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)
What is the production capacity of this plastic recycling machine?
The machine has a recycling capacity ranging from 80 to 300 kg per hour, depending on the material type, feeding speed, and configuration of the production line.
How does the 2-step extrusion system function?
The system features two extruders: Extruder 1 (140-150mm) and Extruder 2 (100-120mm). This multi-stage setup ensures thorough melting, homogenization, and consistent extrusion quality for complex or mixed plastic materials.
Can this machine handle light and fluffy plastic materials?
Yes, an optional forced feeder system is available specifically for light, fluffy materials like plastic films and fibers. This ensures stable feeding into the extruder inlet and prevents material bridging or idling.
Is it necessary to stop the machine to change the filter screen?
No, the machine is equipped with a polymer filter screen changer that features a dual hydraulic pump system. This allows for automatic, online screen replacement without the need to shut down the production line.
What electrical and control components are integrated into the system?
The machine incorporates high-quality components, including a Fuji Japan frequency inverter, a dual-motor system (75kw + 22kw), and an integrated electrical control cabinet containing a PLC, temperature controllers, and inverters for fully automated production control.
What cooling method does the system use?
It utilizes a water cooling method to cool the extruded plastic strips in a stainless steel water tank before they are cut into clean granules by the high-speed pelletizer.
