Kiln and Cooler –Control and Optimisation. By Dr Y C Naidu Cement Plant Typical View Basics of Kiln and Cooler • Kiln for pyroprocessing of raw material to make clinker • Technology development from wet – semiwet/semi dry- preheater kilns- precalciner kilns • Cooler to cool clinker for further material conveying and also recuperation of heat
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
The criteria for bypass operation are complex depending upon input concentrations, stoichiometric balance between alkalis and sulphur, intrinsic volatility, kiln retention (the heat loading and retention time is shorter in precalciner kilns), and upon cement specification (Farag & Kamel; ZKG; 10/1994, pg 586).
