The Significance of Spray-Drying -

Apr 01, 2018 The main disadvantages of rotary atomizers are that they are limited in their ability to handle viscous feeds and cannot be used with short-form spray-dryers. Nozzle atomizers discharge feed liquids under pressure through an orifice as a high-speed stream that breaks into a spray of droplets. Operating pressures range from 250–10,000 psi.
