The working principle is that cement is removed from the mill before overgrinding has taken place. The cement is then separated into a fine fraction, which meets finished product requirements, and a coarse fraction which is returned to mill inlet. Recirculation factor, that is, the ratio of mill throughput to fresh feed is up to three.

The reaction degree of different fly ash in cement paste is observed in these curves. When raw fly ash is added, the insoluble residue is more than other samples. The reaction degree of raw fly ash is about 5% after 1 d, 21% after 28 d and 33% after 90 d. After grinded in the mill, the reaction rate of fly ash is faster to some extent.
