Matching Feeder Extraction Pattern with Hopper | Bulk-Blog

A similar handicap applies to screw feeders in that the initial section of screw exposed to the hopper contents will extract the full axial transfer capacity, whereas subsequent flights can only take out the marginal increase in capacity. Further, a common attempt to secure incremental extraction is to increase the pitch of the screw along to axis.
