DR Congo mill expansion: add ball mill or screening first?

Today we run two crushing stages plus one ball mill at 800 t/day and want 1,200 t.
We suspect screening: the undersize runs coarse, mill feed is too big and throughput stalls.
Budget covers one stage only. If we add screening first, will the mill choke even more?

Start with a screening efficiency test. If undersize is more than 15% coarse, screens and spray water both need work, and the fix is cheap.

We expanded screening first and mill throughput rose 18%, but the feed bin was too small and we had to add a conveyor later. Count both.

Adjust mill liners and ball charge at the same time; screening alone will not lift output while the mill stays under-loaded.
