摘要

An apparatus (100) for conveying and metering powder (112) comprises a powder storage container (110) for storing and providing powder (112), a vibratory conveyor (120) having a conveying device (122) with an adjustable conveying rate for delivering the powder (112) at the adjustable conveying rate to a powder outlet (124), a line arrangement (130) for transporting the powder (112) delivered by the vibratory conveyor (120) in a conveying gas (115) as a powder-gas mixture (116) and for feeding the powder-gas mixture (116) to a powder processing device (200), wherein a coupling-out device (132) is provided in the line arrangement (130) in order to remove a defined proportion PM2 of the powder (112) from the powder-gas mixture (116), a powder quantity measuring arrangement (140) for recording the quantity of powder PM2 coupled out per unit of time and for providing a powder quantity information signal S1, wherein the quantity of powder PM2 removed per unit of time is in a prescribed ratio to the conveyed quantity of powder PM1 of the vibratory conveyor (120) within a tolerance range, and a control device (150), which is designed to adjust the adjustable conveying rate of the vibratory conveyor (120) to a prescribed setpoint value on the basis of the powder quantity information signal S1 provided by the powder quantity measuring arrangement (140).
