Novel binding agent as well as preparation method and application thereof

Abstract

The invention provides a novel binding agent. The novel binding agent is prepared from the following raw materials: 20 weight percent to 70 weight percent of dust-removal ash of a titanium slag electric furnace, 20 weight percent to 70 weight percent of a plant adhesive and 1 weight percent to 10 weight percent of polyacrylamide. The invention further provides an agglomeration method of powder resources; the agglomeration method comprises the following steps: a) carrying out dry mixing on the powder resources and a binding agent; then adding water to carry out wet drying, so as to obtain a mixture, wherein the binding agent is the novel binding agent provided by the technical scheme or the novel binding agent prepared by a preparation method provided by the invention; b) granulating and molding the mixture obtained by step a) to obtain a molded agglomerated block. Compared with the prior art, the novel binding agent provided by the invention takes the dust-removal ash of the titanium slag electric furnace as a main raw material and the main raw material is matched with other components with specific content; the novel binding agent has relatively high resource utilization rate andrelatively low cost; meanwhile, the novel binding agent is applicable to granulation and molding of the powder resources and has relatively high molding rate and strength, so that the powder resourcesare sufficiently utilized.

Description

technical field [0001] The invention relates to the technical field of granulation and molding, and more specifically relates to a novel binder and its preparation method and application. Background technique [0002] Electric furnace smelting titanium concentrate to produce high-titanium slag is the main method for processing titanium raw materials. Panzhihua Iron and Steel Co., Ltd. has three titanium slag electric furnaces, which can process 250,000 tons of titanium concentrate and produce 140,000 tons of high-titanium slag annually. [0003] In actual production, due to the fine particle size of titanium concentrate (the proportion of particles below 200 mesh reaches more than 75%), fine particles are easily drawn into the flue by the ventilation system during the smelting process and enter the dust removal system to form dust. Titanium smelters 15,000 tons of dedusting ash is produced every year, the loss of raw materials is relatively large, and a certain amount of fun...

Problems solved by technology

[0007] To sum up, since the above-mentioned secondary resources are mostly powder materials, the direct use of dust produces a large amount, which affects the air permeability. Therefore, the prior art needs to make them into blocks before reuse; however, the binder used for block making The high cost restricts the large-scale utilization of secondary resources to a certain extent
