Use of plastic granulator screw recycling line pelletizing machine

For plastic recycling washing line pelletizing machine

The ratio of the three sections of different screws is different, the depth of the screw groove is different, the transition form of the screw bottom diameter is different, and the three sections of the screw of the plastic granulator have different functions and uses:

(1) Feeding section: This section has a fixed depth of the groove and is used for preheating and plastic solid conveying and extrusion. The plastic begins the melting process at the end of the feed section.

  (2) Compression section: This section is the taper depth of the tapered screw, which is used for melting, mixing, shear compression and pressurized exhaust of plastic raw materials. The plastic will completely dissolve in this section, the volume will shrink, and the compression ratio design is very important.

(3) Homogenization section: This section is the screw groove fixed groove depth. Its main function is mixing, melt conveying, metering, and sufficient pressure must be provided to maintain the uniform temperature of the melt and stabilize the flow of molten plastic.
