| titleOfInvention | A kind of system and method for rotary hearth furnace processing troilite |
| abstract | The present invention discloses a kind of system and method for rotary hearth furnace processing troilite.The system includes rotary hearth furnace and mill ore magnetic selection equipment, rotary hearth furnace includes feeding mouth, discharging opening, reducing agent entrance, exhanst gas outlet and barricade, barricade is located in the body of heater of rotary hearth furnace, annular space in body of heater is divided into oxidizing roasting area and reduction roasting area, barricade includes hollow barricade and solid barricade, reducing agent entrance is provided with the top of hollow barricade, up/down perforation inside hollow barricade, rotary hearth furnace feeding mouth is located at oxidizing roasting area, rotary hearth furnace discharging opening is located at reduction roasting area, and exhanst gas outlet is located at oxidizing roasting area.System and method provided by the invention, realize troilite oxidizing roasting and integrally completed with reduction roasting；The desulfurization oxidation of oxidizing roasting area is abundant, and reducing agent is uniformly layered on by hollow barricade above the pelletizing after desulfurization aoxidizes, and is avoided flying upward in reducing agent high position dropping process and is burnt；Flue gas caused by collection is used to prepare sulfuric acid；The Iron concentrate grade that mill ore magnetic selection obtains is high. |
