Abstract
The internal batch mixer with three-wing non-intermeshing rotors includes a pair of non-intermeshing, counter-rotating, tangential rotors each having three wing portions. The internal batch mixer includes a housing defining a mixing chamber, where the mixing chamber includes first and second substantially circular chamber cavities in open communication with one another at a central region of the mixing chamber. The first and second non-intermeshing, counter-rotating winged rotors are respectively rotationally mounted within the first and second substantially circular chamber cavities, such that the central region of the mixing chamber defines an interacting mixing region between the first and second non-intermeshing, counter-rotating winged rotors. The first and second non-intermeshing, counter-rotating winged rotors are driven to counter-rotate with respect to one another. Each rotor has a substantially helical contour and a blade portion divided into three separate wings.
