  • Principles of Heat Transfer as Applied to Rotary Dryers

    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, cooler, or kiln works.

  • A study of particle motion in rotary dryer

    Rotary dryers are a class of dryer commonly used in industry to dry particulate solids (Keey, 1972). They are made of a long cylindrical shell that is rotated. The shell is usually slightly inclined to the horizontal to induce solids flow from one end of the dryer to the other. In direct heat rotary dryers, a hot gas flowing through the dryer
