FLSmidth develop a new generation of their OK™ vertical roller mill.


The international supplier to the cement industry FLSmidth is working on the development of a new version of the OK™ Mill, which has been their standard mill since 1993. The development project has focused on modeling, standardization and cost optimization as well as a technical improvement of the mill.


FLSmidth has developed the OK™ Mills by using 3D-tools including SolidWorks, which has made it possible to make use of the parametric modeling option in the program.


DIS acted as a daily partner with a consultant based at FLSmidth, who assisted in the design of components using parametric modeling in SolidWorks for design automation. The project was focused on three different sizes of the FLSmidth OK™ Mill. In addition, DIS was involved in the further development of the equipment for special transport, as FLSmidth’s products have a size that makes transport challenging. For example, the rollers for the mills are approx. two meters in diameter and weigh about 30 tons.


“In this development project, one of the great advantages of external expertise has been that we have gained a solid knowledge of how to make models in SolidWorks, something we did not have sufficiently. We wanted to achieve a higher degree of what we call product focus, where the various mills become a standard solution, where our customers get a machine at a competitive price and a fast delivery”, says Jens Mose, Department Manager at FLSmidth.


FLSmidth delivers sustainable productivity to the global mining and cement industries. As the market-leading supplier of engineering, equipment and service solutions, FLSmidth improves performance, drives down costs, and reduces the environmental impact of operations.


Present in more than 60 countries FLSmidth has 11,400 employees and had a turnover of DKK 18.8 billion in 2018.
