Abstract
In a rotary tube cooler for indirect cooling of pulverized to granular material with a revolving drum, the drum shell of the rotary tube cooler is formed of a tube system through which a liquid cooling medium is conducted. The tube system comprises either tubes meandering in longitudinal direction of the rotary tube cooler, or be formed of spiral tubes, or the combination of meandering and spiral tubes. The tubes are welded together. The feed of the cooling medium and the discharge of the heated cooling medium occurs via swivel joints. Connected downstream is a device for utilization of the waste heat of the rotary tube cooler.
