Impact crusher machine crushes materials with impact force. The materials were drop into the high-speed rotating of impeller and are crushed with the materials spread in the forms of umbrella – shaped around the impeller under the force of centrifugal. Then the crashed materials are thrown to the impact plates on the rotor for further crush and followed with a third crash back to the blow bar again, forming a closed-circuit loop. This process will not ends until the materials are satisfies the size required and discharged from the lower part of the machine. By adjusting the gap between the rotor support and impact rack, he size and shape of the finished powder can be varied. The degrees of power will be controlled by the screening equipment.

With the improvement of extractive and the increased block size of extractive material, single rotor impact crusher limites the increase of feeding particle size due to its own structure, thus double rotor had been created out. In order to increase the role of the second rotor, double rotor impact crusher with height difference came after. Going back to the energy-linear formula, we can see that the first rotor crushes the materials in a lower speed while the second one go with a higher speed, as a result, reduction ratio has improved.Scientific management, advanced processing technology and innovative manufacturing theory make Fote Heavy Machinery become the exporting base of jaw crusher machine, sand making production line and famous grinding equipment in China. What Hongxing has done is for the clients and we believe that quality is the best way to develop market.

Impact crusher crushing material excellence, high fineness requirement, which requires the sand out of the material is fine, the smaller is the system capacity. This aspect to the specific requirements, such as no singular requirements, overall of the fineness of the material can be set in the scheme for fine.The viscosity of the material: the greater the viscosity of the material, the more easy to adhere to. The viscosity of the material in the impact crusher cavity adhesion in sand walls, such as not clean up in time, will affect the work efficiency of impact crusher, serious when may also affect the normal work of the vertical crusher. Therefore, when selecting a material, it is important to note that the viscosity of the material not too big.
