circuit of vertical roller mill

  • Deniz Altun Doctor of Philosophy Hacettepe University, Ankara

    This paper presents the results of component modelling work performed around a closedcircuit cement grinding operation. In this context, the ball mill and the air classifier were modelled by applying perfect mixing and efficiency curve approaches, respectively. The studies implied that the shape of the efficiency curve
