Application of Rotary dryer : It is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; therefore, it has been widely used. Working Principle of Rotary dryer : After wet material is put into the hopper, the stove generates hot wind. Then wet sawdust is sucked into the pipes by the exhaust blower(fan) , flowing and go though the curving pipes and buffer(drying chamber) of dryer, thus the wet material is dried, and the dried material is discharged from the outlet with air lock. This type of dryer is suitable for drying heat sensitive material which is light and small like sawdust, rice shell, milled stalks etc. General Wet material can be dried in a few minutes. Compared with rotary dryer, it has the advantages of low energy comsumption, low cost.
