Plant for the selective production of cement clinker for gray or white cement

摘要

The invention relates to a plant for the production of cement clinker for gray or white cement, comprising a rotary kiln (15) for sintering calcareous and silicate-containing raw meal (35) and optionally other oxides to cement clinker (45), wherein a burner lance (25) on Drehrohrofenkopf (25). 40) of the rotary kiln (15) is present for generating the necessary sintering temperature in the rotary kiln (15). According to the invention, it is provided that the burner lance (25) is movably mounted outside the rotary kiln housing (10) whereby the depth at which the burner lance (25) extends into the rotary kiln (15), is variable, and the rotary kiln (15) opens into a clinker cooler (20), below a discharge opening of the rotary kiln (15) a flap (50 is present, which releases a crusher (55) or covers , wherein the flap (50) in the open state, the cement clinker (45) discharged from the rotary kiln (15) on the crusher (55) passes, and in the closed The condition is that the cement clinker (45) cast off from the rotary kiln (15) passes into the clinker cooler (20). The plant can optionally produce cement clinker for white cement or cement clinker for Portland cement.
