    Direct Heat or Indirect Heat for Rotary Dryers | Bulk-Blog

    Nov 29, 2015 Indirect heat rotary dryers are most frequently used for products with small particle sizes that could result in excessive dust generation. They are also used for processes that require extreme control of the dryer exhaust. Indirect heat dryers depend on conduction and radiation to transfer the heat from the cylinder walls to the wet feed

    Direct- VS. Indirect-Fired Rotary Kilns & Dryers

    In an indirect device, there is not an internal gas flow acting as a heat source, so components such as lifting flights would offer no perceivable advantage. Heat is transferred to the bed of solids by conduction between the solids and the conduction between the solids and the hot, internal wall of the kiln

    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

    How Do Indirect Heat Rotary Dryers Work?

    How the Indirect Heat Dryer Works. Materials are fed into a rotary drum that is encased in a stationary refractory lined furnace. This furnace casing has a series of burners mounted down the length of one side firing into the furnace chamber. As the material progresses down the length of the unit, it is subjected to different temperatures in
