Abstract

The apparatus for conveying finely powdered material from a reservoir includes a suction/pressure unit that projects into the reservoir. A gas is introduced into the suction/pressure unit and is mixed with the finely powdered material that is sucked into suction/pressure unit from the reservoir to form a powder/gas mixture and this mixture is discharged. Compressed air blows into the reservoir in a finely dispersed manner to fluidized the finely powdered material so that the extraction of the finely powdered material from the reservoir is facilitated.
