Quartz sand filter material to the local natural quartz ore as raw material, by mechanical crushing, screening, distribution of refined by-stage pipeline. The product as a result of relatively strong material with a relatively stable physical and chemical properties, does not affect the water filtration, good mechanical strength, long-term use is not easy to wear and tear and fragmentation, the high silicon content, corrosion resistance, and strong adsorption is widely used in heat power station, petrochemical industry, sewage treatment, machinery, pressure filters, ion exchange
