Jun 19, 2018· A gravimetric feeder consists of a volumetric feeder associated with a weighing system. It measures and controls the discharge of a substance at a constant weight per unit time. A volumetric feeder, on the other hand, is a screw conveyor that runs at a constant speed, discharging the substance at a constant volume per unit time.

Gravimetric feeders should be used whenever there is a requirement for close control of material discharge. Examples include when the feed rate uniformity must be better than ±2%, or sample collection times must be less than about 30 sec. A gravimetric feeder should also be used when the bulk density of the material varies. Criteria for Feeder Selection

Generally, the gravimetric feeder receives the particulate coal in the form of a continuous stream in a fixed flow path, and delivers the coal at a controlled rate as freefalling or separately flowing particles. The rate of discharge by weight is controllable to achieve accurate control of the fuelair ratio.

"Because a gravimetric system generates a wealth of data on color consumption, it adjusts color metering far more accurately to account for process variations." The key to adjusting for process variations is Maguire's LossinWeight software in the feeder control.
