· re vibration vertical roller mill. There are a number of reasons for high vibrations in vertical roller mills, such as: 1. Failure of the grout or cement material under the steel beams embedded in the foundation top, which allows oil to penetrate, further degrading the concrete. The anchor bolts, which are typically large in diameter, continue to exert force into the foundation, and the base
