The crushed limestone and aggregates such as sand, clay and ironstone are blended together in a raw mill to a particle size of 90 micrometres, producing “kiln feed”
Cement Plant: The Manufacturing Process

1Limestone (CaCO3) is taken from a quarry

The limestone is fed into a crusher and then stored until needed
The clinker is mixed with additives, such as gypsum, and then ground in a cement mill, which creates cement
The cement is then packed and distributed to consumers
The kiln feed is blasted in a cement kiln at a temperature of 1450oC, causing clinkering to occur (small balls of up to 25mm diameter)
