COOLING COVER TO BE SECURED EXTERNALLY TO THE ROTATING DRUM OF CEMENT MIXER TRUCKS, WHICH COOLS THE FRESHLY MIXED CEMENT CONTAINED THEREIN

摘要

The invention relates to a cooling cover to be secured externally to the rotating drum of cement mixer trucks, which cools the freshly mixed cement contained therein. The device is formed by a cover which is made to the dimensions of the rotating drums of cement mixers, adapted to the shape of same and fitted using a system of ties. The cover must be absorbent in order to allow a large quantity of water to accumulate, which, owing to the wind, evaporates as the truck moves and the drum rotates. The water may be distributed directly onto the cover. During the water evaporation process, the cover is cooled, thereby generating a thermal delta and a heat transfer from the cement contained inside the rotating drum to the cover, which reduces the temperature of the freshly mixed cement.
