Abstract
Natural segregation of particles often needs to be controlled directing the bulk solids into downstream processes. Such control is especially a requirement when the downstream flow is to be split into separate streams and/or evenly spread across processing equipment.
This paper reports on a model study where segregation was controlled by employing a square standpipe with a helical twist down the axis of the standpipe. A summary of the outcomes is provided where it was shown that it is possible to control the flow of a bulk solid down a vertical choked flow standpipe by inducing a helical twist in the standpipe and hence providing a positive influence on the downstream segregation issues.
