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.

1.. IntroductionConventionally multi-compartment ball mills are used in finish grinding of cement. However, they are relatively inefficient at size reduction and have high energy consumption, so it is increasingly common to find grinding technologies such as High Pressure Grinding Rolls (HPGR), vertical mills and Horomill ® in cement plants.

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind.
