IMPROVED DRUM FOR TILT MIXER An improved tiltable rotating concrete mixing drum has a relatively flat rear conical charging zone, a front conical zone having a central discharge opening for discharging materials when mixed and a generally cylindrical central zone disposed between front and rear conical zones in which the overall length-to-diameter ratio is reduced. The improved mixing drum has two sets of mixing blades, one in the central or mixing zone and one in the front or discharge zone which is scoop-shaped and configured to increase the efficiency of mixing along the horizontal axis of the drum by increasing the overall mixing efficiency.
