Modern dry process cement plants use preheater towers such as shown in Figure bellow to pre-process the kiln feed and thus save energy. the temperature rises, converting the calcium and silicon oxides into calcium silicates – cement's primary constituent.

Cement Manufacturing Process: What is Cement made of.

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Mixing of Raw materials in wash mill with 35 to 50% water. Materials exiting the mill are called "slurry" and have flow-ability characteristics.

Cement Production - The Concrete Portal

The total power consumption in this process is also higher and the output lower than in the dry process. However, blending is much easier in a wet state. Most modern plants opt for the dry process with preheaters and precalciners.

The Cement Sustainability Initiative (CSI) - Cement Production

Cement production is either "wet" or "dry", depending on the water content of the material feedstock. The wet process was the original rotary kiln process developed at a time when material handing of slurries was more developed than those of dry powders.

Production Process | CEMEX Philippines

Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.
