This confirms that the grinding process of the ball mill follows the first-order kinetics, and the particle size decays exponentially with time. Similar observations were reported for dry and wet grinding of different mills such as the stirred mill and planetary ball mill [17, 20]. Download : Download high-res image (65KB)

The classifier delivered 33 T. of sand per hour. The total ball-mill feed was therefore 40.37 T. per hr. or 550 per cent, of the original feed. Two Stage Grinding. The object of these tests was to determine …

It can be summarised that for ball mills in Combi-grinding plants the optimal L/D ratio is clearly below 3.0. For coarse feed material about 2.7 seems to be appropriate and about 2.3 for finer feed. ... Further studies of ball and powder filling effects in ball milling.
