Disclosed is a device for the continuous gravimetric metering and pneumatic conveying of pourable material which is conveyed across a given distance by a metering rotor (1) which is arranged in a pressure-proof manner in a housing (2) and is provided with conveying pockets (1a). Said housing (2) comprises a charging station and a discharging station for the pourable material, which are connected to the inlet/outlet (4, 5) of a pneumatic conveyor system. The housing (2) is connected to a force metering device which detects the momentary load generated on the metering rotor (1) by the conveyed material. The inlet and outlet of the pneumatic conveyor system are connected to the bottom of the housing (2). In order to build the inventive device in a compact manner while reducing the assembly requirements and improving flow guidance, the flow from the inlet (4) to the outlet (5) is deflected within the upper area of the housing (2).
A device for continuous gravimetric metering and pneumatic conveying of pourable material, which is guided using a metering rotor, positioned pressure-tight in an enclosed housing and provided with conveyor pockets, over a measuring length, the housing having a pourable material delivery station and an emptying station having respective connections to feed/removal lines of a pneumatic conveyor system and being connected to a force measurement device, via which the torque load exerted on the metering rotor by the material conveyed may be determined, and the feed line and removal line of the pneumatic conveyor system being connected to the bottom of the housing,
