description The invention relates to a two-stage grinding circuit consisting mainly of a first grinding stage (1), which comprises a vertical roller mill (10) having a grinding disk (11), at least one grinding roller (12) interacting with the grinding disk (11) and a first dynamic separator (13), the first dynamic separator (13) comprising a fine material outlet (15) for discharging fine material (5) and a grit return (16) for returning grits (8) to the grinding disk (11), and a second grinding stage (2), which has a second mill (20), which is formed by a stirred ball mill or a ball mill, the second mill (20) comprising an inlet (21) and an outlet (22). Furthermore, a grit extraction device (18) is provided for extracting part of the grits (8), the grit extraction device being connected to the grit return (16) and being connected to the inlet (21) of the second mill (20).
