Indirectly heated drum dryers

Indirectly heated drum dryers

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

    Indirect dryers heat up the drum and its walls start emitting heat as well effectively transferring it to the material inside. The radiation ensures even heat distribution and renders lifters useless since there is no air flow inside the vessel. Lifters are completely unnecessary in such setups. Another benefit is that you do not have to worry
