The ball mills are in "closed circuit", meaning that the discharge is pumped to the classifying units (cyclones) and the particles will not pass to the next grinding stage until they are fine enough to be classified as such. The second stage grinding circuit (the pebble mill circuit) also consists of mills, pumps and cyclones.
