Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear. Three different mill ...

I have a supermax ycm1 1/2 va and somehow the feed needs (2 nut design) came out of the bracket so I removed the table and lead screw to feed the assembly back into it but noticed there were no adjustment screws at all not even a tapped hole for an adjustment screw to go into. The bracket does however have a boss where it looks like the screw would normally go.
