The plastic pellets making machine is a device that used to recycle and process waste plastics and make recycled plastic pellets. It is suitable for recycling common waste plastic products such as polyethylene (plastic film, beverage bottles, plastic bags, etc.) or polypropylene (waste woven bags, packing bags, tied ropes, etc.). Recycled plastic pellets can be produced through major steps such as extrusion, cooling, and pelletizing. The processed plastic pellets have a wide range of uses and can produce higher benefits.

The recycled pellets raw materials are mainly plastic waste, agricultural greenhouse film, convenient bag, cement bag, food packaging bag, woven bag, beverage bottle, plastic basin, plastic bucket, toy, sandal, vehicle bumper, household appliance shell, etc. They are all high-quality raw materials for recycled pellets. With raw materials, how to make recycled plastic pellets?
How to make recycled plastic pellets? A ZLSLG300B plastic pellets making machine is indispensable.
Type Power (kw) Output (kg/h) Weight (kg) Package size (mm) ZLSLG300B 22 600-800 305/325 *560*Before granulation, a crusher is needed to crush the plastic waste into 2-3mm size to make it meet the requirements of entering the plastic pellets making machine. If you need to process more raw materials, but also need to be equipped with a feeder.
Since the raw material comes from discarded plastic products, it is inevitable that there will be residual pollutants, so the raw material needs to be cleaned before making recycled plastic pellets.
Clean plastic raw materials need to be crushed by crusher to meet the processing standard of plastic pellets making machine.
The waste plastic is crushed by a crusher and sent to the feeder by an automatic hoist and then feeder feeds the material into the plastic pellets making machine. After entering the plastic pellet mill, the material is mixed and re-plasticized under the action of compression and external heating of the screw. With the increasing of temperature and pressure, it presents a viscous flow state and is pushed to the head part by certain pressure. Finally, the plasticizer is cut into pellets by a cutter.
As the temperature of the formed recycled plastic pellets by the plastic pellets making machine is still very high, it needs to be cooled through the cooling system. After cooling to normal temperature, it can be packaged with the packaging machine.
The above is the press of how to make recycled plastic pellets. Waste plastics can be made into recycled plastic pellets through plastic pellets making machine, which can not only reduce the pollution of plastic waste to the environment, but also create huge economic benefits. So it's a very worthwhile business to invest in.
As plastic manufacturing companies continue to expand, so does the production of plastic waste. However, repurposing plastic waste is possible through the plastic pelletizing recycling system. This system converts plastic scraps into usable clean raw material in a closed-loop recycling process.
What is Plastic Pelletizing?
Plastic pelletizing is the process of converting scrap plastic into pelletized plastics. The process involves cutting plastic scraps into small pieces and heating them until they melt. The molten plastic is then passed through a die, which produces cylindrical pellets. These pellets can be reused as raw material in manufacturing plants, thereby reducing raw material costs.
Types of Pelletizers
There are different types of pelletizers, and the choice of pelletizing machine depends on the type of plastic scrap material and the quality of pellets needed. The different types of pelletizers include strand pelletizers, underwater pelletizers, and water ring pelletizers.
Strand plastic pelletizing lineThe strand pelletizer cuts molten plastic strands into pellets, while the underwater pelletizer submerges the plastic melt into water to cool and solidify the pellets.
The water ring pelletizer cools and solidifies the plastic melt in a ring of water before cutting it into pellets.
Difference Between Underwater Pelletizer and Water Ring Pelletizer
Water-ring pelletizing machineThe main difference between the underwater pelletizer and water ring pelletizer lies in the cooling and solidification process.
The underwater pelletizer cools the molten plastic in water, which reduces the heat transfer process and allows for a better quality pellet.
The water ring pelletizer, on the other hand, uses a ring of water to cool and solidify the plastic melt.
Advantages of Pelletization

The main advantage of pelletization is the reduction of plastic waste.
Pelletization allows plastics manufacturers to realize their green initiatives by reducing waste and converting scrap plastic into high-quality materials that can be used in manufacturing processes.
Additionally, pelletization allows for easy storage, transportation, and handling of plastic pellets.
Disadvantages of Pelletization
The main disadvantage of pelletization is the cost of the pelletizing system, including the heating and cooling system, transmission system, and extrusion system.
Additionally, third-party services may be needed to attain high-quality materials. However, these costs can be offset by the savings in raw material costs and the environmental benefits of the recycling process.
Feed Size in Pelletization
PET flakes: 8mmThe feed size in pelletization depends on the type of plastic scrap material and the type of pelletizing machine. Generally, the smaller the feed size, the better the quality of pellets produced.
Purpose of Pelletization
The purpose of pelletization is to convert plastic waste into usable clean raw material for manufacturing processes. Pelletization allows plastics manufacturers to reduce their environmental impact by reducing waste and reusing materials.
Difference Between Pelleting and Extrusion
Pelleting and extrusion are similar processes, but they differ in the form of the end product. Pelleting produces cylindrical pellets, while extrusion produces plastic film or other shapes.
Pelleting is ideal for converting scrap plastic into raw material for manufacturing processes, while extrusion is ideal for producing plastic packaging or other products.
Factors that Determine the Quality of Pellets
The quality of pellets is determined by several factors, including the type of plastic scrap material, the type of pelletizing machine, and the heating and cooling system used.
Additionally, the quality of pellets can be affected by the transmission system and the extrusion process. It is essential to work with a reputable plastic pelletizing company that values the quality of their products and the satisfaction of their customers.
Conclusion
When selecting a custom plastic pelletizing system, it is essential to consider factors such as the transmission system, extrusion process, heating and cooling system, and third-party services offered by the manufacturer.
Many plastic pelletizing companies, including Nicety, offer custom plastic pelletizing systems that can be tailored to meet the needs of plastics manufacturers.
