Model PF-S-6 Powder Feeder

February 5, 2013

The Model PF-S-6 Powder Feeder is designed for the precise feeding of cohesive, easily aerated, and difficult-to-control powders. It handles a wide range of material bulk densities at low to medium feed rates. The feeder’s patented system assures reliable metering, and the patented Thayer Scale U-Trough hopper and feed section provides a practical and economical means for metering difficult powders. The geometry of the trough and agitator effectively de-aerate and contain the powder on initial fill to help prevent flooding. The independently driven agitator maintains optimum material conditioning while screw speed can vary to control flow rate. Material does not build up within the trough or within the continuous screw tube, preventing blinding or erratic feed. This combination along with a vast selection of screw sizes and types allows material to be fed with an accuracy of ±1.0 to 2% of set rate.
