Dried sand is a building material, made from ordinary sand through a series of processes including drying, screening, grading, decontamination, and further drying, specifically used in industries such as thermal insulation sand slurry for construction, foundry, wastewater treatment, and artificial beaches.

Primarily used for casting medium to large castings. The quality of molding sand and sand molds is relatively easy to control, but the dimensional accuracy of castings is poor. Sand molds require specialized drying equipment, and the production cycle is longer, thus dry molds are gradually being replaced by self-hardening sand molds in many aspects.
