It is a special equipment for shredding waste paper and waste cartons. The carton double-shaft shredder is specially designed for shredding various paper materials. It is suitable for the refinement of various waste paper materials. It has the advantages of uniform output and controllable size. The working principle of the carton double-shaft shredder is Similar to the double-shaft shredder, it uses two sets of rotors with shredder blades to rotate relatively in the machine cavity, so that the material entering the machine cavity is squeezed by the principle of shrinking the angle between the two shafts. After the design enters the angle between the two axes, the material is fixed by the edge of the blade to further create conditions for the shrinkage of the angle. After the material is stressed and reaches the yield strength of the material, the material begins to break between the blades, thereby completing the shredding effect.
