Double screw extruderWhen processing materials, screws are used inside the cylinder to complete conveying, mixing, and pumping. The modularity of the cylinder facilitates segmented transportation of individual units along its length. The material barrel adopts electronic heating and liquid cooling methods, and serves as an independent temperature control zone. The segmented components are combined on a high torque shaft to optimize the screw configuration according to process requirements. The typical length to diameter ratio (L/D) that can be used for reactive extrusion and/or multi-stage solvent removal ranges from 32 to 48:1, with a maximum of 60 L/D (or longer). Electric energy is converted into mechanical energy through a transmission system (motor gearbox), and then the material is sheared by a rotating screw.
The modular cylinder and segmented screw have controllable wiping and pumping characteristics, allowing people to adjust the geometric configuration of the screw and barrel to match the requirements of the process task. Solid transportation and plasticization usually occur in this preparation process. Mixing, downstream feeding, liquid injection, and ventilation are commonly used, and their principles are determined by the process. The structural configuration range of screws includes both shear sensitive and shear passive types.
