Ordinary quartz sand, namely SiO2 ≥ 90-99% Fe2O3 ≤ 0.06-0.02%, refractoriness 1750 ° C, large part of the appearance of the surface, yellow skin cyst on the surface. Ordinary quartz sand is generally a kind of water treatment filter material which is made of natural quartz ore, crushed, washed, dried and secondaryly screened; the filter material has: no impurities, no calibration, high density, high mechanical strength, The long life cycle of the sewage capacity line is an ideal material for chemical water treatment. The particle size range is 5-220 mesh, which can be produced according to the user's requirements. Main uses: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, sodium silicate, chemical, spray and other industries.
Ordinary quartz sand filter material acts as a filter, just as water penetrates into the ground through sand and gravel, blocking the suspension in the water, mainly for those fine suspensions. Quartz sand technology has reached the domestic leading level.
Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives and other industries. Can be transported by steam, train, and water. Industrial production is generally 50KG or 25KG packaging and export tons of bags. Common specifications: 0.5-1.0mm 0.6-1.2mm 1-2mm 2-4mm 4-8mm 8-16mm 16-32mm. (mm is the unit of mm).
Biomass Dryer is an Industrial Dryer that dries biomass materials with high moisture content. Biomass dryer can not only dry biomass fuel, but also dry food and agricultural by-products. The industrial dryer manufactured by our company adopts a microcomputer automatic control system. The temperature can be controlled during the drying process. Users can adjust the final moisture content of materials according to their needs. Biomass Rotary Dryer can choose different heat sources according to different wet materials. The main heat sources are gas, steam, electric heating and so on.
