Natural Sand VS Artificial Sand
Natural sand by the action of natural conditions (mainly weathering of rocks ) and the formation of particle size less than 5mm rock particles , known as natural sand . Artificial sand is to use jaw crusher , cone crusher and some other mining machinery for stone crushing derived come. After a flush of natural sand , river wash so feel more delicate.
Artificial sand material excellent stability. Artificial sand washing artificially selected raw materials , material uniformity , stability, mineral composition and chemical composition is consistent with the raw , not as complicated natural sand . Clean sand , no mud and other harmful impurities , stable performance .
Particle size -graded . An artificial sand washing , a fineness modulus , has only one graded . Its fineness modulus margin and single sieve sieve into a linear relationship. Just by measuring establish a linear relationship , measuring a single sieve sieve margin , you can accurately and quickly determine the fineness modulus . The general natural sand, having a fineness modulus , can have multiple graded .
Fineness modulus can be artificially controlled by the production process, according to different requirements of production, it is natural sand can not do .
Sand production mechanism to choose the right materials, the mechanism chosen raw sand is different for different purposes , usually in gravel , sand stone often used in the production of a lot , such as basalt , granite, travertine, limestone, pebbles , etc.
