The desired raw mix of crushed raw material and the additional components required for the type of cement, e.g. silica sand and iron ore, is prepared using metering devices. Roller grinding mills and ball mills grind the mixture to a fine powder at the same time as drying it, before it is conveyed to the raw meal silos for further homogenisation.
Normally in steel, chemical, or cement industries, different grades of limestone are used as a raw material feed (e.g. in cement making, the main requirement is that the magnesia and sulphur content of the limestone should be low and the CaO or CaCO 3 percentage should be as per the required specification of cement. In another …
