    Oct 19, 2020· The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in

  • Effect of lifters and mill speed on particle behaviour

    May 01, 2017· Furthermore, when ψ = 100 %, the curve of the torque declines rapidly when N l ⩾ 6 because a large quantity of centrifugal particles exist in the mill under this condition. Thus, the effects between particles and liners are weak, and the particle area ratio increases. As a result, the torque of the mill
