What is the reason for the popularity of plastic granulators?

The plastic granulator mainly crushes the PP plastic waste and extrudes it into strips by heating and melting. Then it is cooled and molded into a machine for cutting into granules. The machine generally consists of feeding machine, screw extruder, automatic pelletizer and automatic temperature control system.

How does the plastic granulator make the product?

The plastic granulator is designed to mechanically extrude the mixture of PE and PP. The process is to first crush and dry the PE or PP powder, feed it to the extrusion unit and mix it completely with polypropylene (modified polypropylene), and then pass it through the plastic granulator. The screw rotates under the action of high temperature and high pressure to melt it and extrude, cool and shape the material from the nozzle, and finally cut into particles of the desired length.

What is the reason for the popularity of plastic granulators?

The plastic granulator adopts special screw design and various configurations, and is suitable for regeneration and color mixing granulation of various plastics such as PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, PMMA, etc. The reduction gearbox adopts the design of high torque, which realizes the performance of silent and smooth operation. The screw and cylinder are specially hardened, which is characterized by wear resistance, good mixing performance and high performance. The design of the vacuum outlet or normal outlet opening can dissipate moisture and exhaust gases during the production process, allowing the material to dissipate. It is more stable and the colloidal particles are stronger, which ensures the good quality of the product.

The plastic granulator is mainly used for processing plastic film waste (industrial packaging films, agricultural plastic films, greenhouse films, beer bags, handbags, etc.), woven bags, agricultural convenience bags, basins, barrels, beverage bottles, furniture and daily needs etc. Applicable to most common plastic waste, it is the most widely used, most widely used and most popular plastic recycling processing machine in the plastic recycling industry.

Why does a plastic granulator need temperature control?

The plastic extrusion of the temperature control wire and cable insulation and sheath of the plastic granulator host is carried out in a viscous flow state according to the deformation properties of thermoplastics. In addition to the requirement of external heating of the screw and cylinder, which is transferred to the plastic for melting and extruding, the heat generated by the screw itself when extruding the plastic is also required. Therefore, the temperature of the host should be considered as a whole, including opening and closing the heater. It is necessary to take into account the factor of extrusion heat overflow of the screw to cool it, and there must be effective cooling devices. And it is necessary to correctly and appropriately determine the position and installation method of the thermocouple of the measuring element, so that the actual temperature of each section of the host can be accurately reproduced from the display of the temperature control instrument. And the accuracy of the temperature control instrument must be well matched to the system, so that the fluctuation stability of the entire host temperature control system can meet the extrusion temperature requirements of various plastics.
