The wet sand making process utilizes water as an auxiliary medium, incorporating water application throughout the entire sequence of crushing, screening, and conveying. This approach suppresses dust generation at the source, eliminating the need for complex dust removal equipment; consequently, it ensures a clean production environment and facilitates easy compliance with environmental standards.
Mechanically produced sand that has undergone this washing treatment features clean surfaces, well-rounded grain shapes, and low silt content. Its quality closely rivals that of natural river sand, enabling it to meet the stringent requirements for high-grade aggregates demanded by critical infrastructure projects, such as highways and railways.
Furthermore, this process remains unaffected by fluctuations in the moisture content of raw materials, ensuring continuous and stable production. It effectively mitigates the issues—such as material clogging and reduced output—that often plague dry sand-making processes when materials are damp. Simultaneously, the fine sand recovered during the washing process can be repurposed for the production of lower-grade concrete or bricks. This comprehensive resource utilization rate exceeds 95%, thereby not only enhancing the market value of the finished sand but also boosting the economic value of the by-products.
By utilizing water to suppress dust and enhance quality, the wet sand making process stands as an ideal solution that successfully balances the imperatives of environmental protection and product quality.
