The Triple screws of the GSmach series of co-rotating parallel three-screw extruders are arranged in a "one" shape and rotate at high speed in the same direction, subjecting the material to intense shearing, squeezing, kneading and grinding action for better homogenisation and dispersion. Compared to conventional twin-screw extruders, the triple-screw extruder has an additional high shear zone, which doubles the plasticising and mixing performance of the twin-screw extruder, resulting in high output and twice the capacity of the twin-screw extruder. The de-volatilisation efficiency is also significantly higher due to the increased specific surface area and increased surface renewal rate.
