Sand dryer is a three drum drying equipment developed on the basis of single drum rotary dryer. With simple internal structure and low energy consumption, the sand dryer is deeply loved by users, which greatly improves the labor productivity and application range. Sand dryer is generally suitable for drying materials with large specific gravity, especially for drying river sand, silica sand, yellow sand, sea sand, ore sand, iron powder, copper slag and other materials.
1. The rotary dryer has compact structure and reasonable layout, improves the heat exchange rate between materials and heat energy and ensures good drying effect.
2. The new lifting plate device is adopted to make the combination of materials and drying heat source more fully, and greatly improve the drying efficiency.
3. High automation degree. According to the water content and output of the materials, the frequency conversion control system is used to control the cylinder speed.
The sand rotary dryer is mainly used for drying river sand, artificial sand, quartz sand, dry mortar, yellow sand, slag, clay, limestone, and other materials with high wetness and high specific gravity. It is widely used in building materials, metallurgy, mineral processing, chemical, cement and other industries.
