products sizes, simple crushing process
3.High chrome and abrasion resistant blow bar, powerful impacting force
4.Non-key connected connected, easy maintenance, economical reliable
5.Compact construction, high efficiency

Application
Crusher is widely used for a wider range of material hardness, so in many cases we can see the work of crusher scene. Dry Process Cement limestone with a single paragraph to the impact crusher can move material along the joints to produce the level of fragmentation, the material was uniform cube shape.
After the bulk material into the crushing chamber between the back plate and the rotor, the rotation of the rotor portion obtained by the kinetic energy between the back plate and rotor repeated shocks, after the first stage back cavity, the cavity back and bottom of the second stage were grinding gradual crushing cavity, to achieve the required particle size.
