cement mill circuit diagram pdf

In thediagramabove of a precalciner kiln, raw meal passes down the preheater tower while hot gases rise up, heating the raw meal. At 'A,' the raw meal largely decarbonates; at 'B,' the temperature is 1000 C - 1200 C and intermediate compounds are forming and at 'C,' the burning zone, clinker nodules and the final clinker minerals form.

    In an opencircuitsystem, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closedcircuitsystem, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of thecement.
