Abstract
Open, circulating air conveyor for granular material. The arrangement comprises an open feed silo 1, from which a feed screw dispenses the granular material 3 to the intake opening 5 of a conveyor fan 4. The conveyor fan carrier air consists of circulating air, the quantity of which is maintained by a circulating air intake unit 10 by means of a frequency converter 11 and a pressure sensor 12, so that no air flow occurs in either direction in the outlet opening 2 of the feed silo 1. <IMAGE>
