- Wet Process Of Manufacturing Cement
The main difference between the dry process and wet process of cement manufacture is the way in which the raw materials are prepared before they are fed into the kiln.. In the dry process, the raw materials are ground and dried into a powder, which is then mixed and fed into the kiln. The raw materials are heated to a temperature that …

Cement plants have used new grinding equipment, dry-process instead of the wet-process kiln, modern clinker kilns, and multi-stage preheaters that can save energy [1]. The use of blends with renewable fuel and fossil fuel [ 2 ] or the use of solar calcination reactors [ 3 ] can reduce emissions and save energy in cement manufacturing.

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.
