Manufacture of Portland cement

The cool clinker produced by wet or dry process which is characteristically black and hard is interground with gypsum CaSO R4 R.2H R 2 R O in order to prevent flash settingof the cement and to facilitate the grinding process The grinding is done in a ball mill The cement discharged by the mill is passed through a separator fine particles

Avoiding Clinker Formation in Thermal Power Plant Boilers

17.08.2010  Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss Removal of clinkers from the water wall is difficult thus requires pneumatic hammering Low quality coal having less gross calorific value high mineral content high ash content and the over firing of molten slag are causes of clinker formation.
