In the article attention is paid to improving the efficiency of production of fine powders, in particular Portland cement clinker. The questions of Portland cement clinker grinding in closed circuit ball mills. Noted that the main task of modeling the grinding process is predicting the granulometric composition of the finished product taking into The dry process of cement manufacturing utilizes 3.40 GJ of specific energy per ton of clinker production, while the wet process utilizes 5.29 GJ/t. It has been reported that the specific energy consumption value for many countries is less than 2.95 GJ per ton of clinker, while the minimum value in India is 3.06 GJ ( Madlool et al., 2011,Review on energy conservation and emission reduction

Advanced Process Control for Clinker Rotary Kiln and Grate Cooler

The cement industry includes energy-intensive processes, e.g., clinker rotary kilns and clinker grate coolers. Clinker is obtained through chemical and physical reactions in a rotary kiln from raw meal; these reactions also involve combustion processes. The grate cooler is located downstream of the clinker rotary kiln with the purpose of 3000°F in the kiln. Rotary kilns are divided into two groups, dry-process and wet-process, depending on how the raw materials are prepared. In wet-process kilns, raw materials are fed into the kiln as a slurry with a moisture content of 30 to 40 percent. To evaporate the water contained in the feedstock, a wet-processAVAILABLE AND EMERGING TECHNOLOGIES FOR REDUCING GREENHOUSE GAS

Finally, a study of clinker's grindability enabled us to evaluate the probability of grinding of these samples. In all cases, the best clinker is the one that has a vintage's fineness close to 13making cement by the chemical reaction between the components of the ground mixture. This chemical reaction occurs at high temperature in a rotary kiln, grinding the cement clinker nodules to 100% passing 90 μm in a dry circuit.

However, a low clinker fines content is also important for the best process and quality performance. Fine clinker can contribute to red rivers and other cooling problems, but there are other impacts. Clinker dust carried back into the kiln interferes with heat transfer from the flame, slows nodule growth and encourages even more dust
