With consistency of raw mix, process stability is easier to maintain, enabling production levels to be maximised, without risking equipment damage. Over-burning of clinker is also avoided, resulting in a more grindable product and lower electricity consumption in the cement mill, and fuel and energy inputs into a stable system are also lower.

These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components: CARBONATE COMPONENT (rich in calx) is contained in the raw mix in a quantity of 76-80%: Limestone. Mohs hardness is 1.8-3.0. The older the geological fraction, the firmer.
