Summary:

The clean thermal medium heated by the heat source enters the drying chamber in a tangential form, forming a powerful vortex swirling airflow with the mechanical agitation mechanism. The wet material is metered into the drying chamber by a feeder, pulverized and dried by stirring and vortex flow. The top of the drying chamber is set with a particle size classifier. The fine powder that meets the drying requirements is discharged from the top of the tower and collected by the latter separator. The larger particles that do not meet the drying requirements are blocked by the classification ring, returned to the drying chamber, and continue to be pulverized and dried. After drying to qualified product, it is discharged out the drying chamber with hot air and collected by a separator. The clean exhaust gas is emptied by the induced draft fan.

Technical innovation:

1. It integrates drying and crushing together, and realizes the paste-like and filter cake-like materials to be quickly dried into powder at one time.

2. Short heat and mass transfer time, fast drying speed, suitable for heat sensitive materials.

3. Large drying strength, high thermal efficiency, and smallequipment volume.

4. The structure of the dryer is reasonable, and the installation and maintenance are convenient and simple.

5. Tangential air intake structure, increase the drying strength andoptimize the heat and mass exchange effect.

6. The reasonably designed annular structure effectively increases wind disturbance and greatly enhances heat exchange efficiency while cleaning large particle materials.

7. The large size mixing and dispersing structure ensures the mixing of materials and hot air, and ensures the enhancement of heat and mass transfer throughout the heat transfer process.

8. The top tangential wind ensures the spiral drying wind path.

9. The gas seal structure ensures the transmission gap has no powder leakage.
