Embodiment

[0026] 2. see figure 1 , the proportion of pellets in the sintering mixture is 40%, the mixture is distributed from the distributor 1 to the sintering machine trolley 3, and the distribution regulator 2 is used. The angle between the distribution regulator 2 and the vertical direction is 30 degrees, the width of cloth adjuster 2 is the same as that of the inside of sintering machine trolley 3, the height is 300mm, and the thickness is 10mm. The distance between cloth adjuster 2 and the bottom of cloth distributor 1 in the horizontal direction is 300mm. The specific distance depends on the height of the sintering material layer and the feeding speed Adjustment; the lower end of the cloth adjuster 2 is 280mm away from the bottom of the sintering machine trolley 3, and it is adjusted according to the thickness of the sintered material layer on the sintering machine trolley 3. The contents of pellets in the upper, middle and lower layers of the material layer accounted for 31%, 21...

Abstract

This invention discloses a material distributing method of iron fine ore composite agglomeration. A material distributing adjuster is mounted in the front of a discharge port of a material distributer and on a sintering machine. Mixed materials are transported by the material distributer. When the mixed materials are moved the bottom end of the material distributer and the sintering machine, a material column is formed between the material distributer and the material distributing adjuster. The front, rear, upper and lower positions, and the horizontal angle of the material distributing adjuster are adjusted. The moving speed of a pellet and the distribution thereof in the material layer are controlled so as to realize the reasonable distribution of the pellet in the mixed material. In the producing process, the material column is formed between the material distributer and the material distributing adjuster. The front, rear, upper and lower positions, and the horizontal angle of the material distributing adjuster are adjusted. The moving speed of a pellet and the distribution thereof in the material layer are controlled so as to realize the reasonable distribution of the pellet in the mixed material.

Description

technical field [0001] The invention relates to a method for distributing sintered mixture on a belt-type sintering machine, in particular to a method for distributing the mixture suitable for the composite agglomeration process of iron ore powder. Background technique [0002] The iron ore powder composite agglomeration process (ZL 200510032095.6) is to separately separate part or all of the fine-grained iron ore powder suitable for pelletizing to prepare pellets, and the rest of the iron-containing raw materials are mixed with fuel, flux and returned ore. The pellets are prepared into a primary mixture, the pellets are mixed with the primary mixture to prepare a final mixture, and then spread on a belt sintering machine for sintering and roasting to form a composite smelter composed of acidic pellets embedded in high-basic sintered ore. Iron charge. The new process can make full and reasonable use of iron ore resources, improve the air permeability of the sintering materi...
