PDF Rotary Kiln Handbook NEW Ahmad Reza Jamali

In a rotary kiln, material is typically not showered like in a rotary dryer, but rather, slides along the interior of the rotary kiln. This results in lower heat transfer between the material and the gas. Because of this, drying material in a rotary kiln takes much longer than in a rotary dryer.
