River sand dryer is mainly used for drying river sand as well as sand, slag, coal cinder and silica sand. This machine has reasonable design structure and convenient and simple use and it can quickly drying large quantity of sand.
1. Small coverage area: Compared with simple-cylinder dryer, the coverage area of this machine is decreased by 60% and the infrastructure investment is reduced by 60%.
2. Low energy consumption: The coal consumption is one third that of the single-cylinder dryer.
3. High drying efficiency: The heat efficiency of this machine is improved by over 40%.
4. Good drying effect: The final water content can be ensured below 0.1-1%.
