single screw extruder
machines has one screw rod and Twin Screw Extruder machines has two , both of them are driven by a motor . The power is different
Single screw extruder as plastics granulator machinery or molding processing machinery occupies an important position in the industry, in last few years, single screw extruder had very great progress. The screw diameter of the large single screw extruder of German is f 700mm.
Twin-screw extruder machine feeding characteristics for powder processing, and better mixing, exhaust, response and self-cleaning function than the single-screw extruder, is characterized by the processing of poor thermal stability, plastics andblends also show its superiority. In recent years foreign twin-screw extruder has been greatly developed, and various forms of twin-screw extruder has been serialized and commercialization,
Except the two kind of extruder , there are sheet production extruder
