Quartz sand Filter material, natural quartz ore crushing, screening, washing made polygonal form, color white, no impurities, the density of 2.66, a silicon content of 99.3%, the mechanical strength of 7.5 degrees. At present, some areas use natural river sand, sea sand for Filter material, although the low cost, but the use of short, mechanical strength poor, broken easily. Quartz sand sand 3-4 times longer than the natural cycle. And the filtered water quality and stability, from the economic perspective, relatively, this Quartz sand or river sand and sea sand cheaper than many. 
1. Quartz crushing rate and the wear rate of the sand Filter material and should not be a big 1.5% (percentage by mass, the same below); 
2. Quartz sand Filter material shall not be less than the density of 2.55g / cm3. The use of density except special requirements; 
3. Quartz sand Filter material should be free of visible dirt, mica and organic impurities, Filter material flooding fluid should not contain toxic substances, clay content should not exceed 1%. Content of the light material is less than the density of 2g / cm 3 should not exceed 0.2%; 
4. Quartz sand Filter material of the LOI should not exceed 0.7% hydrochloric acid soluble rate should not exceed 3.5%.

Common specifications 
0.8 ~ 1.2mm, 1 ~ 2mm, 2 ~ 4mm, 4 ~ 8mm, 8 ~ 16mm, 16 ~ 25mm. 

Scope of application 
Quartz sand Filter material production is not only the best material for a single layer filtering, and anthracite Filter material and is ideal for double filtration. Refined Quartz sand Filter material used in drinking water filtration and other water purification process is more suitable for pre-treatment and recycling of water in petroleum, chemical, mining, metallurgy, thermal power, paper making, printing and dyeing, leather, food production and water, as well as wastewater recycling. 

Product features 
1. Single or double Filter material Filter Quartz sand Filter material particle size range, generally 0.5 ~ 1.2mm. Layer Filter material Filter Quartz sand Filter material particle size range, generally 0.5 ~ 0.8mm; 
2. In the various size range of Quartz sand Filter material, a particle size less than the specified lower limit should not exceed 3%, greater than the specified upper limit of the particle size should not exceed 2%; 
Effective size and uniformity coefficient 3. Quartz sand Filter material shall be determined by the use of units.
