Converting a ball mill from overflow to grate discharge

Grinding mills, including SAG (semi-autogenous grinding) mills and ball mills, consume approximately 60-70% of the total energy cost of the entire mining operation. The mills are installed with large motors, up to 20+MW, which impart the required energy to successfully process many tonnes per hour and grind the rock to a …

Odd shape of wet ball mill ball scats.

Our wet Ball Mill griding media reject (scats) from the trommel screen is an odd shape ( see photo attached). I'm not use to this wear shape of grinding media in a ball mill. Normal wear of grinding media in my experience is down from a spherical to a non-spherical (egg shape) or a homogenic spherical wear to a smaller size, not the octagon ...

Trunnion Magnet on SAG or Ball mill to remove ball scats

Just wondering if anyone has a ball or SAG mill with a trunnion magnet to remove scat steel and if they are willing to share the results. Looking into getting one for our SAG mill but looking for proof that it actually creates power savings, ball consumption savings, etc to justify the project. We process gold ore at about 200 TPH. Thanks!

Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed. It grinds it up into a compound to make processing easier. You'll find a similar process in sugar cane mills. These steel …
