Abstract

See full text

A suspension roasting system includes a feeding bin, a Venturi dryer, a first cyclone preheater, a second cyclone preheater, a pre-oxidation suspension roasting furnace, a thermal separation cyclone cylinder, a suspension and reduction roasting furnace, a collecting bin, a grinding machine, a magnetic ore separator and a draught fan. A suspension roasting method includes: crushing iron and manganese ores; conveying the ores to the Venturi dryer; starting the draught fan and enabling combustion gas in the Venturi dryer to be mixed with dust ores to remove water; enabling obtained solid materials to enter the pre-oxidation suspension roasting furnace after being preheated by the first and second cyclone preheaters; enabling obtained gas to enter the suspension and reduction roasting furnace through the thermal separation cyclone cylinder; performing suspension and reduction roasting; enabling obtained reducing slag powder to enter the collecting bin through cooling cyclone cylinders; and performing grinding and magnetic separation.
