High Operating Ratio 1.0×10m 50t/H Rotary Drum Cooler

Air cooler is also called air heat exchanger, referred to as air cooler.. Mechanical air cooler is a kind of flue gas cooling equipment produced by our company. This product is an indirect tube heat exchanger. The heat medium to be cooled is fed from the upper part of the cooler. The heat medium moves turbulently in the pipe and transfers the heat to the cooling pipe, and then turns from the lower part of the cooler to the outlet bin. Drained, the dust in it is retained in the ash bin by inertial force. The cold wind outside the densely packed tubes is sent by several axial fans on the side of the densely packed cooling tubes. This part of the cold wind makes a circular movement outside the row of tubes in the fork row to take away the heat of the cooling tubes and cool it. The other side of the device is discharged into the atmosphere.

Rotary Cooler Working Principle:

Clinker with high temperature goes into the cooler through the feeding device, and the cooler will rotate to drive the materials to conduct heat exchange with the air, and with the constant rotation of the kiln according to the designed inclination and rotating speed, the materials will also periodically roll and move forward inside the kiln, so that the raw materials are send from the feeding end to the discharging end and cooled to below 200℃ in the time period when the materials go through the rotary kiln.

Rotary Cooler Features:

The mechanical air cooler is mainly composed of upper header, cooling tube bundle, fan, ash hopper, takeover, unloader, etc.
The tube bundle is the basic component of heat transfer. It is composed of a steel pipe, a tube box, a support beam and a side beam. When the cooled medium passes through the steel pipe, its heat is taken away by the air flowing outside the pipe, and the medium in the pipe cool or condense.
The fan is used to drive air through the tube bundle and take away the heat of the cooling medium, thereby promoting the cooling of the heating medium. The air cooler uses an axial fan.
