COAXIAL FEEDING, METERING AND MIXING AUGER-CONVEYOR MIXER

摘要

Abstract of the DisclosureMixing apparatus is disclosed for the continuous production of mixedmortar, cement or the like from a dry mortar cement or like material suppliedto the apparatus and water mixed therewith inside the apparatus. The drymaterial, in operation, is conveyed by means of a metering screw through ametering channel into a mixing chamber where the water is added. Scoops orlike blades which project radially beyond the outer periphery of the meteringscrew are arranged over at least part of the length of the metering screw.Preferably, the scoops have an inclination opposed to the pitch of the meteringscrew, the scoop surface intersecting the thread of the screw approximately atright angles.
