With special screw design and different configurations, it is suitable for the production of PP, PE, PET, PS, ABS, PA, PVC, PC, POM, EVA, PMMA and other plastics regeneration and color mixing granulation. Reducer adopts high torque design, low noise and smooth running performance. Screw, barrel after special surface treatment, with wear resistance, mixing effect is good, high yield characteristics. The design of vacuum exhaust or natural exhaust port can remove water and waste gas in the production process, so that the material is more stable and the colloidal particles are more dense to ensure the excellent quality of products.
