Description
Technical field
The present invention relates to a kind of pellet, more particularly, the present invention relates to a kind of siliceous raw material mine tailing pellet, simultaneously, the invention still further relates to a kind of preparation method and purposes of said siliceous raw material mine tailing pellet.
Background technology
At present, make the used siliceous raw material of glass, general granularity requirements maximum is no more than 0.71mm, and 0.1mm preferably is no more than 5% with the lower section.Siliceous raw material is being carried out in the course of processing; Utilize natural silica Sand to carry out ore dressing to handle no matter be; Still utilize natural crystal (for example: quartzite, vein quartz, sandstone etc.); Carry out fragmentation and classification, all can produce the powder below a large amount of 0.1mm, powder can reach the weight percent of natural crystal more than 20%.
The too much problem of bringing of powder is:
1, the powder below the 0.1mm is given it up as mine tailing, not only waste resource, land occupation, and pollute, influence environment.
If 2 this part powder still use as frit, certainly will cause in the glass batch powder too much, can there be following shortcoming again:
(1), glass batch is prone to form siliceous material group in mixing process, its is difficult for fusing, in formation calculus on glass;
(2), glass batch is prone to layering in course of conveying, influence the homogeneity of glass;
(3), since in the glass batch powder many, be prone to fly upward, contaminate environment, influence the homogeneity of glass and the work-ing life of kiln.
Summary of the invention
The technical problem that the present invention will solve provides a kind of siliceous raw material mine tailing pellet that improves the Mineral resources utilization ratio, reduces land seizure and environmental pollution; Simultaneously, another technical problem that the present invention will solve provides a kind of preparation method of this siliceous raw material mine tailing pellet, and this method technology is simple, and use equipment is few; Also provided simultaneously the purposes of this siliceous raw material mine tailing pellet.
For solving the problems of the technologies described above, the invention provides a kind of siliceous raw material mine tailing pellet, this pellet is prepared by following method:
