The weigh belt feeder is under gravimetric control for nearly the whole working cycle since the weighted portion of the device does not need to replenish, unlike a loss-in-weight feeder. Compared to the corresponding loss-in-weight feeder, the machine has a smaller footprint and less headroom for feeders with large throughputs.
