Grinding Mill Foundations

23/09/2014  Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).

Vibration Control, Mounting and Levelling of: ROLL GRINDERS

mills and precision machine shops to grind smooth and textured rolls to very tight tolerances. On first appearance they look rather like a lathe but in reality they are required to achieve much tighter tolerances as the rolls that are produced by the grinder dictate the accuracy of the metal or paper that will be produced through the rolls in the factory. Rolls can be up to 10 meters in length ...

Manual design of SAG/ball/rod mill foundations ...

14/03/2007  We took one look at the foundation and permitted a modern SAG Mill to be installed on the old foundation. With respect for what it was, it's not going anywhere, and will not be experiencing any vibration issues anytime soon. My back-of-the-envelope check gave me a natural frequency somewhere in the 0.000X range. With respect for the environment, the foundation should have only needed a
