How Cement Is Made

The heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. After the clinker is cooled, cement plants grind it and mix it with small amounts of gypsum and limestone. Cement is so fine that 1 pound of cement contains 150 billion grains.

EP0726437A1 Oxygen lancing for production of cement

Oxygen (8) is lanced into the main combustion reaction of a cement kiln (2) to increase heat transfer to the clinker bed (3) and to increase clinker production. Oxygen is separately lanced along the floor (7), i.e. the lowest wall of the kiln (2), to delay mixing with the flame to provide deep staging. The deeply staged oxygen flow is adjusted frequently to control emissions and stabilize the

The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a superfine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
