Abstract

A heating kettle for melting and mixing thermoplastic resin into a homogeneous mixture, which has a A spiral stirrer located on the inner wall of the kettle that rotates around a central axis. A set of radially extending stirring blades is fixed on a shaft located approximately in the center of the kettle. As the stirrer and stirring blades rotate, which have opposite pitches, the resin circulates along the walls of the kettle and flows through the central area of ??the kettle. This circulation causes all the resin to melt and mix into a uniform liquid substance.

Claims
