Impact of the grinding process on the granulometric properties of triclinic alite

Four major clinker minerals, alite, belite, tricalcium aluminate and tetracalcium aluminate ferrite are crucial for cement properties. This work deals with alite as the most important clinker minerals. Alite is affected by the milling process technology more than other clinker minerals. It contains micro-cracks, which are formed during fast cooling, and is therefore less resistant to grinding than other clinker minerals. The paper deals with the influence of length and the technology of the milling process in 3 types of laboratory mills on the particle size and distribution, agglomeration and the change of the grain shape of the synthetically prepared triclinic alite.
