Abstract
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.
