ABSTRACT:
A mixing device for preparing wet mix cementitious products comprised of large aggregates includes a pair of generally tubular, horizontally disposed casings which form a mixing chamber, and which share common, open sides. An open top of the chamber receives raw materials to be mixed. Elongated central impeller shafts extend longitudinally, generally coaxially within each of the casings, rotatably terminating in appropriate bearings. A pump impeller assembly removably mounted to each of the impeller shafts includes rigid, spaced-apart spiders having three, integral, radially spaced-apart outwardly extending arm segments. The spider arm segments support a pair of spiralled, spaced-apart mixing rods. A similarly spiralled, outermost resilient wiping blade extends between the outermost portions of the spider segments in spaced relation with respect to the mixing rods and contacts the inner surfaces of the chamber casings in response to rotation whereby aggregates are thoroughly blended to form a uniformly mixed cementitious product.
