FIELD: oil and gas industry.

SUBSTANCE: invention can be used in cement, chemical-recovery and metallurgical industry. A device to cool a clinker comprises a rotary drum (2), installed in a water bath (1), facilities to charge (3) and discharge (4) the clinker. The rotary drum (2) along the perimetre is made from three and more strips of alternate width of convex curvilinear shape, rolled in the vertical plane in longitudinal direction bent along helical lines in transverse direction and bent along cuts, with bevelled walls in transverse-longitudinal direction arranged pairwise at the angle one to the other at both sides of strips to form broken helical lines along the drum perimetre that are directed oppositely to each other and broken helical surfaces with alternate pitch.
