La différence entre le déchiqueteur et le concasseur
Working principle of Plastic shredder
Shearing and tearing: The plastic is sheared and torn by the rotation of the double-axis or quad-axis blades, similar to “scissors cutting cloth”.
Low speed and high torque: Suitable for large pieces, thick walls or winding plastics (such as PET bottle bundles, plastic barrels).
Discharge form: Irregular flakes or strips (size 10-100mm), requiring secondary crushing.
Working principle of Plastic Crusher
Impact grinding: impact and cut plastics through high-speed rotating blades or hammers, similar to a “powder grinder”.
High speed and low torque: suitable for brittle plastics (such as PP, PS) or thin-walled materials (such as films, fibers).
Output form: uniform particles or powder (size 0.1-10mm), can be directly used for granulation or injection molding.
The difference between the applicable scope of plastic shredder and plastic crusher
The shredder focuses more on tearing and shearing, and is suitable for processing large or tough materials. Like waste tires, wood, plastic, paper, etc., the purpose is to tear the material into pieces for subsequent reprocessing or disposal.
The crusher is more about breaking plastic materials into small particles or powders through mechanical force.
Position in the plastic recycling line
Usually, in the process of plastic recycling and granulation, the plastic shredder is used before the plastic crusher. The plastic shredder first shreds the large waste plastic into small plastic pieces, and then the plastic crusher processes the plastic pieces into smaller plastic pieces. In order to enter the subsequent rinsing, drying and other processing links
