Cement : Manufacture, Chemical Composition, Heat of

2015-1-13  Cement In the most general sense of the word, a cement is a binder, a substance that sets and hardens independently, and can bind other materials together. Cement used in construction is characterized as hydraulic or non-hydraulic. Hydraulic cements (e.g., Portland cement) harden because of hydration, chemical reactions

11.6 Portland Cement Manufacturing

1971-8-17  In the wet process, water is added to the raw mill during the grinding of the raw materials inball or tube mills, thereby producing a pumpable slurry, or slip, of approximately 65 percent solids.The slurry is agitated, blended, and stored in various kinds and sizes of cylindrical tanks or slurrybasins until it is fed to the pyroprocessing system.

Ball Mills - an overview ScienceDirect Topics

Air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling. Grinding is an energy intensive process and grinding more finely than necessary wastes energy. Cement consists of clinker, gypsum and other components mostly more easily ground than clinker.
