Dec 18, 2013 Fine grinding, to P80 sizes as low as 7 m, 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 mills energy budget.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting .. A rotating drum causes friction and attrition between steel rods and ore . Rod mills are less common than ball mills for grinding minerals. Contact US grinding ball mill ore mineral

The Mikro UMP Attrition Mill is high speed cutting mill designed for the fine size reduction of plastics, polymers and fibrous materials that do not respond well to other forms of impact milling. It is designed to grind heat sensitive and soft materials without liquid nitrogen or conditioned air.
A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power. The torque required to turn the mill is given by Torque T Mcgdc T f 8.9 Where Mc is the total mass of the charge in the mill and Tf is the torque required to overcome friction. Power 2 NT 8.10
