The plastic recycling granulating line is mainly used for recycling waste plastic barrels, plastic basins, plastic chairs, plastic toys, and other hard plastics. This plastic recycling pelletizing machine integrates crushing and cleaning, drying, granulating, and bagging, and is a professional piece of equipment for recycling waste plastics.
Meanwhile, Shuliy Machinery can place and install the PP PE flake recycling line according to the customer’s requirements.
Introduction of Plastic Recycling Granulating Line
The plastic recycling granulating line mainly consists of a plastic crusher machine, a plastic rinsing tank, a plastic pellet making machine, a cooling tank, and a plastic granule cutter. The PP PE flake recycling line realizes highly automatic production, which can turn hard plastics into recycled plastic pellets and save labor.
Shuliy Machinery has focused on plastic recycling granulating lines for more than ten years and has rich experience in manufacturing plastic recycling machinery. Very welcome to visit our factory.
Plastic Recycling Pelletizing Machine Process
Crushing – Cleaning – Drying – Melting – Extrusion Granulation – Pelletizing Cutting
- Firstly, the hard plastic materials, such as waste plastic basins, buckets, and toys, are broken down into pieces and flakes through a plastic shredder machine.
- Secondly, a plastic washing machine will clear the impurities such as dust and dirt.
- Thirdly, a horizontal dewatering machine is used for dehydrating and drying plastic chips after cleaning.
- Then, the flakes firstly enter into feeding conveyor and then they are melted with electromagnetic heating to transform pieces from a solid to a molten state.
- After that, the screw inside the plastic recycling granulator is used to apply pressure to the paste, pushing it through the head die to be extruded into strips.
- Lastly, the extruded plastic is rapidly cooled down and cured through a cooling device, such as a cooling water tank or an air-cooling system, and then cut into homogeneous pellets by a pelletizing device according to a preset size.

Application of Plastic Recycling Granulating Machine
Plastic recycling granulating line is a solution designed for recycling hard plastics such as plastic drums, plastic pots, plastic chairs, plastic pallets, fruit baskets, plastic containers, etc. Plastic recycling granulating line can turn hard plastics directly into recycled plastic pellets to achieve plastic recycling.

Working Principle of Plastic Recycling Granulating Line
The core principle of thermoplastic molding of plastic recycling granulating line is the reversible physical properties of heating and melting and cooling and solidification with the help of plastic materials. When the waste plastic enters the granulator, the heating system warms it up to above the melting point.
After that, it is transformed from solid state to viscous fluid melt, and then the screw rotates and pushes the pressure, so that the melt is uniformly plasticized and extruded through the die。
Finally, it is rapidly cured in the cooling system, and finally cut into pellets according to the specifications by the plastic strip cutting machine.
The whole process of the plastic recycling granulating line is only a physical phase transition without chemical structure destruction, thus realizing the recycling of waste plastics.
Main Machine of Plastic Waste Recycling Plant
Step 1: Plastic shredder machine
The plastic shredder machine can easily crush hard plastics into small-sized materials, thus reducing transportation costs and facilitating subsequent plastic pelletizing.
Step 2: Plastic washing machine
The plastic washing machine is used to rinse the crushed materials with the spiral device at the bottom to remove the sediment and other impurities and further ensure the cleanliness of plastic chips and improve the quality of recycled pellets.
Step 3: Horizontal dewatering machine
The horizontal dewatering machine is used to dry the cleaned materials. Because the moisture on the material will lead to bubbles in the melt and affect the quality of granulation, the waste must be dried before processing.
Step 4: Plastic pelletizing machine
The crushed and dried material is melted in the plastic pelletizing machine and extruded into long strips through the die head. The plastic pelletizer machine is the most important equipment in the plastic recycling pelletizing line.
Step 5: Plastic Strip Cutting Machine
The plastic strip cutting machine cuts long strips of cooled plastic into small, uniform pellets. Various machine models are available to meet different output requirements.
The exact configuration of the machine can be adapted to your needs. You are welcome to contact us for specific questions about the plastic recycling granulating line.

FAQ of plastic flake pelletizing line
What is the difference between PP and PE plastic?
First of all, the composition of the two is different; the main component of PP plastic is polypropylene, and PE plastic is the main component of PE plastic is polyethylene.
Secondly, the characteristics of PP and PE plastic are different. PP plastic strength, stiffness, and hardness heat resistance are better than PE and can be used at about 100 ℃. Has good dielectric properties and high-frequency insulation and is not affected by humidity, but at low temperatures becomes brittle, not wear-resistant, and easy to age. PE plastic extensibility, tear-resistance and impact resistance, high transparency, heat sealing, and processing performance.
What is the function of a horizontal dewatering machine?
Because if water is left on the surface of the plastic pieces, the water will be vaporized into bubbles by heat, resulting in the production of pellets with bubbles, voids and other defects, seriously affecting the quality of the pellets.
Can the plastic recycling granulating line produce granules of different sizes?
We can provide you with different models of machines according to your actual production needs, so that you can produce plastic pellets of the size you need.
