Because the pitch varies through the inlet, it makes reversing the screw feeder to feed the other direction an impossible task without compacting the bulk material and plugging the screw flights. Reversible screw feeders with central inlets must have a control valve above the inlet to ensure bulk material flow is completely stopped.
