METHOD FOR PROCESSING MATERIAL IN THE FORM OF PARTICLES AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2006 - IPC C22B1/10 C21B13/00 C22B5/14

Abstract RU 2289633 C2

FIELD: processing procedures, mainly reducing material in the form of particles at least in one fluidized bed zone at elevated temperature, for example reduction of finely disintegrated ore.

SUBSTANCE: material in the form of particles is held in fluidized zone by means of flow of processing gas passing from below to upwards. Fine-grain material passing from fluidized zone by action of processing gas is separated from processing gas in separation zone. In said zone next operations are realized: flow of processing gas and fine-grain material are fed to separation apparatus; fine-grain material is separated from processing gas due to removing processing gas out of separation apparatus as exhaust gas. Then fine-grain material is removed from separation apparatus and large-grain material is supplied to separation zone.

EFFECT: lowered agglomeration degree, reduced quantity of deposits.
