Calculation of The Formation Process of Clinker in | PDF
This document summarizes the process of clinker formation inside a rotary cement kiln. It discusses how the selection of raw materials that are either more difficult or easier to burn affects the heat required for clinker formation and the coating thickness. Materials that are more difficult to burn require more heat for clinker formation and result in a weaker, less stable coating. …
