Feeder combines speed with accuracy

November 23, 2009

Flexible hopper feeder with an innovative 2-in-1 feed screw option improves gravimetric batch accuracy. Historically, users had to choose between speed and accuracy. A feed screw which was large enough to provide the desired batch speed also caused feeders to routinely overshoot the set point with varying results. However, this feeder uses two independently driven screws, situated one inside of the other, and is capable of delivering fast precision batches.
