Application of Accurate Ball-Load-Addition Method in Grinding Production of some Tailings

Grinding fitness caused by the failure of the steel ball filling rate, inappropriate steel ball matching, large steel ball size, etc. cannot meet follow-up flotation requirements. In order to optimize the ball grinding process, enhance the single separation degree of minerals and separation index, the steel ball diameter, steel ball matching and required additional balls of the mill are calculated with theoretical of ball radius formula and accurate filling ball method.
