White quartz sand It is quartz particles crushed from quartz stone. Quartz, also known as silica, is a clay mineral with hard material, abrasion resistance and stable organic chemical properties. Quartz sand Rock, quartzite and vein quartz exist in nature. White quartz sandstone is pre compressed clastic rock, and the composition of quartz debris is more than%. The use of white quartz sand is because the particle size of the quartz sand in the filter bed of the filter material is lower than that of the white quartz sand in the two layers of filter material, and the fine anthracite filter material with high quality under the white quartz sand layer, so in other cases, even under the condition of high filtration rate, the filtering water of the filter material biofilter is better than that of the two layers of filter material biofilter. When white quartz sand is applied, it shall be applied together as much as possible. The stones with large production process flow are sent to the warehouse for selection of coarse and fine sand making machine. The sand washing machine is vibrated and selected to wash out the finished sand. The sand is dried by a dryer or of course dried.

White quartz sand filter is to add white quartz sand filter raw materials. The white quartz sand is used to block the mud and other residues in the water according to the interception and filtration. White quartz sand is different from ordinary sand. Because the strength of white quartz sand is very strong, the particles can be fine. Machine-made white sand If ordinary quartz sand is used, because ordinary sand is very easy to crush after passing through the softener, the sand will flow out seriously after a long time of use. Although the apparent density of manganese sand is high, its hardness is not as high as that of quartz sand. Therefore, the effect of filtering and blocking fine sand and other sundries is undoubtedly not as good as that of quartz sand.
