  • Keel type ram for use in internal batch mixers with tangential rotors
    Publication number: 20080239866
    Abstract: This invention provides a ram for use in a mixer with counter-rotating non-intermeshing rotors on which the central portion of the ram utilizes a apex, either a point or a line produced by a “V” or similar shape, that protrudes a given distance into the mixing chamber and on which the end portions of the ram are either horizontal such that they do not protrude into the mixing chamber at all or are otherwise shaped such that they protrude into the mixing chamber less than the apex of the central portion of the ram.
    Type: Application

  • Four wing, non-intermeshing rotors for synchronous drive to provide improved dispersive and distributive mixing in internal batch mixers
    Patent number: 6494607
    Abstract: 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.
