When selecting a feeder, how can I determine whether
Volumetric feeder types include screw (helix), rotary vane, belt, vibratory, en masse, and table feeders. The term open-loop feederapplies only to a volumetric feeder since there’s no feedback information between the feeder output and the drive control system. In contrast, a gravimetric feeder feeds material by weight and provides closed-loop

Coal Feeder Volumetric To Gravimetric Conversion
For all Makes & Models of Coal Feeders * Improve plant heat rate * Account for fuel use Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand system, but the actual amount fed is estimated and the accuracy can vary greatly.
