Purity index of glass grade silica sand

The glass industry is the largest application field of quartz except for construction sand. About 60 million tons of quartz raw materials are used in glass every year. Transparency, mechanical strength, chemical stability, etc. are the most important properties that quartz gives glass. In the composition of ordinary silicate glass, SiO₂ generally accounts for about 65% to 75%.

sand washing and screening plant
LZZG silica sand washing plant was export to India, Sri Lanka, Malaysia and other places, help customers producing clean silica sand.
Modern float glass generally requires that the SiO₂ content in the quartz raw materials is above 96%, the Al2O3 content is below 2%, the Fe2 O3 content is between 0.01% and 0.1%, the particle size is about 0.4mm, and the particle size is above 0.5mm and below 0.1mm. The particles shall not exceed 5%. Special glass, ultra-white glass, precision optical glass, etc. have stricter requirements on the chemical composition of quartz raw materials.

Silica sand washing and purification plant

The glass grade silica sand washing plant mainly includes screening, washing, dehydration, fine sand recovery, solid-liquid separation, sludge dewatering and the like. The material is effectively screened, washed and dewatered throughout the system. Save resources and reduce water consumption. The entire production line has excellent continuous working performance and convenient maintenance. Long service life, easy to move and excellent effect. At the same time, it ensures no pollution and meets environmental protection requirements.
