2 Description With automatic mass flow control ThedosingunitontheBEG2000iscontinuouslyweighedforautomaticmassflowcontrol.ThedatafromatouchscreenPC are continuously acquired and analyzed via a serial interface. As a result, the dispersed quantity of powder is always known and able to be automatically adjusted. Dosing output on the controlled using internal firmware Inputofthemassflowing/h Automatic mass flow control Recording of powder-specific calibration curves ExternalcontrolviaPCorModbusRTU Network-compatible Function Thepowdertobedispersedissimplypouredintothereservoir(seeFig.1).Astirreratthebottomofthereservoirensures uniform loading of the conveyor belt. A rabble arm and various built-in components in the reservoir prevent bridging in the reservoir. Fig. 1: Principle of operation of the BEG 1000/ Dosing The desired mass flows are able to be continuously and reproducibly adjusted with a controlled drive on the conveyor belt The even, smooth conveyor belt, the built-in components in the reservoir, and the precise drive on the conveyor belt ensure excellent dosing constancy. Automatic readjustment is possible up to approx. 100 g/h. Page2of6

3 Pulsed operation The system can be operated in"powder"/"no powder" pulse mode with the"stop" and "Belt"controlkeysandanelectrictimerswitchincyclesofupto5sec,dependingonthemassflow. Dispersing The ejector nozzles we developed provide excellent dispersion for various volume flows. Page3of6
