You can't optimise cement grinding with a one-size-fits-all solution. That's why our ball mills are designed to adapt to your requirements, with a high degree of flexibility built in. You decide whether to operate the mill in open or closed circuit, with or without a pre-grinder and with side or central drive, according to your plant layout ...

The 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.

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.
