Cement - Coursework Example First step encompasses preparation of material to their required size and condition. Mainly, this is size reduction of materials, which are bulky in size and cannot fit well in the rotary kiln besides ensuring intimate reaction of varied chemical components (ZKG, 2010). This process is raw milling mostly taking place in the field before transportation of lime (ZKG, 2010). Once materials arrive in the factory, mixing or blending of varied components takes place. This is to ensure uniform and intimate reaction of materials once they are in the kiln, which is always at high temperatures. However, these temperatures usually vary significantly in diverse sections. These include dehydration (- 4500C), Calcination (4500C to 9000C), solid-state reaction (9000 – to 13000C), clinkering section (13000C to 15500C) and finally cooling zone (Thomas & Jennings, 2008).  After formation and cooling of clinker in silo, milling commences with addition of other essential additives whose role is to ensure cement attains its required condition before stored in silosg (ZKG, 2010). Milling entails feeding the clinker into a four-chamber or cemernt mill coupled with addition of gypsum and other components to produce a very fine powder, which is cement (Taylor et al. 2008). After milling, the fine powder based on materials may stay in the silo for sometime before packaging takes place. This is to allow final residue process take places effectively whereby afterwards packaging or bagging takes place before kept in warehouses.
