Whether the product is a wet powder or a slurry, specially designed feeders transfer the product into the dispersion section of the dryer. A high speed rotor disperses the product in the drying zone. An induced hot gas stream as high as 600 °C provides the energy for instantaneous evaporation of the moisture within the feed material. Evaporation capacity of the largest unit is over 6000 kg/hr. Dried particles enter the classifying zone at the top of the dryer and fine de-agglomerated particles leave the dryer outlet to be collected down stream. Coarse particles are rejected by the classifier and are returned to the dispersion zone for further processing.
