Rod Mill or Grate Discharge Ball Mill ?
After the mill there would be a screen with 1mm opening, fines to spirals, coarse back to the mill. I used rod mills for such a coarse grind, but the handling of the rods is not as easy as if you use balls. So the question came up what a grate discharge ball mill would do here. I never used one.

Overflow vs. Grate Discharge Ball Mills: What's the Difference?
Overflow ball mills are designed so that the ground product overflows out of the mill. The overflow expels the ground material because of the slurry flow out of the mill. On the other hand, grate discharge ball mills have a grate wall at the discharge end, which holds the larger particles while the fine slurry is allowed to pass through.

Slurry flow in mills: grate-only discharge mechanism (Part-1)
Discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.
