Abstract
This paper outlines an approach to reducing the pulsating wall pressure near the transition point in a bin which is generated during the discharge of a dense bed achieved by peripheral feeding. The authors present a method for controlling the flow of the dense bed by means of installing a device that widens the cylindrical section near the bin transition point, thus changing the flow from a dense bed to a loose bed state. The stress states in the hopper section before and during discharge are explained by Mohr circles.
In particular, this method can reduce the pulsating wall pressure in the hopper that maintains the dense bed in the cylindrical section of the bin.
