The discharge rate from a storage vessel is typically controlled by a feeder, such as a screw feeder or belt feeder. When entrained in air, a fine powder can sometimes behave like a fluid. Since feeders are usually designed to handle solids rather than fluids, discharge may become uncontrollable; in extreme cases, the hopper may empty ...

Bin Design and Construction

Belt Feeders. The slot-type belt feeder is one of the most economical feeders for bulk solids. Although this type of feeder has been in use for about 50 years, it only has recently found industrial acceptance. Properly applied, the belt feeder lends itself nicely to low first cost, dependable operation and automatic control.

How feeder design impacts silo discharge

Reliable bulk solids material flow from a bin or silo requires that the silo hopper is designed to create the correct flow pattern (funnel flow or mass flow) during discharge. In funnel flow, material above the hopper outlet moves during discharge while material along the hopper walls remains stationary or stagnant (Figure 1, left).

Bulk solids handling & Engineering

The load which is exerted on a feeder can vary, and is largely affected by the initial bin fill condition, feeder type, and the draw down effect of the resultant hopper flow pattern. The following Figure 1 shows a typical representation of feeder loads comparing initial bin fill conditions flow conditions. Belt feeder and belt conveyor design

Discharge of Bulk Solids

The unrestricted rate of discharge of a bulk solid under gravity (i.e., when an outlet is opened) is dependent on several parameters, e.g., the bulk solid's properties, the size and shape of the outlet, the hopper inclination, and, in the case of funnel flow, the shape of the stagnant zones [1, 2].The conditions of unrestricted discharge can also be fulfilled in the …
