## dealing with a sagging table when milling long work

24-05-2008I believe much of the reason for sag in mill tables is the peening given to the bottom side of the tee slots by the top of the tee nuts. Especially by people who overtighten everything. Many tables are straightened by peening the bottom side. The curvature is relatively unimportant if you are working on thin work clamped flat to the table.

## Grinding Mill

If the SAG and ball mills feed separate pump systems this is not an issue. If the two stages feed the same pump system, the SAG mill usually drives the discharge arrangement. This is because the SAG mill is usually of larger diameter and may have a requirement for screening of pebbles to protect the mill discharge pumps and cyclones, and to facilitate pebble crushing.
