Cement Clinker Manufacturing Process with Reactions
The principal reaction of this stage is as follows: Ca2SiO4 + CaO → Ca3SiO5. The liquid formed both acts as a solvent of ion exchange between the solid phases and draws the reactant particles together by surface tension. The powdery or granular mixture quickly solidifies into spherical nodules of clinker.
