Estimating tons of coal on a property , Kentucky ...

Sep 19, 2019· The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal, is to

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.

Should coalfired power plants use gravimetric feeders?

In light of this reality, gravimetric weigh feeders are the better option. These instruments calculate a substance's total weight, using that value to determine how much coal to feed. Substituting a gravimetric feeder with a volumetric equivalent isn't feasible for power plants.
