PF-S Volumetric Powder Feeder

• Feeds difficult powders such as Cabosil®, TiO2 and other pigments without bridging or clogging the hopper or the screw.
• Exclusive trough design defeats flooding by dissipating kinetic energy of material stream at initial fill.
• Agitator and screw overwind prevent material compaction or arching over screw flights.
• Feeder disassembles easily for total cleaning, eliminating contamination problems when changing materials, (Download PDF)

Proven ability to feed difficult powders

PF-S Volumetric Powder Feeder controls both flooding and clogging problems associated with difficult-to-handle powders. Unique feeder trough effectively de-aerates and contains the powder at the initial fill cycle to prevent flooding. Independently driven agitator maintains optimum material conditioning while screw speed can vary to control flow rate. Material does not build up within the continuous screw tube liner, preventing binding or erratic feed.
