Silica sands are produces form both loosely consolidated sands and weakly cemented sand stones ranging form Recent to Carboniferous in age.
Coarse-grained, well- rounded quartz sands are particularly suited for water treatment and are produced by the selective screening of sands form a number of quarries. Construction and silica sands are normally derived from the same quarry and their production is interdependent. Closely-sized water filtration sands are also produced from the sand making plant, which is a regionally important resource of sand and gravel.
In the sand production line, silica sand process includes four stages, they are washing, sieving, attritioning and drying. Silica sand plant produces industrial white silica sand having an extraordinarily high purity, with SiO2 > 99.5 wt%. The grain size ranging from 0.125 to 3.00 mm and our most modern High Tech. sieving facilities can provide different size distributions for different requirements and we can tailor make as per customer's requirements.
Silica sand making process
In the silica sand making process, jaw crusher is used as primary crushing machine, then go through the secondary crushing plant, the sand particles that meet the requirements enter into the sand making machine for making fine sand, while the others enter into the tertiary crushing plant for fine crushing, then go for sand making. The fine sand from the sand making machine must be washed by sand washer. Then dried by drying machine. Sometimes, we meed silica oowder, thus we need silica sand grinding machine, it can grind silica sand into powder. Sand making machine manufacturer
SBM is a munafacturer of construction and mining machines in China, and supplies all kinds of stone crushers and grinding mills for stone quarry and powder plant. We also design a complete crushing and screening plant for aggregate, gravel, sand, mineral ore according to the requirements of customers. Our aggregate crushing plant, gravel crusher machine, and sand making machine have been exported to many countries such as Israel, Cananda, Indonesia, philippines, Pakistan, India, Mlaysia, Egypt, kenya, Sri Lanka, Brasil, south africa, Zimbabwe, Ethiopia, Jordan, Peru, cuba, Macedonia.
Silica Sand
Silica sand is one of the most common varieties of sand found in the world, and is used in industrial processing, to make glass, foundry sand, as fill, paints, chemicals, ceramics and to create molds and castings in foundries. One of the major uses of silica sand in the modern world is as an ingredient in industrial concrete. Silica sand produces the bulk of a great deal of concrete, although some concrete bypasses its use for safety and strength reasons. Unlike construction sands, which are used for their physical properties alone, silica sands are valued for a combination of chemical and physical properties. These include a high silica content in the form of quartz and more importantly, very low levels of deleterious impurities, particularly clay, iron oxides and refractory minerals, such as chrome. They typically have a narrow grain-size distribution (generally in the range 0.5-0.1mm).
