The mill, with its heavy weight, rests statically on the slide shoe surfaces. To lift the mill a highpressure pump pumps lubricating oil into the space between the mill shell and the bearing. This process is referred to as hydrostatic lubrication. When the mill rotates the movement of the mill running surface creates hydrodynamic lubrication.
