Three-screw extrusion pelletizing line adopts isotropic parallel combination of three-screw structure, to achieve in the smaller screw L/D ratio conditions can be achieved in the traditional twin-screw extruder in the larger L/D ratio can be achieved mixing and blending effect, has a unique high filler, high dispersion, yield, low energy consumption advantages, can be widely used in plastic mixing and modification, filler modification, dispersion of auxiliaries, fiber reinforcement, blending, polymerization reaction, Exhaust degassing and other processing fields.
Product Performance.
1, three-screw extrusion pelletizing line of the same parallel three-screw extruder has two kneading area, compared with the twin-screw extruder, has more excellent transportation, self-cleaning, exhaust, mixing and dispersing effect.
2、The weight ratio of filling is 65% carbon black powder and 35% plastic granule, and higher ratio can be challenged.
3, carbon black powder and plastic particles are measured by high-precision loss-in-weight weighing, powder measuring accuracy of 8%o, plastic particles measuring accuracy of 5%o, to achieve the precise proportion of two or more components of the material.
4、Optimized screw combination structure ensures the transportation stability of highly filled carbon black powder and improves the mixing and homogenizing effect.
5、Special exhaust screw structure, suitable for PC, PMMA and other crushed materials.
6、Co-parallel three-screw extruder is driven by high torque motor.
7、Pelletizer is driven by high power frequency conversion motor, which provides strong dynamic, and equipped with strong and sharp knives, especially suitable for water-cooled pulling strip pelletizing of hard plastics.
Typical applications.
After pelletizing, single screw extrusion and calendering composite line is used to prepare PPTC self-recovery fuse original piece.
