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 production capacity of this plastic recycling machine?
The machine provides an output capacity ranging from 80 to 300 kg/hour, depending on the material type, feeding form, and customized configuration.
Q
What types of plastic raw materials can this equipment process?
It is suitable for processing plastic fragments, regrind powders, films, fabric scraps, and fibers. A forced feeder is optionally available for lightweight and fluffy materials to prevent bridging.
Q
How does the two-stage extruder system improve granulation quality?
The two-step extrusion system (Extruder 1: 140-150mm and Extruder 2: 100-120mm with 75kW + 22kW motors) ensures dual filtration, thorough plastification, degassing, and stable homogenizing for uniform pellet output.
Q
Can the filter screen mesh be changed without stopping production?
Yes, the polymer filter utilizes a screen mesh filter equipped with double hydraulic pumps, allowing for hydraulic automatic control and continuous online screen replacement without machine downtime.
Q
What cooling and granulation method is utilized in this line?
The system employs a water-cooling strand method where extruded strands are cooled in a stainless steel water tank and precisely sized by a high-speed pelletizer.
Q
What are the electrical specifications and control system components?
The unit operates on 380V 50Hz power voltage, equipped with Fuji Japan frequency inverters and a centralized PLC electric control cabinet for full automation and precision parameter regulation.
