How to Design Efficient and Reliable Feeders for Bulk Solids

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 other hand,

To determine the shortest and optimal feeder possible requires flexibility in the layout of positioning the apron feeder under the hopper (L2). After determining the shear length and bed depth, the overall length can then be minimised just enough to prevent what is referred to as “self-flushing” over the discharge end when the feeder is idle.
