A reliable volumetric device is essential for a high accuracy gravi-metric weigh feeder. The feed rate is measured by volume against time. The feedrate or batch weight is regu-lated by the process controller. Volumetric feeding Gravimetric Feeding Batch feeding Continuous feeding Combination feeding Using a gravimetric feeder with
Gravimetric or loss-in-weight: A feeder usually identical in design to a volumetric feeder but mounted to a weigh platform to measure the weight lost from the feeder over intervals of time. The main benefit is that any changes in bulk density are detected and allow the screw speed to be varied to maintain the set rate.
sary to turn to gravimetric feeders. Probably not over a dozen installations of gravimetric feeders were to be found in the United States prior to 1935 when the Omega Machine Co. began promoting their sale, but then development came quickly, International, Jeffrey and Syntron following with designs of the same character.
A 0.5% variation in the additive level may make the product unacceptable. Using volumetric feeders to add flame retardant additives may produce the wrong ratio and make the product have a UL94 V-1 flammability rating instead of V-0. One alternative is to add free flowing pellets with a volumetric feeder and other additives with gravimetric feeders.
Volumetric feeding falls short of capacity requirements when a material has a varying bulk density. Material that can vary widely in bulk density within a batch will struggle to meet dosing requirements with a Volumetric feeder. Choosing the right feeder for your application is important to the …

A true volumetric feeder encompasses a positive method of measuring a specific volume of product and a means to effectively discharge that material, generally over a variable range. With an auger type volumetric feeder, the auger is the means used to measure volume, discharging the measured volume of material with each revolution, as it rotates ...
Gravimetric or loss-in-weight feeders are more sophisticated than volumetric feeders. [9] The same general feeders used to feed materials volumetrically (single screw, twin screw, vibratory, and belt) are converted to gravimetric feeders by placing the feeder on a scale.
