Request Quote

		Gravimetric Feeders Dosing Screw Select FlexWall® except where: • Ingredient responds best to an internal agitator • All SS ingredient contact is required • Some explosion proof (NEC hazardous environment) needed • Ingredient temperature above 80°C continuous • Powder feed rates below 1 lb/hr. (to 50 grams/hr.) Features: • Positive internal agitator positioned above screw(s) • Separate drive motor for agitation on larger feeders • AC motor(s) with VFD for screw drive • Mass flow extension hopper • Twin concave screws are self-wiping • Screw is below agitator, no ingredient heel below screw Request Quote

		Gravimetric Feeders Vibratory Tray Select where a screw feeder is not preferred: • High bulk density ingredients • Abrasive ingredients • Chips and irregular shaped ingredients • Plastic pellets "pulsationless" flow/wide range • No sear on ingredient Features: • Rate stable with varying load (amplitude feedback and resonant frequency control) • No rotating shaft seals to wear • Wide feed rate range with electronic adjustment • Tray covered with see-through plexiglass • 304 SS contact metal parts Request Quote

		Gravimetric Feeders Silo Tray Select for feed rates above 30 cu.ft./hr. and for large feeder storage: • Wood flour • Chopped plastic film (flakes) • Batching with no offset, feed from center line of hopper Features: • Live bin bottom activation of bin contents for optimal flow • Center baffle splits flow to 4 internal trays, prevents bridging • Linear horizontal vibration induces flow in trays • Entire bin bottom induces controlled flow • VFD on vibration motors varies flow • Storage with circular vertical walls Request Quote

		Gravimetric Feeders Liquid Select for liquid feeding in conjunction with dry feeders or for very precise liquid feed: • Continuous feeding of liquids requiring precise feed rate control Features: • Liquid tank weighed, pump not weighed to ensure discharge piping does not affect weighing • Suction line has flexible and horizontal section to provide transition from weighed tank and pump • High feed rate precision even at low feed rates (eg: 30 grams/hr.) Request Quote
