Putting a Ball or SAG Mill on Care and Maintenance
· The mill needs to be jacked high enough to get the last shim in place so that when the mill is lowered onto the shims it is no longer resting on the bearings. If that amount of lift creates interference with the bearing cap it could wreck the seal or damage the cap if it is bolted rigidly in place.
