Adopt the new generation of solid-liquid phase separation screw technology. The screw is composed of multiple sections, including the forced feeding section, the melting solid-liquid phase separation section, the combined flow plasticizing section, the homogenization section, and the forced mixing section. The screw adopts a large length-to-diameter ratio design, 33-38:1. The screw barrel is designed with an extended forced feeding system. The inner wall of the screw barrel is provided with feeding troughs of different structures to ensure the rapid compression and advancement of materials. The extended forced cooling system is connected to the high-temperature screw cylinder by flange, and a gap of 1-3MM is left to prevent heat from being conducted to the feeding section and ensure the rapid, high-pressure and low-temperature advancement of the material. The speed ratio of the reducer adopts a design of 16-8:1 to ensure the high rotational speed of the screw. Combined with a high-power kinetic energy system, it achieves high speed and high efficiency. The production efficiency is 30% higher than that of ordinary screws, and the heating energy consumption is reduced by 20%. This system has the advantages of high efficiency and high speed, high extrusion volume, good yield, long service life, and stability and reliability.
