This system accepts an external command from process computers like SCADA, HMI, DCS etc. This type of weigh feeder used in industries like Steel Plant, Cement Plant, Fertilizer and Chemical industries
The Advantages, Limitations and Considerations of Weigh Meter Overview. Principle Mostly encountered in primary resin compounding where throughputs are high, the combination of rotary valve and a gravimetric solids flow meter offers a simplified alternative to the use of a weigh-belt feeder in controlling base resin (fluff) feed rate for the proportioning of additives prior to
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)

A loss-in-weight feeder is a gravimetric feeder that directly measures the material's weight to achieve and maintain a predetermined feed rate measured in units of weight per time. The following section ( The Gravimetric Feeding Triangle ) introduces the three main challenges faced by any gravimetric feeder: material handling, weighing and control.
Gravimetric Feeder Principle The gravimetric feeder weighs material on a length of belt between two fixed rollers using a weighing roller suspend-ed from load cells. Belt speed is determined by a tachometer attached to the motor shaft. microprocessor multiplies the speed and weight signal to arrive at the feeder output material flow rate.
ii. Feeder The feeder controls and meters the flow of bulk material from the hopper to meet the specified discharge flow rate. The importance of the hopper and feeder to be designed as an integral unit cannot be too greatly emphasised. A well designed hopper may be prevented from functioning correctly if the feeder is
Rotary feeders, also known as rotary airlocks or rotary valves, are commonly used in industrial and agricultural applications as a component in a bulk or specialty material handling system.Rotary feeders are primarily used for discharge of bulk solid material from hoppers/bins, receivers, and cyclones into a pressure or vacuum-driven pneumatic conveying system.
