ball mill grinding media sizing

An innovative approach for determining the grinding
2021年1月22日 An novel approach for determining grinding media system of ball mill was proposed. • The optimum media ball size of three size fraction samples were obtained. • The media size ratio was ascertained as φ 50 mm: φ 40 mm: φ 30 mm = 28%: 28%: 44%. •

Energy Use of Fine Grinding in Mineral Processing
2013年12月18日 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
