1. The material liquid is directly split into droplets
If the feed volume of the centrifugal spray dryer is relatively small, it will move to the edge of the dispersion plate due to the centrifugal force, and the liquid ring bulging on it will act on the viscosity, surface tension, and centrifugal force of the material. And the shape and smoothness of the dispersion plate are related. If the centrifugal force is greater than the surface tension of the droplets, the spherical droplets will split and atomize, but there will be a small amount of large droplets.
2. the filaments split into droplets
If the centrifugal spray dryer feeds a large amount of material and liquid, and the rotation speed of the dispersing disc is relatively fast, then the hemispherical droplets on it will be drawn into filamentary liquid lines. And, there is a proportional relationship between them.
3. the film splits into droplets
When the centrifugal spray dryer is working, continue to increase the liquid flow, but the liquid filament and the diameter of the filament will not increase. Then the liquid filaments will form a thin film through adhesion. When it is thrown out by centrifugal force, it will form droplets and have a wide distribution. If the rotation speed is further increased, the liquid can be ejected at a high speed, and then atomized.
