Method for producing dust-reducing and dust-absorbing materials from raw materials for non-metallic minerals and cement plants

Abstract

The invention belongs to the technical field of material preparation, and discloses a method for producing dust-reducing and dust-absorbing materials from non-metallic minerals and raw materials produced in a cement factory. The block is calcined to obtain quicklime; the quicklime is cooled at room temperature, dried and pulverized to obtain calcium carbonate powder; the non-metallic mineral is dried and ground to obtain non-metallic mineral powder; the calcium carbonate powder and the non-metallic mineral powder are mixed, and ball-milled to obtain nano-powder; The dust-absorbing material is added, mixed with water, poured into a mold for drying, and air-dried to obtain a cavity-shaped dust-reducing and dust-absorbing material. The raw material of the invention is convenient to obtain, low in cost, can effectively reduce the cost of material preparation, and the dust-reducing and dust-absorbing material can be recycled after dust absorption, thereby effectively saving resources; adding the dust-absorbing material can enhance the adsorption force and generate stronger dust particles. The adsorption capacity is better, and the vacuuming effect is better.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a method for producing dust-reducing and dust-absorbing materials from non-metallic minerals and raw materials in cement plants. Background technique [0002] At present: Cement production in the cement production workshop will generate a large amount of dust, including raw material dust, dust generated in the production process, and product dust. The dust diffuses in the production workshop and enters the respiratory tract with the breathing of the production workers, which has adverse effects on human health. In order to reduce the diffusion of dust, the cement production workshop is equipped with a dust treatment device, but the purchase cost of the device is high, and it is difficult to achieve large-scale promotion and use; and the ordinary dust removal and dust reduction materials have poor adsorption effect on the dust in the cement workshop, which ...

AI Technical Summary

Problems solved by technology

[0002] At present: the cement production workshop will produce a large amount of dust, including raw material dust, dust generated during the production process, and product dust. The dust permeates the production workshop and will enter the respiratory tract with the breathing of production workers, which will adversely affect human health.

In order to reduce the diffusion of dust, the cement production workshop is equipped with a dust treatment device, but the purchase cost of the device is high, and it is difficult to realize large-scale promotion and use; and the ordinary dust removal and dust reduction materials have poor adsorption effect on the dust in the cement workshop, and it is impossible to realize the dust removal in the production workshop. dust down

[0003] Through the above analysis, the problems and defects of the existing technology are: the purchase cost of the dust treatment device is high, and it is difficult to realize the popularization and use; the ordinary dust removal and dust reduction materials have poor adsorption effect on the dust in the cement workshop, and the dust reduction in the production workshop cannot be realized.
