Problems solved by technology

However, due to the relatively poor water affinity of the sintered fine powder, it is difficult to disperse the water evenly in the traditional sintering process, and the uniform dispersion of water is very critical for the granulation effect, and the sintering of the fine powder affects the air permeability due to its hindrance. Production efficiency of sintering machine
In the existing process, as the raw material of iron ore powder for sintering, due to the poor mixing of fine powder and coarse particle ore, less fine powder ore and more coarse particle ore are mixed, and the addition amount of fine powder is generally Between 20-30wt%, the highest can only reach 40wt%

Abstract

The invention provides a mixing method for sintering production. The mixing method comprises the following steps that 1, iron ore powder, solvent and fuel are conveyed into a strong mixing machine, water is added, and mixing of the first stage is carried out; 2, the material obtained after mixing of the first stage is conveyed into a first cylinder mixing machine, water is added, and mixing of the second stage is carried out; 3, the material obtained after mixing of the second stage is conveyed into a second cylinder mixing machine or a cylinder pelletizer, water is added, mixing of the third stage is carried out, and a mixed material is obtained. By the adoption of the vertical strong mixing machine, the occupied area can be reduced, moreover, the sintering strength of sintered ore can be improved, the yield of the sintered ore is increased, energy is saved, emission is reduced, and multiple advantages are brought to increase of profits of sintering factories.

Description

technical field [0001] The invention relates to a method for preparing iron ore pellets for sintering (that is, a mixture for sintering) and a device thereof, belonging to the technical field of sintering technology in sintering plants, and in particular to a powerful mixing process and a mixing device for sintering production. Background technique [0002] At present, the iron-containing materials used in large and medium-sized blast furnace ironmaking production are mainly massive iron ores (sintered ore, pellet ore and rich lump ore) with a grade higher than 55%. Sintering ore is the man-made rich ore with a certain particle size by mixing fine ore, concentrate, secondary iron-containing dust, limestone, dolomite and other fluxes and fuels that cannot be directly added to blast furnace smelting, and then sintering in a sintering machine. From the perspective of iron ore resources around the world, the proportion of fine iron concentrate and ultrafine iron concentrate cons...
