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
There are 76 cement kilns in operation, of which 40 are permitted to use alternate fuels such as tires, waste oil, waste wood, and so forth.

Alite has a CaSi ratio of 31 and C-S-H has a CaSi ratio of approximately 21, so excess lime is available to produce CH. AFm and AFt phases these are two groups of minerals that occur in cement, and elsewhere. One of the most common AFm phases in hydrated cement is monosulfate and by far the most common AFt phase is ettringite.
3 In the raw mill, the material chunks are ground finer to allow high-quality blending. As the raw mill is one of the biggest energy consumers in the cement process, it is important to adjust the grinding plant in order to minimize energy losses. 4 It is essential to use a process automation system to optimize the mill process, which in turn mini-
