Abstract : Apparatus for mixing viscous, curable liquid materials in which the components to be mixed are fed at high pressure (up to 5000 psi) into the central longitudinal chamber of a mixing head. The inlet ducts are on opposing sides of the chamber and displaced longitudinally so that there is no mixing of the components in the upstream end of the chamber where the drive shaft enters the mixing head. The two components are forced from the chamber through rotating apertures into a rotating inner tube (rotating at up to 500 RPM). The end of the rotating inner tube is closed so that the high pressure forces the material through a multiplicity of apertures in the wall of the tube. The rotating tube is enclosed in a concentric stationary tube having a multiplicity of apertures in its walls. The material is forced through the second group of apertures into an annular outer chamber which leads to the output of the mixer. A final stage of mixing may be provided by forcing the mixture through a set of apertures and around some baffles to exit into an outlet duct through a plurality of apertures.
