A loss in weight feeder is a gravimetric metering device that receives material from an upstream supply and accurately doses the material into a process at a predetermined feedrate, typically through a screw (helix), or vibratory tray.
Rate by weight is the measurement of an amount of a material which enters into or is dispensed from a vessel over a given period of time. Solids, liquids or gases can be monitored or precisely controlled using screw- or auger-based feeders, vibratory feeders, conveyors, belt feeders, variable valves and pumps.
Loss-In-Weight Feeder The continuous loss-in-weight principle involves weighing the entire feeding system (hopper, feeder, and bulk material) by means of a static-type scale system, and controlling the discharge feed rate of the bulk material by means of a variable speed motor. Material is discharged from the system, via screw or vibratory tube ...

The LWF-15L-V "Spiralator" Loss-In-Weight Vibratory Feeder is designed to operate over a very wide operating range (typically 100:1), while assuring uniform, non-pulsating flow of difficult-to-discharge materials, whether they be fine cohesive powders or fragile interlocking particles of irregular shape.
A loss in weight feeder is a gravimetric metering device that receives material from an upstream supply and accurately doses the material into a process at a predetermined feedrate, typically through a screw (auger or helix), twin screw, or vibratory tray.
A loss-in-weight feeder is the state of the art today for providing gravimetric (weighing) feeding of a bulk solid. In previous articles I discussed volumetric feeding, which relies on a certain volume/unit time (cu ft/hr or cu m/hr) to maintain feed rate accuracy.
Vibratory Tube Feeders Similar to vibratory tray feeders, vibratory tube feeders can utilize electromagnetic or brute force (offset weight vibrators) and feed dry materials in an enclosed tube to downstream equipment.
