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. True to its “loss in weight” name, this feeder’s operation is regulated by the amount of live load that is lost as product is discharged. In order to do this effectively, the loss in weight feeder receives constant feedback from a sensitive weighing device, which ensures that the precise amount of material is delivered either continuously or in each batch. |
