This residue from burning coal needs to be removed in order for a coal-fired boiler to function properly. If you have a coal-fired boiler, the formation of clinkers is not uncommon. Clinkers can occur if there's a kink in the process, whether you have a small coal stove, a whole-house coal-fired boiler or even an industrial-sized commercial boiler.

12. Working In case of continuously operated ball mill, the material to be ground is fed from the left through a 60° cone and the product is discharged through a 30° cone to the right. As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell.

Independent of the raw meal used, the different clinker phases were formed in three stages: 1. C2S, C3A and C4AF formation at ~900-1350 °C; 2. Clinker melt formation at ~1350-1400 °C; and 3. C3S formation at >1350 °C. The first temperature of clinker melt occurrence varied slightly depending on the type of raw meal used.

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. …
