The impact crusher is a new generation of crushers, generally used as secondary crushing equipment, to achieve “more crushing and less grinding”. It adopts new manufacturing technology, special structural design, good grain shape, and various coarse, medium and fine materials (granite, limestone, concrete, etc.) whose compressive strength does not exceed 350MPa. It is widely used in various ore crushing, railway , highway, energy, cement, chemical, construction and other industries. The size of the discharge particle size can be adjusted, and the crushing specifications are diversified.
Feed particle size: ≤1300mm
Processing capacity: 30-800t/h
Applicable materials: limestone, coal gangue, granite, iron ore, feldspar, calcite, talc, etc.
Performance characteristics of impact crusher
- The feeding port is large, the crushing cavity is high, the material hardness is high, the lump is large, and the product stone powder is less.
- The gap between the impact plate and the plate hammer can be easily adjusted, effectively control the discharge particle size, and the particle shape is good.
- The impact crusher has a compact structure, strong machine rigidity, and a large moment of inertia of the rotor.
- High chrome plate hammer, impact resistance, wear resistance and high impact force.
- The impact crusher equipment has no key connection, convenient maintenance, economical and reliable.
- The crushing function is complete, the production efficiency is high, the mechanical wear is small, and the comprehensive benefit is high.
The working principle and structure of impact crusher
The impact crusher is a crushing machine that uses impact energy to crush materials. Driven by the motor, the rotor rotates at a high speed. When the material enters the action area of the plate hammer, it collides with the plate hammer on the rotor and breaks, and then is thrown to the plate hammer. It is crushed again on the counterattack device, and then bounces from the counterattack liner back to the action area of the blow hammer to be crushed again. This process is repeated. The material enters the first, second and third counterattack chambers from large to small for repeated crushing until the material is crushed to The required particle size is discharged from the discharge port. Adjusting the gap between the impact frame and the rotor can achieve the purpose of changing the material discharge particle size and material shape.
The structure of impact crusher is mainly composed of tie rod, front impact frame, rear impact frame, impact lining plate, main shaft, locking block, pressing plate, rotor frame, plate hammer, impact plate, rotor, etc.
