    Tumbling ball mills are a common comminution device in the mineral industry processing, wherein the particle size reduction is performed by action of the grinding media. Different forms of transverse motion in a rotating cylinder have been studied by many researchers. The aim of this paper was to study the transitional phenomena between cascading, cataracting and centrifuging motion.

  • 3D simulation of charge motion in tumbling …

    The dynamics of charge motion in tumbling mills has been a challenging problem both experimentally and theoretically. The harsh environment within the mill precluded sophisticated sensors. On the other hand, first principle modeling of charge motion was only marginally successful since the motion involves hundreds of bodies colliding with each other.

    According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills. In tumbling mills, the mill shell is rotated and motion is imparted to the charge via the mill shell. The grinding medium may be steel rods, balls, or rock itself.
