  • Principles Of Heat Transfer As Applied To Rotary Dryers

    Principles Of Heat Transfer As Applied To Rotary Dryers

    In the case of a rotary dryer the material is being heated directly by the gases ie convection however the material is also getting heat from the shell of the rotary dryer through means of conduction in an indirect fired rotary kiln conduction is the only source of heat transfer

    The Truthabout Fluid Bed Dryer Efficiency

    Reality fluid bed dryers and rotary dryers are comparable in terms of fuel consumption while it is true that fluid bed dryers offer some enhanced heat transfer compared to rotary dryers fluid bed dryers use lower inlet gas temperatures typically around 900 vs the 2100 commonly used in rotary dryers so while rotary dryers may offer less thermal efficiency in theory the higher temperatures they employ
