The cyclone preheating system Phase IV: Calcination. The calcination is the core phase of the cement making dry process. The calcination of the preheated raw meal takes place in the rotary kiln of the cement plant. The rotary kiln is a huge rotating furnace in which the raw meal is heated up to 1450 ⁰C and turned to clinker.
Modelling and simulation studies were carried out at 26 cement clinker grinding circuits including tube mills, air separators and high pressure grinding rolls in 8 plants.
Cyclone preheaters are also called suspension preheaters. In the new dry process of cement manufacturing, the raw meal must be preheated in the preheater before entering the rotary kiln for calcining.The quality of the preheater in a cement plant directly affects the stability of calcining temperature and cement clinker quality in the kiln.

Dynamic separators are classified in three categories (*), the first, second and third generation.: In first generation separators, the air flow is generated by a fan within the body of the classifier. - In second generation, the air flow is generated by an external fan and there are cyclones.
The cement content of the initial mixture (MIX) increased with the reduction of the fraction size (Fig. 6), from the 500–1000 μm towards the 125–250 μm range. In fact, the comminution process tends to accumulate more cement in the finer fractions, as has also been reported by other authors (Angulo et al., 2009; Krour et al., 2020).

Changing the separator to a high efficiency type brings about better residue value (on 45 micron) for the same Blaine. Alternatively, the cement can be ground to a lower Blaine with the same residue, which determines the strength of cement. In most cases the layout permits replacing the separator to a high efficiency type.
