CONVEYER ROASTING MACHINE FOR HEAT TREATMENT OF PELLETS Russian patent published in 2001 - IPC

Abstract RU 2173824 C1

FIELD: ferrous metallurgy; preparation of raw materials for blast-furnace process. SUBSTANCE: conveyer roasting machine is provided with unit for two-layer loading of pellets which consists of roller feeder, lower layer drying chamber and blast-and-draft devices. Unit for two-layer loading of pellets is provided with roller classifier and bow-shaped conveyer located after roller feeder above lower-layer drying chamber embracing in on either side. EFFECT: simplified construction; reduced power requirements due to separated fraction-by-fraction loading of pellets and separate drying of pellets. 1 dwg
