Aperfeicoado apparatus for mixing materials including solid ingredients which become gelatinous at temperatures above ambient temperature

摘要

Internal or closed chamber high shear mixing apparatus for compounding materials including solid ingredients which become gelatinous at temperatures above ambient temperature, such as, rubber, elastomer, plastic, and like mixes, in a continuous manner having parallel material processing rotors in side-by-side communicating chambers closed except for a material feed opening adjacent one end and a material discharge opening adjacent the other end, the latter opening communicating with a screw controlled discharge aperture directly communicating with the rotor chambers of extensions thereof and offset from and extending transversely of the axes of rotation of the rotors. Each rotor comprises high helix angle mixing blades preceded by a feed screw.
