At its core, a vertical roller mill operates by rotating a cylinder-shaped mill table while maintaining a set distance between the table and the rollers. The distance between the table and the rollers is known as the ‘gap’, which is controlled by adjusting the height of the rollers. The mill table is driven by an electric motor and rotates
