WhatsApp: +86 18838072829The 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.
