After cooling and storage, the clinker is ground into a fine cement powder and gypsum is added, as a source of calcium sulphate, to improve the future setting behaviour of the cement. Cement clinker production places a high demand on natural resources and large amounts of CO 2 emissions are also generated from the energy needed to convert the

A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet process kiln but longer than a dry process kiln with a

Sintering: Sintering is the process of compacting and forming a solid mass of material by heat or pressure to the point of liquefaction without actually melting it. When the temperature inside the kiln reaches about 1300°C (the eutectic melting point of aluminate, ferrite and silicate), clinker

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.

The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the results obtained from a closedcircuit tube mill operating at

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.
