An apparatus and method of mixing concrete include a horizontally cylindrical mixing drum being loaded with concrete ingredients, agitating the ingredients by way of mixing elements rotating about a horizontal axis centrally located with respect to the mixing drum, rotating the mixing drum about the axis, such that an opening in the mixing drum is revolved to a horizontal elevation below the axis, and discharging the mixing drum by rotating the mixing element such that the mixing elements urge the contents thereof in the direction of and through the opening.

A mixing apparatus, comprising: a horizontal mixer support platform; two spaced shaft supports extending upwardly from the mixer support platform; a bearing fixed to each shaft support at a location spaced above the mixer support platform; a shaft extending between the bearings and being supported thereby for rotation about a horizontal axis; a plurality of arms fixed to the shaft and extending radially therefrom for corotation with the shaft; mixing blades fixed to the arms; power means for causing controlled rotation of the shaft, arms and blades; a mixing drum defined by two disk-shaped end plates and a substantially tubular intermediate member between the end plates and having exterior and interior walls being cylindrical about a central axis; the shaft extending through central apertures in the end plates such that the mixing drum central axis is coaxial with the shaft; the arms and blades and an intermediate portion of the shaft being enclosed by the interior walls of the mixing drum; the bearings being exterior to the mixing drum; the mixing drum being rotatable about its central axis between a first position for loading the mixing drum and a second position for discharging the mixing drum; and the mixing drum being supported by drum support means for supporting the mixing drum, the drum support means being fixed to the mixer support platform, such that the mixing drum is substantially entirely supported by the drum support means, with the shaft, arms and mixing blades being substantially entirely supported by the shaft supports.
