RING SIZE EFFECT ON THE REDUCTION OF PULS ATING WALL-PRESSURE NEAR THE TRANSITION IN A BIN

This paper outlines an approach to reduce the pulsating wall pressure near the transition point in a bin which is generated during discharge of a dense bed achieved by peripheral feeding. The author presents a method of controlling the flow of the dense bed by means of a ring ins talled in the wall near the bin transition point, thus changing the fl ow from a dense bed to a coarse bed.
