Sectional cooler

A sectional cooler is a type of liquid cooled rotary drum cooler used for continuous processes in chemical engineering. Sectional coolers consist of a rotating cylinder, a drive unit and a support structure. At each end of the drum there are stationary chutes for material feed and outlet. Depending on the size of the cooler the drum is pivoted on a shaft running through its axis, or is supported on running treads or external ring gears. The interior of the drum consists of several wedge-shaped chambers arranged around a central hollow shaft. This arrangement is completely surrounded by a jacket of water. In the wedge-shaped chambers are angled fins or shovels which move material through the cooler as the drum is rotated.
