Large screw kneader method and large screw kneading

摘要

The present invention relates to a method for manufacturing a large-sized kneading screw, in which a plurality of screw pieces cut to a predetermined thickness from one side of a kneading screw to be manufactured are successively joined to an outer circumferential surface of a rotating shaft, Thereby making it possible to easily manufacture a large kneading screw and to provide a large kneading screw size to a user in a desired size so as to improve the productivity of the kneading screw and to improve the productivity of the kneading screw So that the twist angle of the screw can be adjusted.
