The major components of the ball mill include a shell that is hollow and is suspended on its axis to bring about rotation. The axis of the shell can be suspended horizontally or at an angle to the horizontal.
Linked to the ball mill circuits will be two gravity gold recovery plants. A proportion of the ball mill discharge will be pumped to the two gravity gold circuits comprising scalping screens and centrifugal gravity concentrators.
mill. As such primary ball mills should be designed with the rod mill work index and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen Verret & Williams 2006). On
The grinding ball mills are equipments present in mining plants being important in the ore comminution circuits. Depending on numerous factors such as for example inappropriate design manufacturing overloads poor maintenance and inadequate operating procedures flaws are developed in the structural components of this equipment.
