Multistage cyclone preheaters and precalciners in a cement plant. ... Raw meal from the preheater (not shown in Figure 3.2.5) is fed into the bottom of the precalciner and is conveyed through the precalciner to the lowest stage cyclone by the precalciner gases. During this time, fuel combustion and heat transfer to the raw material are occurring.
