motor, mill, bearings and foundation – must be adjusted to get a sufficient safety margin against inadmissible deformation. On the other side the interacting forces between the components must be kept to a mini-mum for economic design. Incidentally, large SAG mills installed as on date are located mostly in critical seis-mic zones.

Where a concrete floor slab is adjacent to the mill foundations, an expansion joint should be used. For convenience in maintenance, the mill foundations should be equipped with jacking piers. These will allow the lifting of one end of the mill by use of jacks in the event maintenance must be carried out under these conditions.
