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: 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 functions, it 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 decides 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
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
Q
What types of plastic materials can this recycling machine process?A
This plastic recycling machine is designed to handle a wide range of plastic materials, including fragments, powders, films, fibers, and other light or fluffy plastics. The optional forced feeder further expands compatibility with difficult-to-feed materials.Q
What is the recycling capacity of this granule making machine?A
The machine offers a recycling capacity of 80 to 300 kg per hour, making it suitable for both small-scale and large-scale plastic recycling production lines.Q
Does the machine support continuous operation without stopping to change the filter screen?A
Yes. The machine is equipped with a hydraulic automatic screen changer that allows online filter screen replacement without halting production, significantly improving operational efficiency and reducing downtime.Q
What power supply and voltage does this machine require?A
The machine operates on a standard 380V, 50Hz power supply. The main motor is rated at 75kW, and the secondary extruder motor is rated at 22kW. A Fuji Japan frequency inverter is used for precise speed control.Q
How does the cooling system work in this plastic recycling machine?A
The machine uses a water cooling method. After the molten plastic is extruded into strips through the die head, the strips are cooled in a stainless steel water tank before being cut into granules by the pelletizer, ensuring consistent pellet quality.Q
Is the production line automated and easy to control?A
Yes. The machine features an integrated electric control cabinet with PLC, temperature controllers, and inverters. This enables precise automated control over temperature, screw speed, feeding speed, and pellet cutting parameters throughout the entire production line.
