Washed sand is construction sand that is obtained after the natural silica sand is washed by a sand washing machine and meets the construction standards of various places. Both artificial sand and natural sand contain certain impurities. If such sand is used for the construction of the project, it will result in a strong degree of engineering. Therefore, the sand washing machine equipment should be used to clean the impurities in the prepared sand to complete various construction requirements. The silica sand washing production line is a system solution for the problems of dry piles, tail water purification, dry waste discharge and other issues. It mainly includes screening, cleaning, dehydration, fine material recovery, solid-liquid separation, sludge dewatering and other aspects. 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
