  • Hydrocyclone Has These Five Problems? Open This Passage ...

    If the concentration of the underflow is too large, the underflow will be discharged in the "columnar" or intermittently "lumpy" shape. Solution: 1)The high concentration of underflow may be caused by the feed slurry concentration or the underflow port is too small, which can add an appropriate amount of water to the feed first.

  • Hydrocyclones - an overview | ScienceDirect Topics

    A hydrocyclone can handle very high slurry throughput rates, and often an entire battery of hydrocyclones can be found at a mineral processing facility. The advantage of fast processing by a hydrocyclone is somewhat offset by the associated high impingement wear rate of the hydrocyclone internal surface lining by the fast-moving abrasive slurries.
