Application of Plastic Flake Pelletizing Line
Our rigid plastic pelletizing line is suitable for recycling various types of plastics, including PP, HDPE, PVC, ABS, PS, PC, and so on. It can not only recycle post-consumer plastics but also process the trimmings and wastes from post-industrial plastics into high-quality granules, which can be used again for the production of plastic products.
For example, our equipment can recycle plastic buckets, plastic bottles, plastic baskets, food containers, electrical shells, car parts, garbage cans, toys, bottle caps, and many other plastic products. If you have the above or other plastics to recycle, you can contact us anytime, our professional sales manager can provide solutions according to your raw materials.
Plastic Granulating Line Process And Related Machines
In the first step of the plastic granulation line, the plastic needs to be crushed using a plastic shredding machine to crush the large plastic material into small pieces suitable for subsequent processing.
The blade of this shredder machine is made of 60Si2Mn, which is sturdy and durable. The screen size is 20-26mm to control the sheet size.
The crushed plastic flakes will enter the plastic chips washing machine, in which the residual impurities, dirt, etc. will be cleaned off to ensure the purity and quality of the plastic.
The cleaned plastic pellets go to the horizontal dryer to remove the water from them by drying to ensure that the subsequent extrusion process can be carried out smoothly and to avoid the influence of water on the quality of the granules.
The centrifugal dryer has a drying rate of 98% and, if fitted with drying pipes, can control moisture to less than or equal to 0.5%-1%.
The cleaned and dewatered plastic granules are then fed into a waste plastic granulator, where the plastic is heated and melted, and then extruded through an extruder mechanism, where the melted plastic is extruded into a continuous strip.
Plastic Cooling Tank
The extruded plastic lengths are fed into the plastic cooling tank, where they undergo rapid cooling, allowing the plastic pellets to solidify quickly and maintain their shape and size stability.
The cooled plastic lengths are then cut through the plastic granule cutter, which cuts them into lengths of plastic pellets for subsequent packaging, transportation, and use.
The machine adopts a carbide hobbing knife and cuts out a granule size of about 3mm.

We configure the corresponding type of equipment according to different output requirements. In addition to the recycling machines in the above table, customers can also configure auxiliary equipment such as strip-blowing machines and vibrating screens according to their needs.
Strip blowers are usually installed behind the cooling tank to blow dry the water on the plastic strips while vibrating screens are installed after the plastic granule cutter to screen out unqualified pellets to ensure the quality of the final product.
Strand Pelletizing And Water Ring Pelletizing
In the field of plastic granulation, strand pelletizing, and water ring pelletizing are two common and efficient pelletizing systems. Stand pelletizing systems work by extruding molten plastic into strips, which are cooled and then cut into uniform pellets. This method is suitable for a wide range of plastic materials, is easy to operate, and provides consistent granule quality.
Water ring pelletizing systems, on the other hand, cut the molten plastic into granules directly in the water ring after it has been extruded and subsequently cooled and dried. The water ring pelletizing system has a higher degree of automation and is suitable for handling high-viscosity plastics with high production efficiency and uniform pellet shape.
Both granulation methods have their advantages, and customers can choose the most suitable pelletizing method according to their production needs and material characteristics to optimize production results and improve product quality.
