Artificial sand, also known as machine-made sand, as the name suggests is the use of machinery and equipment artificial sand, generally refers to rocks or river pebbles from the river digging through the VSI impact crusher (commonly known as "Sand") processing to become suitable for building usesand. Rough the artificial sand the surface of the particles, the more angular, the bond between the aggregate and cement, aggregates, mechanical bite force than with natural sand concrete high strength concrete with artificial sand.

Yu Feng artificial sand production line includes two processes of production lines and mechanisms of the mechanism sand dry sand wet production line, sand production line equipment can be used in the bone of the hard limestone, granite, basalt, river gravel, the rule of multi-residue and other materials materials and artificial sand operations, suitable for the application of the water, building materials, highway, urban construction and other industries.

Sea sand is eroded and has not been downplayed the sand come from the sea and rivers where the junction. Sea sand containing chloride ions ingredients, ingredient, if excessive, in the concrete mixing used in engineering construction reinforced serious corrosive effect.

To this end, in August 2004, the Ministry of Construction on the introduction of a strict building with views of the sea sand management, noted in the submissions, sea sand mining, desalination processing, concrete mixing process, there are stringent provisions, and sea sand used in construction projects must go through specialized desalination, if you want to use in reinforced concrete, the chloride ion content of sea sand should not exceed six ten thousandths.
