Famous Plastic and Rubber Recycling Machine Suppliers, Factory
Plastic recycling machine or plastic granulating machine is a kind of mechanical equipment that processes various forms of plastic raw materials (such as new polymer materials, recycled plastic or film materials, and scraps) through high-temperature heating, melting, extrusion, filtration, cooling, cutting and other procedures into granular products of uniform specifications and shapes. These particles (referred to as "plastic particles" or "recycled granules materials"
Plastic Recycling Machine / Granule Making Machine
As a complete set of plastic recycling machine, it mainly consists of the following major equipment and systems:
1. Recycling plastic raw material feeding system
Full stainless steel hopper: It is used for storing plastic raw materials to be processed (fragments, powders, films, etc.).
Forced feeder (optional): For light and fluffy materials (such as films and fibers), it ensures stable and easier feed into the main extruder inlet, preventing bridging and idling.
2. Extrusion system (2 steps extruders)
Barrel: A sturdy metal cylinder with a heating ring and a cooling fan inside for precise temperature control.
Screw: According to different function is divided into several sections (feeding area, compress the molten area, homogenizing measurement area), its design (such as length to diameter ratio, the spiral groove depth) directly decide the performance of the machine and the application of the material.
3. Heating and cooling device
The electric heating ring heats the barrel, and the fan or water cooling system is responsible for cooling, jointly ensuring that the plastic melts at the optimal temperature.
4. Filter screen changer
It is used to filter impurities in the melt to ensure the purity of the particles. Hydraulic automatic control and online filter screen replacement are available without the need to stop the machine.
5. Discharge die head
A plate-shaped device with a specific number of small holes, from which molten plastic is extruded to form strips.
6. Water-cooled strip granulation
The extruded plastic strips are cooled in a stainless steel water tank and then cut into granules by a pelletizer.
7. Pelletizer
Equipped with high-speed rotating blades, it cuts the cooled plastic strips or the melt directly extruded from the die head into pellets of the required length.
8. Electric control cabinet
Integrated PLC, temperature controller, inverter, etc., used for precise control of the whole production line temperature, screw speed, feeding speed, cutting parameters such as particle velocity, realizing automation production.
Frequently Asked Questions (FAQ)
Q:What is the output capacity of this plastic recycling machine?
The recycling capacity ranges from 80 to 300 kg per hour, depending on the material type, feeding density, and operational configuration.
Q:Can this machine process lightweight materials such as plastic films or fibers?
Yes, it can be equipped with an optional forced feeder specifically engineered for light, fluffy materials to ensure continuous, stable feeding into the extruder and prevent material bridging.
Q:How does the filter screen changer operate without stopping production?
The system utilizes a hydraulic automatic screen mesh filter equipped with dual hydraulic pumps, allowing operators to change the filter screen online seamlessly without shutting down the main line.
Q:What cooling method is used during the pelletizing process?
The machine uses a water-cooled strip granulation method. Extruded plastic strands are passed through a stainless steel water cooling tank before being precisely cut into uniform granules by the pelletizer.
Q:What electrical components are used in the control system?
The electrical control cabinet integrates an intuitive PLC system, precise temperature controllers, and a high-performance Fuji Japan frequency inverter for full automation and stability.
