Breakthrough in Clinker Grinding

grinding seeks to reduce materials from roughly one meter cubes of blasted stone to a size where at least 80 percent of the raw material is less than 75 microns. Finish grinding of clinker and other cement ingredients reduces 25 mm clinker balls to particle sizes optimally ranging from 3 to 30 microns. The

Portland Cement Clinker - an overview | ScienceDirect Topics

Portland cement is a fine powder produced by grinding Portland cement clinker (more than 90%), a limited amount of gypsum (calcium sulphate dehydrate – CaSO4.2H2O, which controls the set time) and other minor constituents which can be used to vary the properties of the final cement. The standard Portland cement is often referred to as ...

Cement 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:

Cement mill - Wikipedia

A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m
