Plastic scrap recycling is an efficient and cost-effective way to reuse the high-quality materials produced from manufacturing plants. In order to turn these scraps into usable pellets, companies like Accel Polymers utilize advanced plastic pelletizing machines. These machines combine cutting, extrusion and granulating into one process to produce high-quality plastic pellets. By utilizing this technology, manufacturers can increase their profitability and improve their green initiatives.

The machine consists of conveyor belt, cutter, compactor, shredder, pelletizer and cooling system. With different internal screw systems, the machine is suitable for a variety of raw materials. It can also be equipped with a dewatering machine and an air dryer to make the pellets dry and clean. The pellets can then be transferred into a silo for storage.

Twin-screw extruder

The twin-screw plastic pelletizing machine is used for plastic modification, plastic compounding and masterbatch production. It is suitable for a wide range of raw material, such as PE, PP, PS, PMMA, ABS and others. The machine is easy to operate and requires minimal maintenance. It has a high torsion and low noise, making it ideal for continuous operation.

This plastic pelletizing machine uses a compression barrel and rotatory blades to crush and compact the incoming material. The frictional heating caused by the rotatory blades heats the shredded scraps to just below their agglomerating point. This allows the shredded plastic to shrink into pellets that can then be melted and shaped by the extruder screw. This type of plastic granulating machine is able to produce high-quality pellets with a relatively small volume of energy.

It can be designed to cut the molten pellets into various shapes, such as water-ring cutting, under-water cutting and hot face cutting. In addition, it can also be equipped with a cooling system, an exhaust and a drying device to ensure the quality of the finished products. It can also be configured based on the specific requirements of the customer.

Generally speaking, the pellets produced by this machine are of high quality and can meet the requirements of a number of applications. However, if the pellets are to be used in the production of medical devices or automotive components, they may need to undergo additional processing. This is because the mechanical strength of the pellets obtained by powder agglomeration and shot peening are often not sufficient for these applications. To achieve a higher mechanical strength, high-strength binders must be added to the pellets before they are extruded into a mold.

Compared with the traditional methods, this plastic pelletizing machine has the advantages of high efficiency, low power consumption and stable operation. It is equipped with a double degassing screw extruder, which can effectively filter out the impurities in the raw materials and ensure the stability of the output. Moreover, it has an automatic water-ring cutting machine with self-adjusting cutting head, and the rotation speed of the blades is controlled automatically based on melt extruding pressure. In this way, the pellets are more even in shape and have good agglomeration strength.
