The Industrial Plastic Granulator or Shredders are the equipment for re-grinding and recycling waste plastics or plastic auxiliary equipment for injection molding, blow molding or extrusion. They are used for crushing and recycling plastic materials such as PU, PVC, PC, ABC or pipes, plates, and packaging materials. There are many designs of industrial plastic granulators and shredders for size reduction, granulation, recycling devices and accessories. Whatever your required capacities are, take 5 minutes to read this article and you will have a complete understanding.


What is Industrial Plastic Granulator Machine?

It is the equipment used for crushing all kinds of plastics and rubbers, such as plastic profiles, pipes, rods, silk threads, films, waste rubbers, and plastic products.

How does it work?

The motor drives the blade rest shaft to make the rotating blade on the shaft rotate relatively against the machine's fixed blade, with the best cutting angle. Staggered rotating blades on the rest enable materials to drop inside under the squeezing, tearing and cutting action, thus crushing the materials.


Types of Industrial Plastic Granulator Machines

  • Low-speed Granulator: Applied to crush plastic sprues and a few rejects for reuse instantly.

  • Central Granulator: Suitable for centralized crushing of all kinds of materials, such as wastes or rejected parts from injection molding, blow molding, or extrusion lines.

  • Roll-feed Granulator: Applicable to granulating and recycling plastic films. After being pressed toughly by a material scroll, films are sent to a cutting chamber to be cut into granules to reuse.

  • Shredder: Applied to shred extremely thick, rigid, solid plastics, rubber, and wood, including large wastes produced by injection molding, blow molding, or extrusion molding.


Key Components of Plastic Granulators

  • Teeth blade: Used for instant recycling of thick and long or tough sprues and crushing a few rejects finely.
  • Paddle blade: Used for cutting thin-walled shells and tubes, bottles, flakes, pipe materials, profiles, etc. It allows increased efficiency and reduced energy consumption. It is suitable for cutting thin flakes and parts inside the cutting chamber.
  • Staggered blade: Staggered rotating blade design can decentralize the working load when granulating to increase cutting efficiency, making it easy to grab the materials to be crushed. The staggered blade is suitable for processing hard shells and solid materials.
