Abstract
Mine refuse as industrial waste is treated through crushing, magnetic dressing, water washing, sieving and grading into coarse sand, mild sand, fine sand and residuum for mixing with sand. Using the waste in producing sand for building can meet the requirement for building and reduce environmental pollution. In addition, the sand has low production cost.
Description
One, technical field
The present invention relates to a kind of manual manufacture building sand method.
Two, background technology
The ground building sand much is to get sand from rivers or riverbed in China, and excessive exploitation causes a hidden trouble for rivers safety.Existing country has prohibited in the river course, the Congjiang digs sand, and sand source anxiety appears in some areas.The machine-processed artificial sand that rock is pulverized is also arranged, but its cost of manufacture is higher, speed is slow, can not satisfy growing needs.
Three, summary of the invention
The present invention is in order to utilize industrial waste, to be made as building sand.
The raw material that adopts is the industrial waste slag, at first slag is pulverized, and carries out magnetic separation then, and through the washing sizing screen needed carse, medium and small sand of hanking, residuum carries out mulling again to be handled again.
The sand that uses this method to make, it is required not only to have satisfied building, and industrial waste is utilized again, has reduced industrial waste to the pollution of environment with protected the river course, and cost of manufacture is also low.Through relevant department this sand and concrete product thereof are detected, every index all meets related standards.
Four, embodiment
At first blast-furnace slag is pulverized through pulverizer, by in the transfer roller input magnetic separator ferruginous slag being selected, but generally select 2-3 all over Ex-all, send into afterwards in the rinsing machine superfine dust is washed out, again through molecular vibration sieve be settled out thin, in, thick three kinds of varigrained sand, remain bigger particle and pass through the sand that sand mill grinds out desired particle size again, water rinses out dust in the process of lapping, and slag is made full use of.
Claims (1)
- A kind of manual manufacture building sand method, its raw material is a slag, it is characterized in that: at first slag is pulverized, carried out magnetic separation then, through the washing sizing screen needed carse, medium and small sand of hanking, residuum carries out mulling again to be handled again.
