Our best-in-class OK™ Mill is a globally successful vertical roller mill solution for grinding raw material, cement and slag. Its cutting-edge design features consistently deliver the highest quality products with the greatest efficiency. It is affordable to install and cost effective to operate over your cement plant's lifetime.

The laboratory of a cement plant. With the help of vertical roller mills or other types of crushers, the raw materials are blended and further ground into smaller pieces of raw meal in the cement plant. In a roller mill, the rotating roller rotates continuously on the grinding table and crushes the material to fine powders, and finishes the job.
