Spray drying technology allows a variety of materials to be combined and then processed into uniform, free-flowing powders. Many materials are simply spray dried to produce dust-free powder. However, in many cases, the control of particle size distribution such as catalyst closure is to ensure the performance of the material itself.
Spray drying is a kind of dry granular powder used in the production process from slurry, which is a mixture of liquid and solid substances. The powder produced is completed by rapidly drying the slurry and using heated air. The mud is introduced into a stream of hot air through a rotating wheel or nozzle atomizer. For granular products produced by these two methods, the atomization disc provides a broad particle size distribution. Each method allows for consistent control of particle size distribution in spray drying.
