2.3 Penetration characteristic test. In addition to the MF of iron ore fines, the penetration characteristics of CIC melt into other iron ore nuclei were investigated as the basis of ore-blending optimization for CIC. 3.5 g of + 0.5 mm particles of OA–OD was crushed into − 0.074 mm fines and then shaped under a pressure of 30 MPa into a …
In addition, the influence of ore blending on ore dressing is reported in some of the research [10, 12, 14,32]. It is difficult to treat the ore blending target as a constraint to meet the ...
Blending is the process of combining two or more materials to achieve a combined product. The mixture may be a combination of dissimilar materials such as cement, sand and aggregate to make concrete; or cereal flakes, raisins, nuts and marshmallows to make breakfast cereal. A blend may also be a combination of …

The physical and chemical properties of iron ore fines under high temperature directly affect its sintering performance. ... The negative pressure on the bottom side of materials bed will leading larger amount of gas ...
According to the complementary principle of the basic properties between iron ores, the blending model takes the minimum blending cost as optimization objective, …
For production cost reduction, optimised blending ratios were designed according to ore prices and properties (microstructure, crystal water decomposition, assimilation ability, liquid phase fluidity), ensuring nearly identical chemical composition as the mixture used in actual sintering. Sinter pot tests were conducted to determine the …

An ore-blending optimization model for the sintering process is an intelligent system that includes iron ore characteristics, expert knowledge and material balance. In the present work, 14 indices ...
In previous studies, ore-blending schemes in the sintering process were usually proposed based on the technicians' experience. The actual production would easily run into dif-ficulty when the raw materials were changed, in particular, when new kinds of iron ores were introduced [1-3]. As a result, the ore-blending model based on chemical composi-
Blending here would provide a uniform mineral content which would aid in fine tuning the extraction process to attain maximum output. 2) The presence of an undesirable type of ore that could be processed but which would cause a reduction in overall output if it comprised too large a percentage of the mill feed.
An ore-blending optimization model for the sintering process is an intelligent system that includes iron ore characteristics, expert knowledge and material balance. In the present work, 14 indices are proposed to represent chemical composition, granulating properties and high temperature properties of iron ores. After the …

It is an important means to solve this problem to seek the particle size matching between solid fuel and iron ore fines. The suitable matching mode of fuel particle size (d) and blending ore particle size (D) is as follows: d/D = 0.47 ~ 0.54. When the particle size of blending ore changes, the fuel particle size should be controlled …
