Material fluidizing apparatus

Apparatus for fluidizing and intermixing two viscous materials comprising a pair of conduits each having an inlet and an outlet with each conduit carrying one of said viscous materials, a third mixing conduit joined to the outlets of the first said conduits with at least the outlet portions of each of the first said conduits being angularly disposed relative to said third mixing conduit and to the other of said pair of conduits, means for forcing said viscous materials individually under pressure into the inlets of and through each of said pair of conduits, a second pair of conduits each coupled to and communicating with one of the first said pair of conduits and angularly disposed relative thereto for the injection of a compressed gas into the said first pair of conduits and counter to the flow of said viscous materials therethrough, and means for feeding compressed gas to each of said second pair of conduits, whereby said gas will intermix with and fluidize the materials in each of the first said pair of conduits and the fluidized materials will each then enter said third mixing conduit at an angle one relative to the other and to said third mixing conduit and become thoroughly intermixed one with the other in said third mixing conduit.
