impact crusher sale price in Ethiopia。The impact crusher can handle materials with a side length of 100-500 mm or less, with a compressive strength of up to 350 MPa, with a large crushing ratio, and the crushed materials are cubic particles. Widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries for medium and fine crushing materials. The size of the discharge particle size can be adjusted, and the crushing specifications are diversified.
Ethiopia The working principle of impact crusher
Impact crusher is a crushing machine that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at a high speed. When the material enters the action area of the blow hammer, it collides with the blow hammer on the rotor and breaks, and then is thrown to the counterattack device to be broken again, and then bounces off the counterattack liner. Return to the action area of the blow hammer for re-crushing. 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 and discharged from the discharge port. In order to facilitate understanding, the crushing equipment factory store uses a more intuitive dynamic diagram to demonstrate, as shown in the figure "Working Principle of Impact Crusher".
The stone material falls directly into the high-speed rotating turntable from the upper part of the machine; under the action of high-speed centrifugal force, it collides with another part of the flying stone around the turntable in an umbrella-shaped manner to produce high-speed collision and high-density crushing. A vortex movement is formed between the turntable and the casing, causing multiple blows and crushing.
Impact crushers structure in Ethiopia
Impact crushers include single rotor impact crushers and double rotor impact crushers. Among them, the single-rotor impact crusher has a relatively simple structure. The material blocks are fed from the feeding port. In order to prevent the material blocks from flying out during crushing, a chain curtain is installed in the feeding direction of the feeding port. The fed material blocks fall on the top of the grate screen, the small material blocks fall to the lower part of the casing through the grate slit, and the large material blocks slide along the screen surface to the rotor. A plate hammer with a certain height is fixed on the circumference of the rotor, and the rotor is rotated at a high speed by the motor through the V-belt belt. The material block falling on the rotor is impacted by the high-speed rotating plate hammer. After gaining kinetic energy, it hits the counterattack plate at a high speed, and then bounces back from the counterattack plate, and collides with the material thrown by the rotor in the crushing area. The space formed by the bar screen, the rotor, the impact plate and the chain curtain is called the first impact area; the space formed by the impact plate and the rotor is the second impact area. After the materials are crushed by mutual impact in the first impact zone, they then enter the second impact zone to be impacted and crushed again. The crushed materials are discharged through the discharge port at the lower part of the casing.
