Double screws are essential for improving material mixing and processing in extrusion machines. They operate in sync to ensure a homogeneous mixture, which optimizes the efficiency and quality of the final product in various industrial applications.
There are two types of twin screw extruders: In corrotators, both screws rotate in the same direction, facilitating an intensive and uniform mixing of materials, which allows a homogeneous distribution of additives and pigments, this configuration also favors a higher production capacity. On the other hand, in counterrotators the screws rotate in opposite directions, better controlling the flow and mixing of materials, ideal for sensitive products or requiring precise mixtures, allowing more fine adjustments in the process, in addition to that they have a lower energy consumption.
Double screw extruders have evolved since their initial invention in 1869, offering significant improvements today.
