The benefits of going gravimetric

A gravimetric feeder, being a belt feeder device, weighing the coal actually passing over the belt, will react to any reduced feed out of the bunker. The feeders must preserve the entire downward force of coal from the bunker and redirect it in the direction of flow. A belt feeder does this better than a drag chain feeder and gives a more ...

Smart Refill Technology in Loss-in-Weight Feeding

overall feeder size and cost by enabling refill to occur at a much higher frequency than before. In earlier loss-in-weight systems a low frequency refill approach was taken as pictured in Figure 4. In that approach a relatively lengthy gravimetric feeding phase is followed by refill whose duration should not exceed 10% of the gravimetric phase.

Improve the Performance Of Your Gravimetric Feeder

In answering, the first thing you need to tell us is the material you are feeding. Gravimetric feeder performance is most always affected by how well the material feeds volumetrically. The closer you can fill the flights of the feed screw volumetrically to , the better the feeder will perform gravimetrically.
