Natural dehydration of artificial sand. At present, the method and process adopted in natural dehydration of domestic hydropower projects is artificial sand cutting, storage dehydration and artificial sand retrieving separately. Generally, after 3-5 days of storage dehydration, the water content can be reduced to less than 6%. And stable. The content of artificial sandstone powder and the initial water content vary. Generally, the content of stone powder is in the range of 10% to 17%. The water content is reduced to 8% to 10%. When the moisture content is reduced to 8% to 10%, the dehydration speed is obviously slowed down when it is reduced to about 6%. Generally, it takes 3 to 5 days. According to the daily production of 15,000 tons of finished sand and the amount of 1-15,000 tons of sand used per day, the finished sand warehouse has a stockpile of 50,000 m, and the natural dehydration time is about 5 days.
