Wet Dedusting and Desilting of Manufactured Sand：
Efficient wheel and countercurrent sand washing machines, combined with a high-efficiency fine sand recovery cyclone, are used for the efficient desilting and dedusting of wet manufactured sand, with a fine sand recovery rate of ≥98%.
Multi-stage Grading of Sand with Various Specifications：
Haiwang's efficient grading screen, coupled with a reasonable water spray design, achieves multi-stage grading of sand with various specifications, with high grading efficiency and minimal inclusion of fines.
Screening and Washing of Finished Products with Stone Powder Recovery：
Wastewater from screened finished products undergoes sand-water separation, and stone powder is recovered for reuse.
Recovery of Sand and Gravel from Wastewater in Commercial Mixing Stations：
Graded and dewatered equipment is used to classify and dewater wastewater from tank truck cleaning in commercial mixing stations. The graded sand and gravel can be reused, and the treated water can be reused as well.
Reuse of Wastewater from Wet Aggregate Production Lines：
Haiwang's efficient fine sand recovery cyclone is used to recover fine sand from wastewater in wet aggregate production lines. This is complemented by a high-efficiency thickener for water treatment, achieving wastewater reuse.
Water Intake Purification for Industrial Use：
Water intake undergoes sand removal, impurity removal, and purification to meet industrial water standards.
