### Grinding Mills - an overview ScienceDirect Topics

Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However, even in open circuit, a coarse classifier such as a trommel attached to the mill, or a vibrating screen can be used. The oversize material is recycled either externally or internally. In internal recycling, the coarse material is conveyed by a reverse spiral or water jet back down the ...

25/08/2020 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.
