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.

ment_draftMay05.pdf). Wet-process kilns are more energy intensive and can con-sume more than twice the amount used by dry-process kilns (Gartner 2004). All cement kilns in SA use the dry process. 4. Final grinding of the clinker together with inter-grinding with a small proportion of gypsum to produce Portland cement.
Two buildings, the cement mill and the pre-homogenisation tower in AGET Herakles, Lafarge plant in Volos, had to be upgraded to earthquakes. The mill building has a height of about 50 meters and its neighboring building, the pre-homogenisation about 66 meters, were made of reinforced concrete in the 70s and are separated by a joint.

therefore tracks the overall economic situation closely. The production of cement in the European Union stood at 172 million tonnes in 1995, equivalent to about 12% of world production. After mining, grinding and homogenisation of raw materials; the first step in cement
With this crude method, he laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine it will pass through a sieve capable of holding water.
cements. This can only be achieved if the plant designers have precise knowledge of the materials that will be used (raw materials and fuels). This is the basis for purposive selec-tion of the production process, including the blending, storage, homogenisation, grinding and analysis systems. As the first step, experienced geologists determine ...
