What is a Weigh Feeder ? Instrumentation Tools

The load cell measures the weight of a fixed-length belt section, yielding a figure of material weight per linear distance on the belt. A tachometer (speed sensor) measures the speed of the belt. The product of these two variables is the mass flow rate of solid material “through” the weigh feeder: Where, W = Mass flow rate (e.g. pounds per second)

Loss-in-weight feeders Schenck Process

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.

How to Design a Loss-in-Weight Feeder powderbulksolids

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.
