The high underflow concentration may be caused by the feed slurry concentration or the ultrafine vertical mill underflow opening is too small. You can add an appropriate amount of water to the feed first. If the underflow concentration is still large, you need to replace the larger underflow opening.

If the underflow is discharged in an "umbrella shape", but the underflow concentration is less than the production required concentration, it may be caused by the low feed concentration. At this time, the feed concentration should be increased.

The "fine underflow clamp" may be caused by the underflow orifice wear, the underflow orifice is too large, the overflow pipe diameter is too small, the pressure is too high or too low, it is necessary to adjust the pressure first, and then check whether the underflow orifice is worn or replaced A small underflow port is gradually adjusted to normal production state.
