Loss in Weight Feeding Weighing systems, vacuum. The Rospen loss-in-weight feed system has been designed to weigh and control the output of variable products continuously to weight accuracies of ±0.25% to ±1%. The general principle of operation is as follows:- • The loss-in-weight hopper is rapidly filled via an automatic filling valve.
04-08-2021· Loss-in-Weight Overview. Principle. In loss-in-weight feeding, the entire feeder, hopper and material are continuously weighed. As the feeder discharges material, the rate of decline in system weight is computed, and feeder speed is adjusted to maintain the desired (set) rate. Advantages, Limitations and Considerations.
Principle: When the material is fed through the feeder, the weight of the system decreases. Controlling the loss-in-weight feeder changes the feed rate and as a result the speed of weight loss matches the desired feed rate. Loss-in-weight feeder controls continuously check whether the material is flowing.
