Volumetric feeder

worm screwrotarypowder

Volumetric feeding systems use an auger or screw conveyor running at a constant speed to discharge powder from a storage hopper at a consistent rate (volume per unit time - eg litres/min.) Frequently the hopper includes devices to condition the bulk material to ensure an even bulk density by using vibration, agitation, massaging, or other means to eliminate air pockets and maintain flow. A wide variety of screw designs are used by GEA Nu-Con to suit each particular application: Single Screw Twin Screw Half Pitch Flighting Double Pitch Flighting Open Flight Helixes Side/Top Discharge Nozzles Polyethylene Helixes Variable Pitch Helix Additional Options for mixing, stirring, spreading, and pulse elimination, and for handling difficult materials with special properties eg sticky, stringy, lumpy, aerated, cohesive, abrasive, dusty or fragile. Specialised systems are also possible which do not use screws, such as vibratory feeders, rotary valve feeders, belt feeders and others.
