KY SERIES CO-ROTATING TWIN SCREW PLASTIC EXTRUDER

Machine Principle

Twin screw extrusion is used extensively for mixing, compounding, or reacting polymeric material. The flexibility of twin screw extrusion equipment allows this operation to be designed specifically for the formulation being processed. For example, the two screws may be co-rotating or counterrotating, intermeshing or nonintermeshing. In addition, the configurations of the screws themselves may be varied using forward conveying elements, reverse conveying elements, kneading blocks, and other designs in order to achieve particular mixing characteristics.
