mill has a trommel on the discharge end of it Oversize is returned to the mill by a bucket wheel and water jet Trommel undersize was pumped to a vibrating screen where the screen oversize was sent back to the mill and the undersize was pumped to the cyclone circuit Figure 2 shows the flowsheet for line 2 with only the trommel
Built for all ball mills The final bit of good news is that you can enjoy the benefits of the STANEX whatever the size of your ball mill The STANEX is available for all mill diameters in both metric and US units And because the segmented retainer is bolted to the mill shell with a single row of bolt holes only it can also be adapted to
Tower Mills require a settlement zone at the top to separate the media from the slurry this limits the agitation speed to a tip speed of 3ms compared to IsaMill at 2123ms and therefore limits the energy intensity while ball mills can only have a relatively low amount of ball loading before media empties from the mill
