Impact Crusher

Short Description:

Impact crushers are utilized in aggregates production, mining operations, as well as in recycling applications. Depending on the type of an impact crusher, they are known for either high reduction ratios or capabilities to produce precisely shaped, cubical end products. Impact crushers can be used in all different stages of size reduction from primary crushing to the last step of the crushing process.

Impact crushers, or impactors as they are also called, are generally divided into two main technologies. The conventional type has horizontal shaft configuration, and for that reason it is known as a horizontal shaft impact crusher or shorter as HSI crusher. The other type has a centrifugal crusher with vertical shaft, and it is called a vertical shaft impact crusher or VSI crusher.

Working Principle of Impact Crusher

The impact crusher is a kind of crushing machine which uses impact energy to crush materials. When the machine works, driven by the motor, the rotor rotates at high speed. When the material enters the action zone of the plate hammer, it impacts and crushes with the plate hammer on the rotor, and then is thrown to the impact device to crush again. Then it bounces back to the plate hammer from the impact liner. The action zone is re-broken, and the process is repeated. The material is re-broken from large to small into the first, second and third counterattack chambers until the material is broken to the required size and discharged from the outlet. By adjusting the clearance between the counterattack frame and the rotor, the grain size and shape of the material can be changed.

Characteristics of Impact Crusher

1.Heavy-duty rotor design, as well as strict detection means, to ensure high-quality rotor. Rotor is the “heart” of crusher. It is also a part of impact crusher which has strict acceptance. It plays a vital role in the work.

2. Unique structural design, the finished product is cubic, tension-free and crack-free, with good grain shape. It can crush all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.) whose feed size is not more than 500 mm and compressive strength is not more than 350 MPa.

3. The impact crusher has the advantages of good particle shape, compact structure, strong rigidity of machine, large moment of inertia of rotor, high chromium plate hammer, high comprehensive benefits of impact resistance, wear resistance and crushing force.
