Practice of Overhaul Technical Reform of Concentrate Drying System of Jinchuan Nickel Flash Smelting

The paper focuses on the technical reform work done by the Jinchuan nickel flash smelting concentrate drying system in the overhaul in 2010. Through nearly one year of operation, the system process control has achieved optimal adjustment, and the problems exposed before the overhaul have been effectively solved. It realizes high-load production and lays a solid foundation for continuous, safe, efficient and stable operation of the flash furnace. At the same time, some non-standard designs used in some equipments and facilities during overhaul have proved that the operation is in good condition and can be used for reference in the same industry.
