Abstract
A device (1) for feeding a processing device with powdery material (2) comprises a first chamber (3) having at least one fluidizing device (5) configured to fluidize and/or to potentially fluidize the powdery material (2), at least one second chamber (6) being in connection with the first chamber (3) such that fluidized and/or potentially fluidized powdery material (2) is transportable from the first chamber (3) into the second chamber (6), and at least one third chamber (9) being in connection with the second chamber (6) such, that the potentially fluidized powdery material (2) is transportable from the second chamber (6) into the third chamber (9). The device (1) is configured to defluidize the powdery material (2) such that it is present as defluidized powdery material (2) in the third chamber (9). The third chamber (9) has a discharge element (10) configured to discharge the defluidized powdery material (2).
