As shown in Figure 4, M 1, M 2, and M 3 are the equivalent mass of the upper part of mill stand, backup roll, and work roll. J 1 and J 2 are the rotational inertia of electrical machinery and upper rolls system of the rolling mill. K 1, K 2, K 3, and K 4 are the equivalent vertical stiffness. Based on Duffing theory, is the equivalent horizontal stiffness of backup roll.

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 applications typically has a spherical roller bearing to take thrust loads and a cylindrical bearing to take
