Cement | SpringerLink

Cement is produced by a high-temperature (about 1500 °C) reaction in a rotary kiln of carefully proportioned and blended ratios of lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3).The production of cement is a chemical process requiring an accurate blend of the previously cited four key organic oxides and the …

Everything you need to know about clinker/cement Grinding

1) alite size, as before. 2) C2S content, as before. 3) grinding aid. Cost 0.6-1.2 €/t, usage 150-400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor. Increasing the amount of grinding aid will make the cement easier to grind. Hard burning = hard grinding.

Drying of raw materials

Generally in the dry production process, the moisture content of cement raw materials requires drying before grinding. The moisture content of limestone is up to approximately 8 %, that of marl is up to 15 0/o, and clay has a moisture content of up to 20 %; wet granulated high furnace slag contains up to 35 0/o. Coal also usually requires drying.
