Difference Between Gravimetric and Volumetric Feeder

19/06/2018· 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.

Should coal fired power plants use gravimetric feeders?

Substituting a gravimetric feeder with a volumetric equivalent isn't feasible for power plants. Machinery that burns coal to produce a specific amount of energy must not receive an excess or paucity of material. If a pulveriser, for example, receives more coal than it is equipped to handle, the mechanism may break, resulting in downtime and lost productivity.
