The Process for Making Portland Cement Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, sandstone, marl, shale, iron, clay, and fly ash.

Dry process. In the dry process, the raw materials are dried in a combined drying and grinding plant to reduce the moisture content below 1%. The materials are ground in either a ball or a roller mill with drying of the materials being achieved by sweeping the mill with the exhaust gases from the kiln.
Kiln Processing. As raw meal tumbles through the kiln, it becomes partially molten, causing molecular reactions that result in the formation of new minerals with special hydraulic properties that, once ground, react with water to form a hard mass—the distinguishing characteristic of cement. The white hot substance that exits the kiln,...
Basically, cement is produced in two steps: first, clinker is produced from raw materials. In the second step cement is produced from cement clinker. The first step can be a dry, wet, semidry or semiwet process according to the state of the raw material. The cement manufacturing process is .

PrePour Steps to Speed Up the Drying Process. However, the more water present in the initial mix, the more water must evaporate out of the slab. Another option is to add "selfdesiccation" agents to the concrete mixture. Adding a higher ratio of cementitious material to the mix does bind more water into the paste of the concrete,...
Lafarge Ravena Cement Plant A modern day cementmaking process reaps real rewards. Lafarge Building Materials, Inc. (Lafarge) proposes to modernize and expand its existing Ravena Cement Plant by constructing a stateoftheart facility that is more economically and environmentally sustainable.
Cement manufacturing process. Evolution of the cement Process • Wet process easiest to control chemistry better for moist raw materials. • Wet process high fuel requirements fuel needed to evaporate 30+% slurry water. • Dry process kilns less fuel requirements • Preheater/Precalciner further enhance fuel efficiency allow for high production rates.
The burning process. Such a kiln is typically about 180 m long and 6 m in diameter, has a downward slope of 34%, and rotates at 12 revolutions per minute. (After Mindess and Young, Fig. ) Figure 32: Diagram of the reactions occurring in a typical dry process cement kiln without a preheater.
