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.

What is the manufacturing process of Portland Cement?
The materials, without the gypsum, are proportioned to produce a mixture with the desired chemical composition and then ground and blended by one of two processes – dry process or wet process. The materials are then fed through a kiln at 2,600º F to produce grayish-black pellets known as clinker.

Cement Production - an overview ScienceDirect Topics
The production of cement is either through the wet or dry process with the dry process as the preferred option because of the lower energy intensity. Cement production accounts for about 5% of total anthropogenic emissions (IFC, 2017). Cement-based structures constitute the largest surface area of all man-made structures (Odigure, 2009).
