<p>This invention relates to a process and system for treating ultra fine powder steel slag, which comprises: collecting the steel slag into a tank and carrying the tank onto a tipping device by a hoisting equipment; operating the tipping device to transport the steel slag to a granulating device and granulating the steel slag in the granulating device to form granulated slag; transporting the granulated slag into a drying room with a conveyor, wherein the granulated slag is continuously dried in the drying room at a temperature between 200 - 300°C for 30-60 seconds using exhaust heat from a converter; and transporting dried granulated slag, with the conveyor, to a magnetic separation device to separate carbon metal grains from nonmetal grains contained in the granulated slag.</p> |
