An apparatus for mixing pulverous solids into a liquid phase substantially consists of a gas-tight mixing vessel (10), a solids metering means (12), and a pumping means (14). Gas used for pneumatic conveyance and becoming enriched with liquid in the mixing vessel (10) is aspired by the pumping means (14) and recycled to the solids metering means (12) through a return conduit (54). At least one condenser (58, 66) is arranged in the return conduit (54) to eliminate the liquid so that the liquid contained in the gas is largely condensed off and its sticking to the solids to be metered is avoided. The operation of the apparatus and the corresponding method are to the greatest extent possible free of emissions.
A method of mixing pulverous solids into a liquid phase, wherein the solid material is metered pneumatically into a mixing vessel (10) containing the liquid phase, and a gas phase located above the liquid phase is aspired by a pumping means (14), characterized in that liquid contained in the gas phase is condensed off, at least partly, at a location remote from the pumping means, and the gas phase is recycled into the mixing vessel (10) in a closed gas circuit through a solid metering means.
An apparatus for mixing pulverous solids into a liquid phase, comprising a gas-tight mixing vessel (10) in which there is at least one mixing member (22, 28), a solids metering means (12) connected to the mixing vessel (10), and a pumping means (14) whose suction end communicates with a gas phase contained in the mixing vessel above the liquid phase, characterized in that
