Abstract: Mixing elements comprise curved blades (3,4) connected by crosspieces (5). Axial bars (6,7) are fitted to the faces of the blades. The spacing of the blades is increased and the number of blades and bars (6,7) is decreased towards the outlet end of the vessel. Mixer for materials whose viscosity increases in reaction path. The material is a polymer from which solvents and monomers are evaporated in a heated vessel. A set of non-symmetrical mixing elements are driven by shafts (2,2'), disposed at right angles to each other. Product is fed into the top of the vessel at one end and removed at the bottom at the other end. Fumes can escape at an outlet at the top, opposite the outlet stub. Mixing elements consist principally of curved blades (3,4) connected by crosspieces (5). Axial bars (6,7) are fitted to the faces of the blades. The spacing of the blades is increased and the number of blades and bars (6,7) is decreased towards the outlet end of the vessel to accommodate the increased viscosity of the material as the volatile components are driven off. Preferred Features: The operation of the mixer is one of spreading the material over a large area to assist evaporation rather than to combine materials. Shafts (2,2') are driven at the same speed, in the same sense.
