Vertical 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.
