• Cement Kilns: Precalciner kilns

  The proportion of fuel that can be efficiently burned in the calciner rises to about 70% (for ordinary blended rawmix feeds) The degree of calcination of feed entering the kiln rises to around 90-95%, and this defines the 70% fuel limit - any more fuel will risk the formation of clinker in the preheater, and this must be avoided at all costs...
