The device (10) for supplying cooling gas is configured in an annular manner about the entire circumference of the vertical airflow mill (1). Inlet (21) and outlet openings (24) for the cooling gas have an adapted surface which allows an equalization of the inflow cooling air into an increasing airflow/milling particle mixture.
