The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw ...

Refining sugar. The 'raw' sugar from the mill arrives at the refinery where it is mixed with hot syrup to soften the hard molasses coating on the outside of the sugar. Once mixed the syrup is put through a centrifuge which removes 50% of the colour from the raw sugar and is then melted into a liquor. The liquor undergoes further clarification ...

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect …
