Effect of clinker composition on grindability -

1979-3-1  One disadvantage of excess liquid phase is the high resistance to grinding which the liquid phase imparts to the clinker and the resultant high energy consumption. The melt is responsible for difficult grinding clinker, because a structure is formed in which the silicates are embedded, which is comparable to basalt in structure (8).

The effects of excess sulfur on clinker properties - IEEE ...

2004-4-30  Abstract: 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.
