periscopical clinker cooler camera (Fig.6). From start to finish, pyro-processing in a rotary kiln operation can be monitored and process controls implemented. Integrated into an expert system (e.g. CEMAT-KCS) the imaging pyrometer or clinker cooler scanner is an essential tool for process optimization.
Early systems used rotary coolers, which were rotating cylinders similar to the kiln, into which the hot clinker dropped. The combustion air was drawn up through the cooler as the clinker moved down, cascading through the air stream. In the 1920s, satellite coolers became common and remained in …

Clinker cooler efficiencies The cooler efficiency plays a key role in which its function is recovery heat from the hot clinkers and pre-heating the air that is used for combustion as secondary air for the rotary kiln and tertiary air for calciner.
Industrial Clinker Cooler is extensively used to cool the clinker and extracted heat from hot clinker is supplied at secondary and tertiary air to kiln. Acknowledged for its optimum specific grate load, this ensures lower heat consumption.

COOLER TECHNOLOGY I n a cement plant, clinker is discharged from a rotary kiln into a clinker cooler to cool down from 1350°C to around 100°C. During this operation, cooling air from under the grate compartment of the clinker cooler follows a path throughout the grate plates to the discharged clinker and some portion of the cooling air is used as

The Air-Quenching shaking grate Clinker Cooler was developed more than 20 years ago as an improved heat recuperating cooler for use with rotary kilns. It was designed to air quench and cool large quantities of hot clinker rapidly, and to recover and return to the kiln a major portion of the heat from the clinker.
