chemical reactions in cement manufacturing process

The effective reactions here are:Si2Al2O5(OH)2→ 2 SiO2 + Al2O3 + 2 H2O (vapor) KAlSi3O8 (orthoclase) + 0.5SO2 + 0.25 O2 → 3 SiO2 + 0.5 Al2O3 + 0.5 K2SO4. Dolomite decomposition: The magnesia in the raw-mix exists mainly as dolomite, CaMg (CO 3) 2, but also as silicate or in carbonate form. Dolomite reacts as follows:
