Optimising bagasse diffuser performance using percolation velocities* [Full subscriber]

Abstract         Invicta Mill at Giru, north Queensland, is a dual-train sugar mill that crushes about 3 Mt of cane each season.  The factory has a traditional milling train on the A-side, and a bagasse diffuser on the B-side installed in 1995.  During the 2019 crushing season, Invicta Mill had several reliability issues with the bagasse diffuser.  The root cause of these issues was difficult to identify and prompted an investigation to better understand how this unit operated.  The objectives were to eliminate the diffuser-reliability issues experienced and improve the B-side bagasse loss for which the diffuser was a key contributor.…
