The water supply of the vertical roller mill increases, the concentration of ore grinding becomes thinner, and the fineness of ore grinding becomes coarser. On the contrary, when the water supply of the vertical roller mill decreases, the concentration of ore grinding becomes larger, and the fineness of ore grinding becomes finer.
The size of the flushing water at the discharge port of the vertical roller mill
The flushing water at the discharge port of the vertical roller mill becomes larger, the overflow becomes thinner, and the overflow fineness becomes finer. On the contrary, the flushing water at the discharge port of the vertical roller mill becomes smaller, the overflow becomes thicker, and the overflow fineness becomes coarser.
Therefore, under other conditions including the same amount of ore, to increase the fineness of the grinding, the water supply of the vertical roller mill can be reduced, and the water flushing at the discharge port of the vertical roller mill can be increased. It is best to adjust these two conditions at the same time to ensure that the change in the amount of slurry caused by the adjustment of the grinding fineness is minimized, which causes the fluctuation of the flotation.
