Mixing device for embedding biologically harmful wastes in a solidifying binder, includes a tubular housing, an assembly of a pre-mixer, a pass-through mixer and a discharge pump having rotatingly movable parts disposed along a common rotational axis and in substantially vertical direction within the tubular housing, and a drive motor mounted at the upper end of the assembly for rotating the movable parts in common, the movable part of the pre-mixer being centrically disposed in the housing, and the movable part of the discharge pump being eccentrically disposed with play in the housing.

Mixing device

Apparatus for the conditioning of radioactive wastes capable of ultimate storage, using a multicomponent binding agent, with a continuous-flow mixer, a filling station for the ultimate storage barrels, a receiver tank for liquid waste materials, a silo for a component of the binding agent, and several conveyors. A premixer for the one binding agent component and for flowable waste materials is provided. The premixer is connected via throughput measuring devices to the silo and to a container for flowable wastes. The premixer is connected via a dosing conveyor device to one end of the continuous-flow mixer. Thereafter, the receiver tank is connected to the continuous-flow mixer. A discharge conveyor device which feeds the ultimate storage barrels is mounted at the other end of the continuous-flow mixer.
