Gravimetric Feeders Are Inherently More Accurate than Volumetric. The MGF feeder uses load cells to accurately monitor the loss in weight of colorant in the hopper as the material is fed into the injection molding machine or extruder by an auger. The only system component actually mounted on .
Pressurized Gravimetric Feeders. The STOCK gravimetric coal feeder weighs material on a length of belt between two fixed rollers (span) precisely located in the feeder body. A third roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span.
Gravimetric Feeders The feeder was typically located immediately beneath the coal bunker and immediately over one of the pulverizers. Coal would pass down into the feeder and onto the horizontal transfer belt within the feeder body. As the coal proceeded from the .
