In the case of conical hoppers the limits for mass-flow are clearly defined and quite severe while the plane-flow or wedge-shaped hoppers are much less severe. 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°.

hopper shown in Figure4, has an elongated material outlet, the outlet width can be half that of a cone-shaped hopper without causing material bridging. When using a plane-flow hopper, however, you must ensure that the feeder below the hopper is designed to effectively work with the elongated hopper outlet (discussed below). Expanded-flow hopper.

How to Design Efficient and Reliable Feeders for Bulk Solids by John W. Carson, Ph.D. and Greg Petro, P.E. A feeder is an extremely important element in a bulk material handling system, since it is the means by which the rate of solids flow from a bin or hopper is controlled. When a feeder stops, solids flow should cease. When a

Material handling may be divided into classifications or actions related to the stage of the process. For some materials the first stage is its existence in its natural state in nature, e.g., in the earth or ocean. In other cases the first stage would be its receipt at the factory's receiving dock. Subsequent material handling actions ...
hoppers with "hammer rash" due to operators reverting to the basic method of hammering. Overall, it is very disappointing to those that promote excellence in bulk solids handling system design, to see that the up-take of the rational method for hopper design has been so
