CO2 Emissions Profile of the U.S. Cement Industry

In the “wet” process, the ground materials are first mixed with water to form a slurry before being fed into the kiln. The use of the dry process for cement production has increased significantly in the last couple of decades (Figure 1), partially due to the lower fuel requirements for the dry process (discussed further below). In 1975, dry

Cement Manufacturing Process: How the Cement is Made?

All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.
