Cement Clinker Production - an overview ScienceDirect

Cement kiln dust is a by-product of cement clinker production, and has about 35 wt% of CaO and 2 wt% of MgO. Therefore, cement kiln dust has a high CO 2 storage capacity between 191 and 256 kg CO 2 /tonne of cement kiln dust. 11 Another source of Ca-based industrial waste is the paper industry.

Clinkerization - Cement Plant Optimization

Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.
