Many different models have been postulated over the years for sizing of feeder drives; these models
have different bases, some rationally based and others more rule-of-thumb. Experience of Jenike &
Johanson and likewise of The Wolfson Centre in trouble-shooting feeder drives has shown that
drive powers are often poorly matched, so there is clearly still some way to go towards establishing
a universally-used reliable approach.
This paper presents an on-going programme of work designed to measure feeder forces experimentally on a purpose designed testing rig, and to compare these against some of the best known available models, and also against a full size installation.
One aspect which is novel is the monitoring of the transition between the “filling stress field” load
on the feeder and the “flowing stress field” load
