how to increase mill grinding rate

The Mill Filling Rate Is the Foundation of Efficient Grinding

Jan 5, 2021If the mill manufacturer recommends filling the mill at 30%, the calculation of the loading tonnage shall be carried out using the minimum mill capacity. Keep 30% of drum filling with grinding balls, but not more than the previously calculated tonnage. The main rule is not to exceed this value, regardless of the volume of the inner mill drum.

Energy Use of Fine Grinding in Mineral Processing | SpringerLink

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. Overall energy use and media ...
