READ MOREThe spray granulation dryer combines traditional spraying, granulation, and drying processes within a single rotary device, utilizing new technologies such as high-strength bricks, heat transfer, and internal classification, internal material return, and internal crushing.
Structural Principle:
The spray granulation dryer operates by pumping a high-pressure pump into a specially designed atomizing nozzle, where it is atomized into fine droplets. These droplets then contact the fine particle nuclei within the rotating cylinder, adhering to the surface of the nuclei. Under the action of the high-temperature drying medium, heat and mass exchange rapidly completes, causing the particles to grow. The enlarged particles are then screened, and the finer particles are returned as nuclei. Some of the powdered material is also returned as nuclei.
Technical Advantages:
1. High production capacity, strong operational flexibility, energy savings, and a shortened process flow.
2. Drying and granulation of solutions and high-temperature molten liquids are completed in one operation.
3. Stable operation, simple operation, and long service life.
4. Low operating costs and high thermal efficiency.
5. High product quality and high material yield. 6. The spray granulation dryer has a large output per unit
