            Volumetric dosing with ProTec systems

            Functional principle

            In volumetric dosing, material is discharged solely on a volume basis by adjusting the speed of the dosing element, the bulk material present in a material storage bin being supplied to the process. The volume of material to be metered, after calibration to the material's particular bulk density, is adjusted via the speed of the dosing screw or the number of dosing chambers.

            If there are changes in individual product properties, such as bulk density or grain size, the product characteristic must be redetermined and adjusted (calibration), since such changes cannot be automatically compensated. Advantages of volumetric systems include excellent dosing accuracy subject to careful calibration, compactness and low price.
