Centrifugal machine Technical Field The invention belongs to the field of centrifugal devices, and particularly relates to a centrifugal machine. Background The traditional centrifuge consists of a rotor and a screen, the material is beaten through the high-speed rotation of the rotor, so that the material generates centrifugal force, moisture is separated due to the separation of the screen, the material stays in a cavity, and the dehydrated material is pushed to enter the next process through a spiral blade on the rotor. However, the conventional centrifugal machine needs a large centrifugal force for dehydration, so that the rotor needs a high rotating speed, and the rotor is strongly flapped to the materials in the high-speed rotating process to cause serious material damage. Taking dehydration of bottle flakes and box-supporting flakes as an example, the loss rate of the bottle flakes in the process is more than 5%. The material of the box supporting sheet is more brittle, the loss rate is more than 10%, and the material recovery is very difficult. In addition, because the damaged powder that produces of material is a large amount, very easily causes the jam to the screen cloth, causes the dehydration rate to descend, and need to stop the clearance to the screen cloth regularly lead to wasting time and energy, cause the influence to enterprise continuous production.
