The invention relates to a process for producing cement with milling of cement clinker and sulphate carrier, where the sulphate carrier is preferably gypsum. According to the invention, it is proposed that the cement clinker and the gypsum be milled separately from one another in a high-pressure roller mill and/or vertical mill and only the sulphate carrier is heated in the circuit. In this way, only the gypsum is heated and dehydrated and up to 95% of the heat for converting gypsum into hemihydrate is saved. |
