Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The European Cement Research Academy (ECRA) estimates that up to 70% of the power consumed in cement production is for material size reduction. Increasing the efficiency of particle size reduction could have a large impact on energy consumption in the ...

2. The limestone is combined with clay, iron ore and sand. It is then ground in a crusher and fed into. 3. Next, the fine powder is heated as it passes through the PreHeater Tower into a large kiln. In the kiln, the powder is heated to 1500oC. This creates a new product, called clinker, which resembles pellets about the size of marbles.

The grinding process differs depending on the pyroprocessing process used. The feed to the kiln is called "raw meal." Clinker is produced by pyroprocessing the raw meal. The raw meal is burned at high temperatures, first by calcination of the materials and then by clinkerization to produce clinker. Various kiln types have been used historically or are used around the world. Besides the ...
