2016-1-20 · Clinkering is the primary step in the cement manufacturing process. The function of the kiln in the cement industry is to first convert limestone into lime, then react it with silica, aluminum oxide, and ferric oxide to form clinker compounds: C 3 S, C 2 S, C 3 A, and C 4 AF. The kiln is the heart of this production process.
