The effects of excess sulfur on clinker properties IEEE

Apr 30, 2004Abstract: It has long been known that excess sulfur in clinker can lead to operational changes in the pyro-processing system. Excess sulfur will also create changes in the finish grinding system. Not only can the sulfur content change the clinker size distribution, but changes in clinker chemistry can have effects on cement quality.

The cooled clinker is a kind of granular material with different particle sizes. They will be ground in the grinding mill to reach the qualified fineness of cement products. 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.

Tackling clinker-reducing conditions GCP Applied

Reducing conditions can result from insufficient air, excess fuel use, low feed rate, or inadequate grinding of the fuel as well as carbonaceous content in the raw feed. Reducing conditions also increase volatilization of sulfur, which risks built-ups in the kiln preheater and subsequently reduced alkali sulfate in the clinker.
