SD-300 spray granulation coating machine multifunctional one-step granulator

Features

The SD-300 spray granulation and coating integrated machine can be used for mixing, drying, granulating and coating various granules and pellets.

working principle

Granulation principle: Top spray device The top spray device is composed of a tapered material tank and an expansion chamber. The material forms a fluidized movement from bottom to top and top to bottom. In the cone-shaped pot, the material reciprocates to form a fountain-like fluidization. In the state, the spray gun sprays the liquid to make the material evenly contact the slurry and form a liquid bridge first, and then form a solid bridge to cause large particles. There are multiple atomization head installation ports on the top of the expansion chamber, which can be used to spray atomized liquid during the granulation and coating process.

Coating principle: The bottom spray device is an important breakthrough in coating technology, making it possible to coat small particle size materials. With the development of technology, it has been possible to coat powders as small as 50 µm. The bottom spray device is composed of a cone-shaped pot body and a deflector. The bottom of the pot adopts a double air duct structure to control the airflow state inside and outside the deflector. The material moves upwards at a high speed in the guide tube, enters the expansion chamber and then falls outside the guide tube, and circulates in this way. The spray head atomizes the droplets from bottom to top in the center of the guide tube, and the droplets are evenly spread on the surface of the particles to form a small coating film. During this process, the thickness of the coating film increases steadily and dries until the coating is completed.
