Raw Material Preparation Cement Plants and Kilns in

Preparation of cement raw materials Alite (approximately Ca 3 SiO 5) provides almost all the "early strength" (strength up to seven days of curing) of cement and a moderate amount of late (>7 days) strength Belite (approximately Ca 2 SiO 4) provides very little "early strength" and a large amount of late strengthSo it can be seen that these small compositional changes have a large effect

Raw Mill Feeding Cement Plant Optimization

In the value stream map of cement manufacturing the raw mill feeding is an intermediate activity between Prehomogenization and raw milling, and has not been discussed separately by most of the authors However, in my opinion it remains and must remain as of pivotal importance, so far as the quality assurance is considered
