    Optimization of continuous ball mills used for finish

    10/12/2004· Furthermore, it has shown that a L/D ratio of about 3.0, which is a quite common value for cement mills, might be to high for a ball mill in a Combi-grinding plant. This was proven by the fact that there was no grinding progress observed in the last third of the total grinding path length. This finding was not effected by different ball charge filling ratios and different mill

    Optimization of continuous ball mills used for finish

    The optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio. On the basis of the present results and considerations, a specific optimisation of ball mills in semi-finish-grinding plants can be done.

    Cement grinding optimisation ScienceDirect

    01/11/2004· Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5–8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer than Portland, this figure would be even higher
