Cement
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

Once the dry ingredients are mixed post crushing, a small amount of water is added to the mix to supplement the moisture content to about 14%. Consequently, the addition of water propels the cohesion process and small lumps begin to form. The cake-like lumps are dried and fed to a rotary kiln, where they are subjected to a very high …
