Impact Crusher Working Principle
Impact Crusher Mahine is the use of impact energy to break the material broken machinery. The machine work, driven by the motor, the rotor high-speed rotation, the material into the zone plate hammer, hammer and hit the rotor on the board broken, and then was thrown back again on the broken device, and from then on the back liner bounced back to hammer the role of district re-broken, this process is repeated, the material descending into one, two, three broken back cavity repeated until the material is broken to the desired size, from the discharge port. Adjust frame and back up the gap between the rotor material change in the shape of particle size and material purposes. Stone from the machine directly into the upper high-speed rotation of the turntable; under the effect of centrifugal force at high speed, with another way to divert part of the umbrella to fly around the wheel high-speed collision with the stone produces high-density crushed stone in the fight against each other, then they will formed between the turntable and the chassis number of the vortex motion caused by each blow, rubbing, grinding, through discharge from the bottom. Form a closed loop several times, controlled by the screening equipment to the required size.
In 1924, the Germans developed the first single, two models of dual-rotor impact crusher, crushing machine when the structure is similar to a modern squirrel cage crusher, because in terms of structure, or from the works on the analysis of It is with crusher features. As the material requires repeated impact, the process can be broken free and unobstructed discharge, but due to the material strength and crusher of capacity constraints, the model gradually converted to cage-type crusher, used in hard look at the crushing.Stone crusher machine.
To 1942, the Germans Andreson at the conclusion of cage-type crusher hammer crusher working principle of the structural characteristics and on the basis of invented and modern crusher structure similar to the AP series impact crusher. Benefit from this crusher production more efficient, can handle more to the material, and its structure is relatively simple in form, easy to move, so, this crusher has been developed rapidly. With the crushing and screening and crushing theory of increasingly sophisticated technology, further development of various high-performance crusher is also emerging, foreign production crusher manufacturers are more well known that the United States Cedar ids, Inc. (formerly Iowa Machinery company), Sweden Svedala, Finland Nordbe pen company in France and Spain Rover Dragon, Germany Hazemag, KHD, heart upp company, Kawasaki Heavy Industries, and so on.
Meanwhile, in order to enhance the mobility of crusher has also developed a tire-and track-type mobile crushing stations, wheel-type crusher is popular in America, tracked more popular in Europe. In fact, Impact Crusher in China relatively late, to the 1950s, China really has a crusher, so that our crushing and screening equipment, Crusher Machine. mostly 50's came out. In the 1980s, we made crusher limited to dealing in coal and limestone and the like hard material.
