Features of plastic granulator:
After the plastic is added to the hopper of the plastic granulator, it falls smoothly from the silo to the screw of the extruder, and is bitten by the external thread of the extruder screw. Along with the rotation of the extruder screw, the external thread is forcibly pushed to the direction of the engine. It constitutes the whole process of transportation of machinery and equipment. When the plastic is running from the feeding port to the engine, because the depth of the external thread of the extruder screw gradually decreases, and because of the existence of frictional resistance such as the filter screen, the separation plate and the engine, a high work is produced in the whole process of plastic melting. The pressure can compress the raw material very densely, which improves its thermal conductivity, which is conducive to the rapid melting of the plastic. In addition, the working pressure is gradually increased so that the vapor originally stored in the middle of the pellets can be discharged from the exhaust hole.


In addition to the increase in working pressure, on the one hand, the plastic is heated by the outside world, and on the other hand, during the whole process of shrinking, cutting, and mixing the plastic itself, a lot of heat is also caused by the internal sliding friction. Under the synergistic effect of , the temperature of the plastic gradually increases, and its physical condition also undergoes a transition from a glass state to an elastic cotton state to a viscous flow state.







The basic principle of plastic granulator:
The server of the plastic granulator is a flame-retardant plastic system, which consists of extrusion molding system software, transmission device and heating and cooling system.

Plastic granulator extrusion system software: The extrusion system software includes the extruder screw, barrel, silo, engine, and abrasive tool. The plastic is melted into a uniform solution according to the extrusion system software, and is here A working pressure created throughout the process is continuously extruded by the extruder screw.




1. Extruder screw: It is the most important component of the plastic granulator. It is directly related to the application range and productivity of the plastic granulator. It is made of carbon steel with high toughness and corrosion resistance.


2. Barrel: It is a metal material seamless steel tube. Generally, carbon steel with high temperature resistance, high compressive strength, firm wear resistance and corrosion resistance or composite seamless steel pipe lined with carbon steel is used. made. The plastic granulator barrel and the extruder screw cooperate with each other to complete the crushing, softening, melting, melting, exhausting and compacting of the plastic, and the plastic pellets are continuously and uniformly transported to the forming system software. Generally, the length of the barrel is 18:1 to its diameter, so that the plastic can be sufficiently heated and melted as the standard.


3. Silo: The bottom of the silo is equipped with a disconnecting device, which is convenient for adjusting and disconnecting the material flow. The side of the silo is equipped with a sight hole and calibration measurement and verification equipment.


4. Engine and abrasive tool: The engine is composed of an alloy steel inner sleeve and a carbon steel outer sleeve, and the engine is equipped with a forming abrasive tool.
