Triple pass rotary dryer Process introduction:
Wet material feed into the hopper by loader, then through vibrating feeder and belt conveyor transferred into dryer cylinder, where it comes into contact with the hot air generate by burner at high temperature and begins preliminary drying.
In the first cylinder the material undergoes preliminary heat exchange with the hot air, and most of the moisture in the material is evaporated. Subsequently, the material enters the second cylinder (second cylinder), where it comes into contact with the hot air at a slightly lower temperature, continues the drying process, and removes the remaining moisture.Finally, the material enters the outermost cylinder (third cylinder) and undergoes the final heat exchange with the hot air at a lower temperature but with a faster flow rate, ensuring that the material reaches the required degree of dryness.

The three-drum dryer is not only suitable for drying various types of sand (such as river sand, sea sand, mountain sand, etc.), but can also be used to dry other granular materials (such as coal powder, mineral powder, etc.). This wide applicability makes the three-drum dryer valuable in many fields.
