Preheaters are used industrial dry kiln cement production plants to heat the raw mix and drive off carbon dioxide and water before it is fed into the kiln. An analytical model of a generalized four-stage suspension cyclone preheater system is presented. This model was used to study the influence of waste preheater gas and dust bypass systems on preheater performance and efficiency. As the ...
