  • Difference Between Gravimetric and Volumetric Feeder ...

    Jun 19, 2018· The 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. There are two forms of feeders and we call them as gravimetric feeders and volumetric feeders.

  • Gravimetric and Volumetric Coal Feed Systems for Boilers

    Schenck Process LLC Gravimetric Feeders monitor the weight of the coal and raise or lower the belt speed to instantaneously compensate for these changes in density. This improvement in the feed rate consistency, and thus the actual weight of fuel delivery, allows a closer matching of fuel to air to minimize unburned carbon losses and stack losses.
