Grinding and homogenization. The grinding process takes place in a raw mill to reduce the particle size of the components to a typical value of 10-15 % residue on a 90 um sieve. The output of the grinding process – called 'raw meal' – is transferred to a homogenization silo before the clinker manufacturing process.

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 cement is now ready for transport to ready-mix ...
