Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism andCement clinker - Wikipedia,Portland cement clinker (abbreviated k in the European norms) is ground to a fine powder and used as the binder in many cement products. A little gypsum (less than 5 wt.%) must be added to avoid the flash setting of the tricalcium aluminate (C3A), the most reactive mineral phase (exothermic hydration reaction) in Portland clinker. It may also be combined with other active ingredients or cement additions to produce other types of cement including, following the European EN 197-1 standard: Efficiency of grinding stabilizers in cement clinker,,01/04/2013· Clinker grinding represents the most energetically demanding part of the production process and grinding stabilizers (very often known as “grinding activators”, “milling aids” or “grinding adds”, etc.) play a significant part in it. In spite of the fact that several new grinding stabilizers appear in the world patent literature each year, no significant developments in the technology have been apparent in this field for a long time and grinding
