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.
Cement mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and non-ferrous metals beneficiation, ceramics and other production industries. It makes dry or wet grinding for all kinds of ores and other grind-able materials. Features-Low Investment Cost. This vertical roller mill ...
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.
