Building this third SAG mill at PTFI will make up for the added crushing power that the ore-pass chutes and their generous gravity contributed during open-pit times. This third SAG mill will feed PTFI's existing pair of SAG mills. But due to the paucity of flat land in the uber-steep topography at Jobsite, building a new structure is not just ...

Have had 30" of snow on it and it's stood 21 years. It does sag slightly. But not as bad as an oak beam of the same size and span on the same building. With my new mill, I used 25' steel with no worries. If you only plan on building this once, use steel and build it twice as big as you think you will ever need. I did and it isn't big enough yet!

Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
