Impact Crusher Overview

Imapct crushers are suitable for materials whose compressive strength is under 360Mpa, and particle size is under 500mm. This kind of machine features easy maintenance, high crushing ratio and crushing efficiency etc. With end products in cubic shape, impact crushers are the ideal crusher for aggregates processing in high-type highway building, water conservancy and power construction.
    Compare to hammer crusher,impact crusher has bigger reduction ratio and Can fully use the high speed impact energy of entire rotor . But because the impact crusher board hammer is extremely easy to wear, it also is restricted in the hard material stave application.impact crusher is usually used to break thick garrulous, garrulous or the limestone, the coal, the calcium carbide, the quartz, the dolomite, the curing iron ore, the gypsum and the industrial chemicals which are hard following brittle material.
    It is the ideal machining equipment for aggregate for high-class highway pavement and construction of hydropower facilities. With excellent capacity and performance, the impact crusher is widely used in machining of reduced stone for highway construction, hydraulic engineering and architecture, etc.

Impact Crusher Application

Imapct crushers are suitable for materials whose compressive strength is under 360Mpa and side length is under 500mm. They are preferred to crush granite, limestone, rivel gravel, etc.

Impact Crusher Main Features and Benefits

1. Energy-efficient.
    2. Unique structure, keyless connection.
    3. Blow bar made of high chromium steel, impact plate with a special shape.
    4. End products with cubical shape.
    5. Easy operation and maintenance and high reliability.
Impact Crusher Working Principle
Impact crushers use impact energy to crush materials. Driven by the motor, the rotor revolves at a high speed. Revolving blow bars in the rotor blow the materials. Then the materials will be thrown to the impact plates for secondary crushing. The materials will be shot back to the blow bars again . This process repeats until the materials are crushed to the required size and discharged through the discharging opening at the bottom of the machine. Adjustinng the gap between the impact rack and rotor support, the size and shape of the end products can be changed.
    The impact crusher uses plate hammer on the rapidly rotating rotor to generate high-speed impact to crush the materials in the crushing cavity, and casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity. The materials are crushed again, and then, they return to the plate hammer to undergo the process above repeatedly.
    The materials are bumping with each other when being sent between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged.
