Tega's Solution for Reducing SAG Mill Shutdowns by 75% in Cadia Valley (Australia)

Customer’s Concerns:

• The heavy balls settle at the bottom & slurry start moving over it. Due to the absence of any forward force, balls always stay inside & get accumulated.
• Content of water in discharge slurry was high which need to be resolved.

Solution:

• We modified the DAM layout as per our EDEM analysis. We modified it in such a way that it start giving forward push without affecting required retention time(i.e. 16.8-17 sec).
• We increased the open area as well as aperture flare (friction zone reduced) which results in the reduction in water content in discharge slurry.
