Principles of Heat Transfer as Applied to Rotary

Whether you are using a rotary dryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods of heat transfer to carry out their jobs.Heat transfer is how heat moves from one source to another. Understanding the types of heat transfer, and how they differ, is an important part in understanding how a rotary dryer

Rotary dryer - Wikipedia

The rotary dryer is a type of industrial dryer used to reduce or minimize the moisture content of the material it is handling by bringing it into contact with a heated gas. The dryer is made up of a rotating cylinder ("drum" or "shell"), a drive mechanism, and a support structure (commonly concrete posts or a steel frame). The cylinder is inclined slightly with the discharge end is
