Extruder is one of the main plastic machinery,which accounts for 31% of GDP and plastics products which is produced by Extruder take up 1 / 3 of its total. Single-screw extruder, whether as a plastic pelletizer or molding plastics processing machinery is all playing an important role.In recent years, single-screw extruder has developed to study more mature. Twin-screw extruder is widely used in various fields of plastic Industries as a result of good properties for powder processing, and have superiority of mixing,exhaust,response and self-cleaning function,which is better than single screw extruder.Three screw- extruder has just begun its R&D in China because of the complex structure.However,Beijing Zhongxing New-made Plastic Machinery Co.,Ltd.has successfully developed a three-screw extruder which is not only easy to feed, no lack of material of vacuum hole, the material remaining short, high yield and low consumption, but also has perfect mixed plastic effect.This extruder is the first model in China.

     A unique "internal mixer type" three-screw extruder, is the new style of 21 century, its coming out has filled the  gap in the world, which will be bound to produce a technological revolution for extruder industry and become the main force of plastic industry equipment.

 

     At present,this machine is 60 style,three screw were down with "goods"-type arrangement.Screw diameter is 60 mm, center distance is 54 mm, l/d ratio is 22:1, the screw speed is 500 / minute and the main electric power is 55KW.Frequent speed adjustment as well as DC speed adjustment are adopted and unique water loop heat device is matched.
