Portland Cement Clinker an overview ScienceDirect
The sintering of Portland cement clinker is simply called “twice grinding and once sintering”, that is, grinding the cement with cement raw material; sintering the calcined part of the raw material into clinker; grinding the clinker with a limited amount of gypsum Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality Having a high percentage of coarse clinker can be Clinker size and cement grinding GCP Applied
Experimental study of clinker grinding in a ball mill and
The use of highpressure grinding rolls (HPGR) prior to ball mills has become a common practice in cement clinker grinding due to significant energy savings 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 highchromium steel The smaller grades are occasionally cylindrical ("pebs") rathCement mill
Cement clinker
Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall Organic compounds are also often added as grinding aids to avoid powder agglomeration Triethanolamine (TEA) is commonly used at 01 wt % and has proved to be very effective OtheThis diaphragm retains the grinding media in the second chamber and allows the discharge of finely ground material Closed Circuit Ball Mill System Clinker, Optimization of Cement Grinding Operation in Ball Mills
