Screw Feeder

May 11, 2009
This screw feeder combines the versatility of flexible hopper technology with a 2-in-1 feed screw option that improves gravimetric batch accuracy. Historically, users have had to choose between speed and accuracy; a screw large enough to provide the desired batch speed also caused feeders to routinely overshoot the set point with varying results. Because the PosiPortion feeder actually uses two independently driven screws, situated one inside of the other, it is capable of delivering precision batches fast.
