ABSTRACT:
Compressed air is introduced into a feed pipe system for transporting powdery or granular material in order to promote dense flow conditions. Variable or fixed size restrictions with decreasing size of blocking surface in the direction of the material flow equalize the amount of air entering the feed pipe along its entire length. The compressed air is introduced into the feed pipe through porous materials positioned at least in the region of the restrictions.
