Rotary dryer - Wikipedia

A wide variety of rotary dryer designs are available for different applications. Gas flow, heat source, and drum design all affect the efficiency and suitability of a dryer for different materials. The stream of hot gas can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The direction of gas flow combined with the inclinationof the drum determine how quickly material moves thr

Heat of compression rotary drum dryers - Atlas Copco

Rotary drum dryers use this heat to regenerate the desiccant. Little to no additional heat is needed to reach an acceptable dewpoint. This is what makes rotary drum dryers extremely energy efficient. Lifecycle cost Energy can constitute up to 80% of the total lifecycle cost of a dryer. You therefore need to look closely at energy efficiency when selecting a dryer.

A single-drum dryer consists of hollow metal cylinders mounted on a horizontal axis and mechanically rotated with variable speed control. The drum is heated by steam, hot water, or other heating medium condensing on its inside surface, the drying effect being obtained by the transfer of heat from the inside of the drum through its metallic wall to a film of material spread over its external surface [13] .

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 refractory is heated and transmits the heat from the refractory to the material by direct contact. Radiation is also present in all of these scenarios, because heat
