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
Q What types of plastic materials can this recycling machine process?
This plastic recycling machine is designed to handle a wide variety of plastic materials, including fragments, powders, films, fibers, and other forms of waste plastics such as PE, PP, PET, and similar polymers. The optional forced feeder makes it especially effective for light and fluffy materials like films and fibers.
Q What is the production capacity of this granule making machine?
The recycling capacity of this machine ranges from 80 to 300 kg/hour, making it suitable for small to medium-scale industrial production. The actual output depends on the type and condition of the input plastic materials.
Q Does the filter screen need to be changed manually, and will it stop production?
No. This machine is equipped with a hydraulic automatic filter screen changer that allows online replacement without stopping the machine. This ensures continuous production and minimizes downtime, significantly improving overall efficiency.
Q What power supply and voltage are required for this machine?
The machine operates on a standard power voltage of 380V at 50Hz. The motor configuration includes 75kw and 22kw units for each extruder, and the frequency inverter is sourced from Fuji Japan for reliable performance and energy efficiency.
Q How is the temperature controlled during the extrusion process?
Temperature is precisely managed through an electricity-based heating system using electric heating rings on the barrel. Cooling is handled by a water cooling method or fan system. The integrated PLC electric control cabinet monitors and adjusts all parameters automatically to ensure optimal melting conditions.
Q What is the advantage of using a 2-step extruder system?
The 2-step extruder design (Extruder 1: 140-150mm, Extruder 2: 100-120mm) allows for better degassing, more thorough melting, and improved homogeneity of the plastic melt. This results in higher-quality granules with fewer impurities, and it is particularly beneficial when processing contaminated or mixed plastic waste materials.
