Rotary dryers are capable of handling a wide range of throughput – typically anywhere from 1 TPH – 200 TPH. Rotary dryer capacity is a function of drum size and allowable air velocity. What information is necessary to design a rotary dryer? Rotary dryer manufacturers will require the following information to design a rotary dryer:
Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results.. The retention time required for a given application is determined through balancing the necessary process parameters – particle size distribution, air flow velocity, temperature, and more – with the …
Partition plates increase the heating surface. Drying may be by hot air or exhaust gases from other operations. If this drying gas has a deleterious effect on the product, then an indirect type of dryer can be supplied. A further derivation is the Tedrow Steam Dryer.
