After welding a large crack in the shell, the mill shell became distorted, which caused the axial and radial runouts to fall outside of the recommended values. They had a mill on hand, but due to operational demands and a foundation crack, they were unable to schedule downtime long enough to install the new gear set for 10-12 months.

the same as the shell axis slope at each pier. Please note that the shell axis slope at a particular tire is not necessarily the same as the kiln overall slope. This is because vertical shell deflection due to gravity may not be the same uphill and downhill of a tire. 6. The tire and support roller radiuses do not vary by more than .010".

A ball mill hardly ever stops working. What is meant to be grounded is fed into the mill from the left through a 60° cone and the product is released from the right through a 30° cone. The rotation of the shell lifts up of the balls on the side of the shell. These keep rising before they drop down to the feed from around the top of the shell.
