    Difference Between Gravimetric and Volumetric Feeder . Jun 19, 2018The key difference between gravimetric and volumetric feeder is that we measure the rate of a gravimetric feeder in the unit of volume per unit time whereas we measure the rate of a volumetric feeder in the unit of weight per unit time.. Feeders are useful to handle bulk solids.

    Difference gravimetric and volumetric feeder | Movacolor

    A volumetric feeder is a dosing system that supplies the production system with a certain volume of material in a set timeframe, based on the socalled displacement principle. In contrast to a gravimetric feeder, the dosing speed of a volumetric feeder should be selected manually, which may vary based on the nature of the raw input materials.

    Basic Screw Feeder Design. It is not recommended to design screw feeders with uniform outside diameter and constant pitch because bulk materials will fill the screw from the rear of the inlet opening first, creating ratholing, stagnant material and possible bridging of bulk materials above the screw feeder.

    The feeder is designed to vary the frequency of the system to the resonance point while maintaining the amplitude frequency at the desired set point. Figure shows two slightly different volumetric vibratory feeders. Similar to volumetric screw feeders, the feed rate depends on a constant vibration frequency and free flowing feed material.
