Sectional cooler

[1] Sectional coolers consist of a rotating cylinder ("drum" or "shell"), a drive unit and a support structure.

In the wedge-shaped chambers are angled fins or shovels which move material through the cooler as the drum is rotated.

As the drum rotates, the fins on the inside faces of the wedge-shaped sections convey the material to other end of the cooler.

The rotation causes a constant mixing of the product in the chambers, providing good heat transfer and increasing efficiency.

[4] The purpose of sectional coolers is usually to reduce the material temperature enough that it can be handled with other machines such as conveyor belts and mills.
