raw material size for cement production

Lime Component Limestone: Common forms of calcium carbonate used asraw material for cementmanufacturing are limestone and chalk.Limestone is of predominently fine grained cryistalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or iron compounds, which influnces its colour.

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 of76-80%: Limestone. Mohs hardness is 1.8-3.0. The older the geological fraction, the firmer.
