## Sag Mill Foundations Forces

The SAG mill consists of a center shell and 2 heads, one at each end: the feed head and the discharge head. The shell and the 2 heads consist of three sections. At the centre of the head section a trunnion is bolted. The trunnion supports the mill and the mill rotates on the trunnion. The trunnion rests on pedestals.Coarse ore from the Coarse ...
