Just as its name implies, a cooling machine is a mechanical machine used for cooling materials. Generally speaking, a cooling machine is composed of feeding mouth, discharging mouth, plenum and driving device, and the cooling machine needed by the common industry adopts forced air cooling system. When the cooling machine is running, the materials to be cooled are imposed on the forces of reciprocating motion on the trolley driven by the driving device, so that the materials can be quickly cooled in the plenum. Usually such industries as cement and fodder will use cooling machines.

Cooling machine is one of the important machines of the rotary kiln system and its functions are to cool the clinker from the rotary kiln from 1000-1300℃ to below 200℃ and to improve the quality and grindability of the clinker.

Performance Features

Cooling machine, which can also be called rotary drum cooler, is able to fully suck the air that is used for cooling the materials as secondary circulation air, thus improving the thermal efficiency of the kiln, and in addition, it has the features of simple structure, high running rate and convenient operation and maintenance, so that is very suitable for small-sized cement plant.

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.
