Preparation method of mineralizing agent and binding agent used for silica brick production through co-milling

Abstract

The invention relates to a preparation method of a mineralizing agent and a binding agent used for silica brick production through co-milling, which is characterized in that mineralizing agent mill scale, lime, binding agent calcium lignosulfonate dry powder and water are added into a ball mill together, through the co-milling of the mineralizing agent and the binding agent, the processes of slaking and finely milling the lime, finely milling the mill scale and dissolving the calcium lignosulfonate dry powder into a solution are integrated, and simultaneously heat generated in the milling process is utilized to accelerate the dissolution of the calcium lignosulfonate dry powder; and finely milled slurry is injected into a stainless steel round vibration sieve through a pipeline, lump materials are sieved out, and sieved material slurry flows into a corrupting pool to be corrupted and homogenized. The invention has the advantages that a mineralizing agent and binding agent co-milling mode is adopted to shorten pug mulling time and improve the production efficiency and the product quality; and the defects of complex mineralizing agent and binding agent preparation process, long procedure and the like are solved.

Description

technical field [0001] The invention relates to a preparation method of a mineralizer and a binder for the production of silica bricks, in particular to a preparation method for co-grinding a mixture of the mineralizer and the binder. Background technique [0002] At present, the usual preparation method of mineralizers and binders in the production process of domestic silica bricks is: the mineralizers and binders are mixed separately, and finally mixed. The iron scale fine powder is prepared by drying, fine grinding, and screening production processes; the milk of lime is prepared by digestion, wet grinding, blending, and stale production processes; the pulp solution is prepared by calcium lignosulfonate dry powder, adding an appropriate amount of water, Stirring and preparation at a certain temperature (a certain temperature is reached through the consumption of external energy). The preparation process is long, requires a lot of equipment, and occupies a large area, and...
