Abstract

En el procedimiento y el aparato, se divide la corriente de gas en tres corrientes parciales de gas; la primera corriente parcial de gas transporta el material de molienda al espacio de molienda y de friccion del molino 26, mientras que la segunda corriente de gas se mueve alrededor del espacio de friccion del molino; la tercera corriente parcial de gas se conecta al lado de salida del molino y recibe material molido reducido y secado, transportado fuera del molino por las corrientes parciales primera y segunda de gas, a fin de transportarlo al separador.
