  • SAG Mill Control It Shouldnt be that Hard

    Sag Mill Control It Shouldnt Be That Hard

    SAG Mill Control It Shouldnt be that Hard.SAG mill control fundamentally means managing the load in the mill by adjusting the feed rate of ore to the mill andor manipulating the rotational speed of the mill. The best way to measure load is to mount the mill on load cells. The load cells are calibrated to measure the total weight of water, grinding media balls and ore in the mill ...

  • Whats the Difference Between SAG Mill and Ball Mill

    Whats The Difference Between Sag Mill And Ball Mill

    Whats the Difference Between SAG Mill and Ball Mill.Nov 26, 2019 The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 4000, while the ball mills ...
