Grinding efficiency. Ball mill by A.Sen Medium

Mat circulating load factor is computed for raw-mill and cement-mill at a sep efficiency of 90 and 70% for target residue 16 and 1% respectively on 90 microns sieve. This is observed, to maintain an acceptable circulating load factor between 1.5 to 2.0, a target mill discharge residue on 90 microns sieve would be 40–50 % for raw grinding and 10–20 % for cement grinding.
