FIELD: metallurgy.

SUBSTANCE: device to produce granulated metallic iron by placing a mixture of raw products containing iron oxide and carbonaceous reducing material, on the sole of a heating furnace of movable sole furnace type and by heating of the charge to reduce iron oxide in the charge to obtain granulated metallic iron. The device also comprises a sieving unit, the first magnetic separator and the second magnetic separator, a channel through which the material unloaded from the heating furnace of movable sole furnace type is delivered to the sieving unit, a channel through which large granules that were sorted out in the sieving unit are delivered to the first magnetic separator, and a channel through which fine granules that were screened in the sieving unit are delivered to the second magnetic separator.

EFFECT: higher efficiency of the device.
