Single Cylinder Hydraulic Structure of Impact Crusher
The impact crusher has the characteristics of large crushing ratio, high efficiency, low power consumption and uniform particle size. The impact breaker is suitable for crushing hard materials, so it is still widely used in the world. The experts of Henan Hongxing Mining Machinery have transformed the impact crusher with the hydraulic device to make the impact crusher become more complete.
The impact crusher has a swinging angle which is 4 times larger than the swinging angle of the jaw crusher. In addition, the impact crusher has the rotating speed which is 2.5 times higher than the rotating speed of the jaw crusher. In such high-speed and large-stroke crushing process, the materials suffer from large-stroke impact unlike the slow-speed and small-stroke impact in the jaw crusher. This kind of impact crushing method is conducive to crushing the material. Therefore, the crushing efficiency is high. Due to the high speed and large stroke of the impact crusher, 95% materials in the crushing cavity are in the decline state of motion along the cone. It is means that only 5% materials are in the crushing state at any moment. Since 95% materials are in the decline state, the passing capacity in the crushing cavity is large and the output will be greatly improved. Since only 5% materials are in the crushing state, there is only 5% area in the whole crushing cavity us used for crushing materials. As a result, the energy consumption is low. Further, in a partial area of the crushing chamber, very high pressure will be produced for the materials per unit area, which makes the impact crusher is suitable for crushing hard ore.
The parallel zones with different lengths are set in the lower part of the crushing capacity and the rotating speed is high, which can ensure that the materials can be crushed once at least in the parallel zone. Therefore, the particle size of the materials crushed by the impact crusher is uniform. The impact crusher can be used for medium crushing and fine crushing. The difference between the medium crushing and the fine crushing lies in the difference of the shape and the size of the crushing cavity. The other structural principles are exactly the same.
