Direct and Indirect Heat Rotary Dryers

Direct and Indirect Heat Rotary Dryers

The rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length With heat transfer indirect and through the cylinder wall, the gas velocities within an indirect dryer are low as compared to a direct heat dryer, and correspondingly, the off-gas system is smaller and more economical
