Ball mill definition: a grinding mill in which the material to be ground is tumbled in a drum with heavy balls of iron, steel, or stone.. See examples of BALL MILL used in a sentence.
This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general. Planetary ball mills with higher energy input and a speed ratio of 1:-2.5 or even 1:-3 are mainly used for mechanochemical applications.
Additionally, in ball mills grinding is primarily through cascading not cataracting (compared to an AG.SAG) so the slurry pool is not a factor unless density is high, which leads to viscosity issues. ... (I assume) an overflow mill so by definition will be full. Adjusting the ball charge to meet the capacity demand will ensure that it is not ...
