In direct heat Rotary Dryers a continuous feed of wet particulate material is dried by contact with heated air, while being transported along the interior of a rotating cylinder / rotating shell acting as the conveying device and stirrer.

SSP offers Rotary Dryers in co-current (Parallel) and counter-current operation. In the former the wet material is exposed to the hottest air which enables heat sensitive or sticky material to be dried successfully.

In counter-current operation, dried material is exposed to the hottest air helping to achieve very low moisture content. The hot gas may enter at a very high temperature as high as 16000C.
