This assumes that a crusher would provide this energy. However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (i.e., the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from Eq.
For energy efficiency, it is normally recommended that the secondary crusher is preceded by a screen that separates the fines and passes them directly into the tertiary crushing circuit. The tertiary crushing step is usually operated in closed circuit with a screen aperture size typically in the range 9–12 mm.
