    • How to Design Efficient and Reliable Feeders for Bulk …

      2019-3-20 · There are two basic types of feeders used in industrial plants: volumetric and gravimetric. As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (e.g., cu. ft./hr.). The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan. A gravimetric feeder, on the ...

    • Weight-sensor calibration for gravimetric coal feeder ...

      Generally, the gravimetric feeder receives the particulate coal in the form of a continuous stream in a fixed flow path, and delivers the coal at a controlled rate as free-falling or separately flowing particles. The rate of discharge by weight is controllable to achieve accurate control of the fuel-air ratio.

    • Difference gravimetric and volumetric feeder | Movacolor

      A gravimetric feeder, also know as a loss-in-weight feeder, is a self-calibrating dosing system that doses based on weight in speed. A volumetric feeder, on the other hand, does this based on volume in speed. In gravimetric dosing, the weight of the dosed additive is measured using a load cell that is the foundation of the entire system.
