Volumetric Feeder - Schenck Process

Volumetric Feeder Volumetric feeders supply a certain volume of material per unit of time. Known volume units of a particular material are used for the volumetric measurement and the material is transferred to a mass-based discharge using scanned calibration. Feeding is changed by adapting the auger speed.
