A method for producing cement

The present invention provides a method for producing cement, even when the amount of P2O5 in the cement raw material changes, the amount of P2O5 can be maintained in the cement clinker within a predetermined range. In the atmosphere of the kiln at a high temperature above 1400 deg.] C to maintain the interior of the (1), from the inlet end (2) into the interior of the cement raw material into the kiln provided in the front (4) of the main burner (5) Flame a method for producing cement kiln front (4) side in the feeding and firing in the cement clinker produced, will change the amount of the amount of the change amount P2O5 P2O5 amount of the cement material or the above-described manufacturing cement clinker comprising compensating the amount of dry sludge into (1) the cement kiln, thereby controlling the amount of P2O5 included in the cement clinker is in the range of 0.3 to 1.0 wt%.
