The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes small granular product.

Ceramic: aluminum oxide, ceramic tile material, magnesium oxide, talc, etc.

At a high speed of drying ,after the spraying of the material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%~98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.

This is especially suitable for drying the heat sensitive materials.

Its final products own the good uniformity, mobility, dissolving capacity. And the final products are high in their purity and good in their quality. The production procedures are simple and the operation and control are easy.

The liquid with the moisture contents 40~60%(for special materials, the contents may reach 90%) can be dried into the powder of particle products once a time.

After the drying, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity. The product particle diameters, looseness and water contents can be adjusted through changing the operation condition in a certain scope.

It is very convenient to carry out the control and management.
