Triple pass rotary dryer

Triple pass rotary dryer is used to dry ore slag, flyash, quartz sand, etc, the size should be below 20mm.
Triple pass rotary dryer
is low coal consumption,after drying ,the moisture can be 0.5-1%,which is the ideal drying equipment forore slag.The outlet temperature is below 50 degree, don't need to coll again.
