  • Principles of Heat Transfer as Applied to Rotary Dryers

    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, cooler, or kiln works. Knowing how heat transfer works can help in sizing a machine, and can also help to anticipate where heat will be lost in a system. Even though
