      Product description

      Impact Crusher:
      The history of the impact crusher dates back to the 1950s, and it has been a long time since the birth of the world's Taiwanese jaw crusher. With the development of productivity, the jaw crusher can not fully meet the needs of the crushing technology, so on the basis of the jaw crusher, people have designed the impact crusher.
      The impact crusher can process materials with a side length of 100-500 mm, a compressive strength of up to 350 MPa, a crushing ratio, and a cubic particle after crushing. Widely used in building materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical and other industries for medium and fine materials. The size of the discharge material can be adjusted, and the crushing specifications are diversified.


      Working principle of impact crusher


      The impact crusher is a crushing machine that uses impact energy to break up materials. When the machine is working, the rotor rotates at a high speed under the driving of the motor. When the material enters the action area of ??the hammer, it collides with the hammer on the rotor, and then is thrown to the counter-attack device to break again, and then rebounds from the counter-attack. Returning to the hammer action zone, the process is repeated, and the process is repeated. The material is repeatedly broken into the first, second and third counter-attack chambers until the material is crushed to the required particle size and discharged from the discharge port. Adjusting the gap between the counter-rack and the rotor can achieve the purpose of changing the material discharge size and material shape. The stone material falls directly from the upper part of the machine into the high-speed rotating turntable; under the action of high-speed centrifugal force, the flying stone that is shunted around the turntable in another part of the turntable produces high-speed collision and high-density crushing. After the stone hits each other, it will A vortex motion is formed between the turntable and the casing to cause multiple blows, friction, and pulverization, and is discharged straight from the lower portion. A closed loop is formed multiple times, controlled by a screening device to achieve the desired particle size.


      Impact crusher performance characteristics:


      1. The back plate of the rotor can withstand the high moment of inertia of the rotor and the impact crushing force of the hammer;
      2. Optimized design into low-speed, multi-crush cavity impact crusher, its line speed is reduced by 20%-25% compared with the general counter-attack, and high production capacity is achieved with low energy consumption;
      3. It has the functions of three-stage crushing and shaping, so the crushing ratio is large, the shape of the product is cubic, and it can be selectively broken.
      4, reasonable hammer structure, with the advantages of fast loading and unloading, multiple transposition, etc., can greatly shorten the time of changing the hammer;
      5. With the new manufacturing technology, a high wear resistance and high toughness chromium, molybdenum and vanadium alloy materials have been successfully developed to solve the problem of fracture of hard materials. Greatly improve the service life of the hammer;
      6, unique counter-toothed plate, no key connection, easy maintenance, economical and reliable;
      7. Counter-attack is equipped with multi-functional hydraulic station, with hydraulic high-speed discharge gap, counter-attack plate stable vibration reduction and automatic opening of the body.
