Rotary Sand Dryers are one of the typical applying area of rotary dryers due to its reliable performance, high efficiency and low manufacturing cost. Our factory started to R &D Triple-pass Rotary Sand Dryers, which now has basically replaced conventional single-pass rotary dryer in sand drying plants.

Working Principles:
Material are delivered to the hopper by belt conveyor or bucket elevator . Then they go into the the charger tip by passing through the pipe of charger. When materials go into the tip of the dryer , heat carrier go into the dryer with material.After that ,they go into the discharging exit by passing through inner drum , middle drum and outer drum to go into the discharging storehouse .
After heat carrier pass through the dryer it needs cyclone dust collectors to gather in the material within the gas . If you want to reduce the amount of dust within tail gas , you should use bag duster or wet process duster to discharge .Then, materials are sifted and segregated qualified production by linear vibrating screen.
Consumption:
| Fuel | 1ton wet sand consume fuel | Calorific value |
| Coal | 10kg | 5500 kilocalorie/kg |
| Biological particles | 13kg | 4000 kilocalorie/kg |
| Natural gas | 6m3 | 8000 kilocalorie/kg |
