Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product …

The results showed that the HPGR-ball mill circuit achieved a 21% reduction in energy consumption over the existing SAG-ball mill circuit at the same P80 grind size of 160 mircons (μm). At a grind of 80% passing 75 μm, the HPGR-stirred mill circuit showed a 34% reduction in energy compared to the base case.

For ball mill modelling, the small pendulum device was used to test a particle size fraction of 4.75 to 5.6 mm. A fixed specific energy of the order of 1–2 kWh t −1 (depending on the particle density) from a pendulum input energy of 41.788 kg-cm was applied to individual particles in this size fraction.
