CEMENT MILL OPTIMIZATION

I HAVE A POLYSIUS BALL MILL WITH CAPACITY 110 TPH. NORMALLY I GET BLAINE AT MILL OUTLET AROUND 200 WHILE MY PRODUCT BLAINE TARGET IS 400 . SEPARATOR REJECT BALINE IS AROUND 90 . 

I THINK I SHOULD PUT MORE SMALLER GRINDING MEDIA IN II CHAMBER TO INCREASE THE FINENESS AT MILL OUTLET TO OBTAIN 230 TO 240 BLAINE. 

SHOULD I INCREASE 17 MM MEDIA % IN II CHAMBER ?

THIS WILL REDUCE THE RECIRCULATION WHICH IS AROUND 220 AT 100 TPH OF PRODUCT & HENCE I SHALL BE ABLE TO INCREASE OUTPUT ALSO WITH INCREASE IN PRODUCT BLAINE.

AT PRESENT I AM GETTING 370 TO 380 BLAINE IN PRODUCT.

MY FILLING % IN II CHAMBER IS AROUND 24% .

PLEASE DO SUGGEST.
