Better and cheaper cement: Optimising the right clinker properties

When clinker cooler air is used for coal mill heating, the fine carryover dust can add large amounts of inert 'ash' to the ground coal. This can interfere with combustion and limit kiln output. The abrasive dust also accelerates equipment wear and makes burner pipe and snowmen buildups more likely.

This clinker is about 18" long and 8" wide. It was created by burning highash, low AFT bituminous coal. AFT is ash fusion temperature, or the temperature that the ash will become liquid and flow and stick together. It doesn't show real well in the photo, but there are lots of areas that look like melted glass.
