  • SAG Mill Grinding Circuit Design

    Such mills are common in South African operations mills are sometimes referred to as tube mills or ROM ball mills and are also operated both autogenously and semi-autogenously. Many of these mills operate at higher mill speeds (nominally 90 of critical speed) and often use "grid" liners to form an autogenous liner surface.

    Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho private communications).

  • Analysis of ball mill grinding operation using mill power

    Another important task associated with the ball mill grinding operation is to establish a sound basis for carrying out scale-up of ball mills based on laboratory or pilot scale test work. This requires studies related to the influence of mill diameter on production rate of particles of a desired size distribution.
