AI Technical Summary
In existing high-tower granulators, the sprayed slurry tends to stick to the inner wall of the tower, and the uncooled granules tend to stick to adjacent granules, resulting in a reduced output rate.
An air distribution sleeve and a vibration device are installed inside the tower. The air distribution sleeve blows airflow through ventilation holes to prevent the slurry from sticking together. The vibration device uses a vibration plate and a cam to make the particles roll and cool, extending the cooling time and preventing particles from sticking together.
It effectively prevents slurry from sticking to the wall, improves particle cooling effect, reduces loss, and ensures output rate.
