Abstract

Many industrial processes involve the discharge of powders or granular material. Examples of this include the filling of road/rail wagons at the larger end of the scale of activity, and filling of big bags or sacks on a smaller scale. For the majority of these applications it is desirable to achieve a degree of consistency and repeatability in what flow stream property of successive discharges for the in flight material in order to facilitate process control and accuracy of filling. Most processes utilise a combination of aeration and/or large outlet sizes to obtain high instantaneous discharge rates - often to the detriment of accuracy or control. This paper will consider the fundamentals of a previously unreported discharge behaviour that is specifically linked to the gravity discharge of plane-flow (wedge) type vessels when interfaced to a secondary plane-flow geometry.
