Learn MoreVertical cement mill has high grinding efficiency and low power consumption (20% – 30% less than ball mill). The granularity of the feeding material is larger(VRM cement mill is 80mm-120mm, cement ball mill is less than or equal to 30mm). Cement vertical mill occupies less space and saves 30% of construction cost.

Learn MoreThe working principle is that cement is removed from the mill before over-grinding 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.
