Sizing Of A Rotary Dryer - Blogger

Jan 16, 2019· Rotary dryers, called the "workhorse of chemical dryers", belong to the most widely used class of continuous dryers in process industries. These dryers are suitable for relatively free-flowing, non-sticky and granular materials; for example, almost all types of crystals after crystallization and washing. Typical applications of rotary dryers are in drying o table salt, sodium sulphate ...

This paper analyzed the drying process of the household gas clothes dryer (GCD) based on the principle of heat and mass transfer. The drying models in three scenarios were established: natural gas burned in combustion chamber, ambient air mixed with exhausted gas in hot gas duct, and clothes were dried in the drying drum. The simulation of the drying process was performed on MATLAB software.
