>What Causes Clinkers in Coal-Fired Boilers? | Hunker
Clinkers, also known as slag, are the parts of the coal that won't burn. The act of burning coal at high heat causes the minerals to melt instead of burn, resulting in ashes that often contain hard lumps. These lavalike lumps then meld together to form even larger lumps that, if not removed, will make the boiler much less efficient.
>Cement Clinker Calcination in Cement Production Process ...
The cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its solidification speed will not be too fast.

A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
