Twin Screw Compounding Extruder Screw Element In Screw Barrel

The screw elements is one of the most important part of the twin screw extruder. Its quality will affect the finished plastic
granules quality directly. Part of screw elements are used for feeding and conveying plastic material. and the kneading block will achieve the function of plasticization, mixing and dispersion.
For different plastic material, the screw elements combination can be adjusted to meet different demands of mixing, shearing, dispersion and dying effect.
