Description

TECHNICAL FIELD

[0001] The utility model relates to quartz sand sorting technical field especially automatic quartz sand sorting device. BACKGROUND

[0002] Quartz sand is quartz particle by quartz stone through crushing, screening and other processes. Quartz stone is a non-metallic mineral, and its mineral composition is mainly silicon dioxide. Quartz sand can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand and silicon powder according to quality. The silicon dioxide content and impurity content of various quartz sands are different. Since quartz sand contains impurities, the purity requirements of different industries are very different. In the semiconductor industry, the purity of quartz sand is extremely high. Therefore, the impurities in quartz sand are removed. In the construction industry, the purity requirement is relatively low, but the impurities in quartz sand also need to be removed. Therefore, the quartz stone is sorted to meet the purity requirements of different industries.
