Its conveying theory was also studied. It can realize positive conveying in the solid conveying zone. Besides, it can also e the defects that the existing feed bushings have, such as high shearing force, high melt temperatures, which can decrease the solid conveying capacity of the extruder. So it can highly increase the output of the extruder. The works of the paper will play a positive role for designs , studies and applications of single screw extruder.
