Technical Field

[0001] The utility model belongs to the technical field of feeding systems, and in particular relates to a nickel side-blowing smelting furnace configuration and feeding system. Background Art

[0002] The nickel side-blowing smelting mixing and feeding system mainly provides production materials for the side-blowing furnace. The material ratio needs to be adjusted in time according to the production situation of the side-blowing furnace. The copper-nickel mixed concentrate is mixed with the purchased concentrate in proportion. The mixed concentrate is transported by belts and mixed with flux and lump coal in a certain proportion and then added to the side-blowing smelting furnace through belt conveyors. The nickel side-blowing smelting furnace mainly uses high-magnesium low-refined and nickel-containing tailings as production raw materials. Due to the complexity of processing raw materials, the auxiliary materials such as lump coal and quartz that need to be added are relatively strict. In order to better make the furnace reaction, the auxiliary materials are added separately. Therefore, the material mixing of the mixing and feeding system is relatively complicated. In the past, the mixing and feeding process required the selection of the required types of raw materials manually, and they were manually grabbed into the silo, which had the problem of low efficiency.
