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 Rotary Dryer Operating Principle Classifications Uses The direct heat dryers are the simplest and the most economical class they are used when direct contact with the hot gas or air is not detrimental to the fed rotary dryer can also be said to be indirect when the heating medium is separated from contact with the solid by a metal wall or tube read also spray dryer types of rotary dryers Rotary Dryers Feeco International Inc Indirect rotary drum dryers unlike direct dryers indirect dryers do not rely on direct contact between the material and process gas to dry the material instead the rotating drum is enclosed in a furnace which is externally heated Best Practice Manual Dryers Heat may be supplied by convection direct dryers by conduction contact or indirect dryers radiation or volumetrically by placing the wet material in a microwave or radio frequency electromagnetic field over 85 percent of industrial dryers are of the convective type with hot air or direct combustion gases as the drying medium

Rotary Steam Tube Dryers Louisville Dryer Company Louisville steam tube dryers have proven superior to other types of indirectheat dryer installations in which hot gas rather than steam is used as the heat source maintenance savings alone have often prompted replacement of other dryer systems with the steam tube dryer Rotary Dryer Schenck Process The indirect heat rotary dryer design provides for heating under oxidizing reducing or inert atmospheric conditions the rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length with heat transfer indirect and through the cylinder wall the gas velocities within an indirect dryer Bartlettsnow Rotary Dryers Schenck Process The indirect heat rotary dryer design provides for heating under oxidizing reducing or inert atmospheric conditions the rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length with heat transfer indirect and through the cylinder wall the gas velocities within an indirect dryer
