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.

More than any other factor, the method of conveying the feed through the dryer governs the outward appearance of a dryer and limits its operating parameters. While free-flowing granules can be handled in a variety of ways, more awkward materials like loose fibres, which can tangle together, and very wet sticky feeds require special techniques. The following table illustrates the range of conveying methods adopted industrially.
