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 desired outcome; it can then

= 89.28 Residence time of rotary dryer typically ranges at 5-90 minutes (Couper, Penney, Fair, & Walas, 2005), therefore the computed value is acceptable. CALCULATION OF SHELL DRYER THICKNESS & OUTER DIAMETER Considering the material to be used is Carbon Steel (SA 285, Grade C) because it can withstand up to 343.33 C
Rotary Drum Dryer Design Calculations. If you bought a used dryer or one without its user manual, the capacity still can be calculatedou cant tell a dryers capacity from its external size aloneou must take the measurements of the interior drum that holds the clothesnce you have the right measurements, you simply calculate the volume to determine how much space is in the
Rotary Dryer Diameter Calculation. Rotary dryer diameter calculation Calculate the diameter of the dryer If the drying time can be determined in some way In an existing drying unit or in a laboratory under conditions that are present in the dry condition this time is used for mechanical design of the dryer which is used for a small amount of drying when the material stays there longer than usual
