Loss In Weight Feeder Principle

Loss-in-Weight Overview : Plastics Technology

2 d. geleden  Material Containment - Loss-in-weight feeders readily lend themselves to complete material containment where dusting or safety/toxicity concerns apply. Tare – Under the loss-in-weight principle, moment-to-moment differences in weight matter, not absolute weight. Thus, for the purpose of feed rate control, tare becomes irrelevant.

How to Design a Loss-in-Weight Feeder

A gravimetric loss-in-weight feeder simply weighs material to achieve a required feed rate or batch size. Depending on the feeder type, a loss-in-weight feeder can operate in continuous or batch mode. The continuous feeder controls the weight (not volume) of material fed over time -- typically in lb or kg of material per hour.
