Outotec stirred mills are part of the Planet Positive product portfolio, which apply the mill input energy to liberate mineral in a sustainable manner. By adding Outotec classification, pumping and automation technologies, the fine grinding solution aims to take sustainability to another level by optimizing the usage of energy, water, grinding media and consumables.

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes.This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget.
