Cement Grinding - Raw Material Drying-Grinding

Lime (CaO) : This is the important ingredients of cement and its proportion is to be carefully maintained. The lime in excess makes the cements unsound and causes the cements to expand and disintegrate. On the other hand, if lime is in deficiency, the strength of cement is decreased and it causes the cement to set quickly.These materials include various raw materials, fuels, clinkers, mixtures and gypsum.
