Abstract
Powdery material flows downwardly along a vibratory spiral conveyor chute, while gas flows counter to the powder, preferably in excess. Mixing ramp arrangements are provided in the chute. These involve inclined ramp surfaces dividing the powder stream into two layers, and provisions for causing the initially uppermost layer to tumble down onto the chute bottom while the initially lowermost layer is still supported on its ramp. The latter then drops down, too, and now becomes the uppermost layer.
