Zusammenfassung:	A supply system for providing a suspension smelting furnace with constant and continuous feed is disclosed. The installation of the invention comprises intermediate storage bins for fine-grained feed, a feed rate controller for accurately controlling the feed rate of the fine-grained material, and a pneumatic conveyor for lifting the feed up to the top level of the suspension smelting furnace where the burner of the furnace is adapted. In the installation, the heavy constructions of the storage bins are located close to the ground level and the constructions around and on top of the furnace have been designed essentially lighter than in conventional solutions. L'invention concerne un système d'alimentation pour un four de fusion de suspension, assurant une alimentation constante et continue. L'installation décrite comprend des trémies intermédiaires pour une charge à particules fines, un régulateur de débit permettant de réguler avec précision le débit d'alimentation en particules fines, et un transporteur pneumatique permettant d'élever la charge jusqu'au niveau supérieur du four de fusion de suspension, où est installé le brûleur. Dans l'installation décrite, les structures lourdes des trémies sont placées à proximité du niveau inférieur, et les structures disposées autour et dans la partie supérieure du four sont construite sur un modèle plus léger que dans les solutions conventionnelles.
