The ATOX mill's rollers are larger in diameter than most other vertical roller mills, compared to the diameter of the table. This larger roller diameter means that operation with a proportionally thicker grinding bed is less critical as regards uneven wear and foreign bodies in the mill feed. The large diameter rollers further allow.

Coal pulverizers and cement vertical roller mills operate in very similar ways. A table with large sized raw material rotates, while stationary grinding wheels roll over the material to grind it into finer particles. The wheel in these appliions typically has a spherical roller bearing to take thrust loads and a cylindrical bearing to
