Cement Clinker Grinding Aids
A variety of additives have been shown to have grinding aid characteristics for grinding cement clinker. Typical among these are amines, organosilicones, glycols, resins, cod oil, kojic acid, carbon blacks, wool grease, calcium sulfate, urea, asphaltenes, etc. Figure 4-26 shows a typical comparison between the grinding of cement clinker …
CLINKER GRINDING IN CEMENT PRODUCTION
Value KS K = 92 % indicates that clinker is medium grinded, KS K > 92% – easy to grind, KS K <92% – hard to grind. The lower value KS K, the larger the clinker. Typical KS K values in Portland cement clinker are 0.8-0.98, or 80-98%. The value KS K of ordinary Portland cement is 90-95% and 95-98% of high strength Portland cement.

Clinker grinding technology in cement manufacturing
Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …

What is Clinker? The Relationship Between Clinker Phases and Grinding …
Raw meal powder enters into the furnace system, it transitions into the melt phase, and clinker is obtained once furnace and cooling reactions are completed. The first melt phase is formed at 1260°C-1310°C. Clinker melt's rate increases as the temperature rises and it reaches up to 20-30% in weight at 1450°C depending on the chemical compound.
