learn moreRod mills, how they function Mine
The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65% rod charge by volume. The limits on charge level are (1) keeping the feed end trunnion open so that feed will get into the mill, and (2) keeping the rod charge low so rods will not work their way into discharge openings where they can cause rod tangling.

Shell plate liners are individually manufactured for each application to suit the shell of the mill and to integrate with the lifter bar. Whilst shell plate liners can be manufactured up to 8 metres long, the lengths provided are usually designed for manual handling on site and to integrate with the lifter bar configuration that is normally used to attach the liners to the mill shell.

A laboratory scale mill measuring 526 mm in diameter (inside liners) and 400 mm long was utilised in the experimental work. The mill configurations and test conditions are described in Table 1. Fig. 1 illustrates the details of the bevel liners used in the experimental work. The liners were cast with integral lifters having a face angle of 60° tangent to the mill shell on one side and 45° on

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the pebble removal.
