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 ...

A ball mill for limestone is a type of grinder used to grind materials into very fine powder for use in ceramics, paints, pyrotechnics, and mineral dressing processes. By revolving a cylinder filled with grinding balls, the ball mill grinds the material by causing the balls to fall back into the cylinder.
