Four wing, non-intermeshing rotors for synchronous drive to provide improved dispersive and distributive mixing in internal batch mixers

摘要

Four wing rotors for used in an internal batch mixer. The rotor has two long wings, and these two long wings have different approach angles and helix angles. The rotor has two short wings and these short wings also preferably have different helix angles and approach angles. The rotors provide improved distributive and dispersive mixing allowing for greater productivity in processing materials and producing more homogeneously mixed materials at lower discharge temperatures.
