Grinding Mills also know as Semi-Autogenous SAG, Ball or Regrind Mills are used in the primary or early stages of pulverizing the ore in the process plant. This initial grind of the ore is typically completed in two or three stages. The mills are driven by large high horsepower electrical motors and the outer shell of the mill is lined or ...
