optimisation of the ball charge in mills for cement grinding

Operation and Elements of a ClosedCircuit Ball Mill System.Cement ball millstypically have twogrinding chambers. The firstchamberis filled with larger diametergrindingmedia and lined with lifting liners. The firstchamber coarse-grindsthe feed material and prepares it for the second chamber. The second chamber is thefine grinding chamber.

    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 theball chargefilling ratio and particularly on the L/D ratio. On the basis of the present results and considerations, a specificoptimisationofball millsin semi-finish-grindingplants can be done.

    Jul 31, 2014· 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.
