particle distribution in cement ball mill

Influence of particle morphology of ground fly ash on the
The fluidity of cement paste and the strength of cement mortar are tested to study the relation of spherical destruction and fluidity and strength The results show that the spherical destruction of ground fly ash in a ball mill is more than 80 and that in a vertical mill with a separation system is only 11.9 .
