Quartz sand filter is the most widely used in China, the largest amount of a filter, it applies to single, double quick filter and industrial high-purity water treatment of the supporting layer. I produced the ordinary quartz sand is made from natural quartz ore, by crushing, screening, washing, drying, secondary screening is made. Multi-angular quartz sand, nearly spherical, small impurity content, high mechanical strength, interception capability, chemical stability. Combined filter container for trapping suspended solids in water colloidal particles of impurities. Refining quartz sand Scope: Our company produces refined quartz sand filter is made of high purity quartz ore, processed by crushing, screening, washing together. Its role is to combine and filter container for trapping suspended solids in water colloidal particles of impurities. Used in power systems, multi-media filters, ion exchange, activated carbon filter mat and water containing acid water filtration components. White appearance, more angular, no powder deposited on the surface of quartz sand, can pickling (if required). The technical requirements of refined quartz sand filter: 1, refining quartz sand crushing rate and the wear rate should not exceed 1% of the sum of (percentage by mass, the same below). 2, refining quartz sand filter should not be less than the density of 2.55g / cm3, the use of density with special requirements are excluded. 3, refining quartz sand filter should be free of visible dirt, mica and organic impurities, filter flooding fluid does not contain toxic substances. Light material content of clay content should not exceed 1%, density is less than 2g / cm3 should not exceed 0.05%. 4, quartz sand of the LOI should not exceed 0.4%. 5, quartz sand hydrochloric acid soluble rate should not exceed 0.06%. Refining quartz sand particle size: 1, in various size range of refined quartz sand, and less than the specified lower limit of the particle size should not exceed 3%, greater than the specified upper limit of the particle size should not exceed 2%. 2, the effective diameter of fine quartz sand filter is determined by the use of units. Refining quartz sand filter Common Specifications: 0.5-1.2mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm, according to customer demand production of various specifications. Refining quartz sand filter packing and storage: double or single woven bag, 50 kg.
