G. Habert, in Ecoefficient Construction and Building Materials, 2014. Introduction. Cement production has undergone tremendous developments since its beginnings some 2,000 years ago. While the use of cement in concrete has a very long history (Malinowsky, 1991), the industrial production of cements started in the middle of the 19 th century, first with shaft kilns, which were later
Cement Production: Raw Meal Production in Steps Perfectly mixed, accurately fed without pulsation, and precisely weighed. The key word is quality! And this quality is achieved during cement production with exactly matched process steps. In the first stage, the raw meal is produced, as described below.

· Cement raw materials are received with an initial moisture content varying from 1 to more than 50 percent. If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding. Drying alone can be accomplished in impact dryers, drum dryers, paddleequipped rapid dryers, air separators, or autogenous mills. However, drying can also be

· For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements. Before transportation of raw materials to the cement plant, large size rocks are crushed into smaller size rocks with the help of crusher at quarry. Crusher reduces the size of large rocks to the size of gravels. Cement Manufacturing Process Phase II
At the end of a line or section there should be a checker to inspect all the parts before they leave the section. The inspections should be effective in identifying all defects in a garment. The checkers should have their forms filled correctly. A good source of information to determine the quality performance of the section is the point of inspection. The section supervisor should check

consumption and raw material calcination dropped 24%, from 610 lb C/ton of cement ( tC/tonne) to 469 lb C/ton cement ( tC/tonne). Despite the historic progress, there is ample room for energy efficiency improvement. The share of wetprocess plants decreased from 60% in 1970 to about 7% of clinker production in 2010 in the The remaining plants suggest the existence of a
