A 1.5 mio t/a cement plant is having a closed circuit ball mill for cement grinding: The mill has been operating with satisfactory performance in-terms of system availability and output, however power consumption was on higher side. 3.1 System Description Mill Rated capacity 150 t/h OPC at

The OK™ mill has been FLSmidth’s standard cement VRM since 1993. Since its introduction, the OK mill has proven to be the most efficient cement VRM available, with the highest reliability and ease of operation. In 2017, FLSmidth introduced the OK raw mill, which is designed with the same proven technology and modular design as the OK cement

Recently, the vertical roller mill having great grinding performance is widely applied to the raw material grinding process. However, tube mill, which has about 30% poor grinding performance as power consumption, has been still used many existing cement plant. The improvement of this tube mill grinding system is highly expected. Descriptions
