• 20:45, 25 May 2026 Alex Doll talk contribs created page Pebble crushing or not (Created page with "== Pebble Crushing, or not == The choice of adding a pebble crusher to a circuit requires balancing the following: * the ratio of rod mill to ball mill work index values * the desired transfer size of the grinding circuit (what is the model running at) * energy efficiency of the grinding circuit === Ratio of work indices === If the rod mill (and crushing work index, to a lesser extent) are higher than the ball mill work index, then the circuit will probably require peb...")
• 20:42, 25 May 2026 Alex Doll talk contribs created page HPGR or SAG (Created page with "== HPGR or SAG? == Choosing an appropriate grinding configuration is important for conceptual design. Here are some things to consider when making the choice between an HPGR-ball mill circuit and a SAG-ball mill circuit. ===Work index ratios === Having a hard ore is not a valid reason for choosing an HPGR circuit, the ore must be hard in a certain way. More specifically, it should have a rod mill work index greater than the ball mill work index, and a ball mill work i...")
