  • It is good for raw materials that are large in viscosity,paste material,which the other equipment can not replace it. 
  • More varieties and wide application in drying with lower temperature.
  • The nozzle is simple in structure,convenient in maintenance and low cost in operation.

Principle

The clean air is heated and entered into drying tower,the raw material inside the tower is atomized into fine mist through muzzles of two or three flows. The raw materials carry out heat exchange with the hot air rapidly to evaporate the moisture (solvent) in the raw materials. The moisture or solvent is discharged accompany with hot air, then the power product is produced.

* Note

  • The factor of raw material feeding can be increased suitablely for the raw material that the volume before and safter may be changede greatly.
  • Revolution for 2000 type:6rpm, for 3000 and 5000 type: 4rpm;
  • For special requirements, we can design and manufascture too.
  • The specification of Tank insert is same.
