The triple pass rotary drum dryer prolongs the time of drying, improving production capacity by 50-80% compared to that of monocular dryers.

Features
1. The final percentage of moisture for the slag is ensured to be below 0.5%, making the industrial dryer ideal for dry-mixed mortar and slag powder production lines.
2. The self-heating efficiency of the cylinder can reach as high as 70%.
3. Coal, gas or oil can be used as fuel for drying lumps, granules and powdery materials with a granularity below 20mm.
4. Compared with monocular dryers, our rotary drum dryer takes up 50% less floor space and uses 60% less energy.
5. The final water content index can be easily adjusted according to need.
6. The triple drum dryer doesn't need a rack wheel but uses a riding wheel for transmission.
