  • Energy Use of Fine Grinding in Mineral Processing

    Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizesThis 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 budgetminevik overflow ball mill sizes range from 5 ft x 8 ft with 75 HP to 30’ x 41’ and as much as 30,000 HP A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer • The rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/coke, and other materials for both wetGrinding / MCES – minevik official distributorMillpebs have been used as grinding media to achieve fine grinding in ball mills These are 5 to 12mm spherical or oblong cast steel pellets, charged into ball mills as a replacement of, or in addition to, balls While Millpebs can give significantly lower energy use when grinding to finer sizes, they also can lead to high finesEnergy Use of Fine Grinding in Mineral Processing
