In a mill drying plant with a roller grinding mill and preferably in a cement production plant operated in compound with a clinker burning process and having a kiln fan and a fan downstream of a filter, a mill fan is connected upstream of the roller grinding mill as a further fan. This makes it possible to overcome the resistance of the roller grinding mill blade ring and to force the pressure zero point into the roller grinding mill, so that there is a low vacuum above the blade ring in the milling and classifying chamber and in the filter.
