Selecting a gravimetric feeder: Weighbelt or loss-in-weight
To select a gravimetric feeder for your application, you need to consider the feeder's design and operation in terms of your process requirements. This article describes two common types of gravimetric feeders -- weighbelt and loss-in-weight -- and lists several selection factors to help you choose the right feeder.
The term feeder describes a mechanical device that moves material from one point to another at some required rate. The device can feed by volume [called a volumetric feeder] or by weight [called a gravimetric feeder].
