screen efficiency ball mill

screen efficiency ball mill

The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...

    Effect of Moisture on Screen Efficiency

    Jul 26, 2015 The objective is not spraying water on the screen, it is to dilute the feed to the screen. An alternative to trying to spray on water is to install a simple measured ‘water blade/fall’ at the front of the screen deck. This water addition point would replace most of the ball mill cyclone feed water. Screen-Efficiency
