201731;After mining the ore, mills use small steel balls to grind it smaller for further processing. To assist with loading and unloading of these steel balls, they use a kibble system.
The charge filling in a ball mill is about 30–45% of the internal volume of the mill, about 40% of this being void space. As discussed in Section 7.2.2, the reason is the power draw passes

2017213;In pebble and ball mills quite often charge volumes close to 50 % are used. In a pebble mill the pebble consumption ranges from 3—15 %
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the
Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is
