(PDF) DESIGN AND APPLICATION OF FEEDERS FOR THE

Consider, for example, a conical hopper handling coal with δ = 45°. If the hopper is of mild steel it is subject to corrosion, the angle ø is likely to be approximately 30°. On this basis, from Figure 3, the limiting value of α, = 13°. A margin of 3° is normally allowed making α = 10° which is a very steep hopper.

Coal from each of the hoppers is extracted by means of individual variable speed belt feeders. These frequency-controlled feeders extract coal from the hoppers and transfer it to the longitudinal conveyor. The belt width of the feeders is kept high and the speed is low to ensure uniform extraction of coal from the hoppers.
