Three Drum Dryer Sand Drying Equipment in Fly Ash Mineral Slag
Introduction:
Three drum dryer is composed of three concentric cylinders of different diameters in accordance with mathematical relationship and structure form, embedded in each phase. It is widely used for drying the fly ash, sand, mineral slag.
Features
1. Three drum dryer for drying sand with telescope-feed structure can dry the material quickly.
2. Simple design and self-insulation can improve the heat efficiency to exceed 80%.
3. Delicate structure and reliable operation.
4. Good drying performance decreases coal consumption.
5. Reduce land area for 50% compared to single drum rotary dryer, so construction investment is saved 50%, power and consumption saved 60%
