The River Sand Dryer developed by Zhengzhou Zhenggang Machinery Co., Ltd. is a high-efficiency rotary drying system designed for materials with high moisture content, such as river sand, sea sand, quartz sand, slag, clay, and mineral powder. It adopts optimized internal lifting blades and advanced heat utilization design to improve thermal efficiency, ensure uniform drying, and reduce energy consumption. During operation, wet materials enter the rotating cylinder, where lifting blades continuously raise and scatter the material for full contact with hot air. The dried material is then discharged as a finished product suitable for construction materials, foundry sand, mineral processing, metallurgy, and chemical industries.
Optimized lifting blade design fully disperses materials inside the cylinder, allowing hot air to contact the sand evenly and improve heat utilization.
Internal temperature and airflow control help ensure consistent moisture reduction and stable finished product quality.
Advanced heat exchange and heat recirculation design reduce energy consumption and improve production efficiency.
High-quality steel components, precision transmission, and durable sealing structure support continuous industrial operation.
The dryer can use coal, natural gas, diesel, oil, or biomass fuel according to production requirements.
Compact structure and modular design make transportation, installation, and routine maintenance more convenient.
Used for drying river sand for dry-mix mortar, construction materials, and sand processing production lines.
Suitable for reducing moisture in sea sand and yellow sand before screening, storage, or further processing.
Applied in quartz sand production lines where stable moisture control and clean finished material are required.
Suitable for drying ore slag, mineral powder, and other industrial powder materials before grinding or storage.
Used in construction aggregate, cement material, and building material plants requiring continuous drying performance.
Used for drying quartz sand, foundry sand, and industrial sand where stable moisture control, uniform drying, and high-quality finished sand are required.
