New chapter for the OK mill
With the market trend for large-capacity plants demanding bigger and bigger mills, FLSmidth’s OKTM mill is now also available for raw grinding applications. The largest VRM for raw milling in the world, the FLSmidth OK 54-6 mill, is currently installed at Semen Padang’s Indarung VI line in Indonesia. By John Terembula, FLSmidth.
The OK mill can be operated with a number of rollers out of service, minimising the risk of lost production
The OK mill has long served the cement industry as an energy-efficient and reliable solution for cement grinding. Since the 1980s, the robust design has evolved to include the best-available technology and incorporate the knowledge gained from over 150 installations. This has helped it continue to exceed the expectations of the cement industry in terms of power consumption, availability, product quality, and flexibility to grind the most diverse mix of materials. Now, the same proven technology and modular design approach of the standard OK cement mill is available for raw grinding applications. In early 2017 an OK 54-6 raw mill with 8700kW of installed power successfully began operation.
