ABSTRACT:
An improved and more rapid mixing of concrete is achieved in a rotary concrete mixing drum according to the present invention by the simple expedient of providing passages which open through the body of the mixing blade which permit concrete flow therethrough. The flow of concrete through the passages creates added turbulence in the body of concrete during the rotation of the mixing drum in the mixing direction. The concrete is prevented from passing directly through the same mixing passages when the mixing drum is rotated in the discharged direction by mounting deflector blades on the discharge face which extend over the mixing passages and deflect the concrete aggregate away from the mixing passages during rotation of the mixing blades in the discharge direction.
