Quartz sand production line and quartz sand production method

Abstract

The invention discloses a quartz sand production line and a quartz sand production method. The quartz sand production line comprises an ore washing and sorting system, a warehousing system, a sand making system and a water circulating system. The sand making system comprises a fine crushing line, a screening mechanism, a secondary processing line and a drying line. The fine crushing line is connected to the ore washing and sorting system. The screening mechanism is provided with a finished product discharge port and an inferior-quality product discharge port. The inferior-quality product discharge port is connected to the input end of the secondary processing line. The secondary processing line and the finished product discharge port are both connected with the input end of the drying line. The water circulating system comprises an acid supply device, an adjusting pool and a muddy water processing unit. The acid supply device is connected with the ore washing and sorting system. The input end of the muddy water processing unit is connected with the adjusting pool. The muddy water processing unit supplies purified waste water to a pickling line, a flushing and sorting line and a secondary processing line through pipelines. By means of the quartz sand production line and the quartz sand production method, inferior-quality product ores and waste water in the quartz sand productionprocess can be recycled, and production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of quartz sand production, in particular to a quartz sand production line and a production method. Background technique [0002] At present, British sand is a quartz particle produced by crushing quartz stone. Quartz stone is a non-metallic mineral, a silicate mineral that is hard, wear-resistant, and chemically stable. The color of quartz sand is milky white, or colorless and translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries. [0003] At present, the production of quartz sand is basically obtained by sequentially sorting ore washing, acid leaching, cleaning and drying, baking, magnetic separation and other pro...

AI Technical Summary

Problems solved by technology

The current quartz sand production line is relatively simple. Although continuous assembly line production can be achieved during the production process, a large amount of water will be needed in the processes of sorting and washing, acid leaching, cleaning and drying. The process of sorting and washing, crushing and screening A large amount of defective minerals will be produced in the waste, if these wastes are not handled properly, they will easily pollute the environment

In particular, the defective minerals still contain a considerable amount of quartz particles, but the current quartz sand production line does not recycle this part of the defective minerals and waste water, making the production cost of the current quartz sand production line high
