Colored quartz sand | Feng Schroder Mining (certified) | quartz sand

 The beauty of using quartz sand where it is the main component of SiO2 silicon dioxide, but also contains iron oxide, clay, mica and organic impurities. Ordinary quartz sand and quartz sand. For the use of quartz sand quartz mine deep underground, by mechanical crushing, rolling washed crushed, sub-screen, pickling, washing, drying, sieving secondary refining quartz sand, the selection is made. Angular, high purity, free of impurities, high mechanical strength, color quartz sand, chemical stability. And for ordinary quartz sand using natural quartz deposits, by mechanical crushing, washing crushing roll, washing, drying and sieving made. Quartz sand processing plant also large quantities of sea sand, river sand. Solve the sewage serious phenomenon - the culmination of quartz sand quartz touted water filter: quartz sand is currently the most widely used in China, the largest amount of a water treatment filter quartz sand, which applies to single, double layer filter and rapid industrial high-purity water treatment of the supporting layer. I produced quartz sand, natural quartz deposit is a raw material, mining, crushing, washing, screening and other processed (high purity quartz sand subject acid treatment) Senior stained quartz sand, the appearance of multi-row spherical type white crystals, no impurities, high mechanical strength, chemical stability, high interception capability, long life cycle, good economic returns. Common Specifications: 0.5-1.0mm, 0.6-1.2mm, 0.8-1.6mm, 1.0-2.0mm, 2.0-4.0mm, 4.0-8.0mm, 8.0-16mm, 16-32mm, also according to user requirements with special grade specifications.
