The volumetric version of the gravimetric ProFlex C feeder can be used to feed additives and fillers in powder, granulate or fiber form. The system requires no maintenance, and is available in two feeder sizes and three container sizes. Up to eight feeders can be installed in a very compact space to form one complete feeder station as the augers are positioned off center. Two discharge lengths are available for feedrates up to 9,500 dm3/h. — Schenck Process GmbH, Darmstadt, Germany
