Drain & Rinse Screens

Application and Kwatani Product

  • Kwatani drain and rinse screens efficiently recover dense media in the DMS process.
  • Kwatani’s multi-slope screens will improve efficiency and reduce costs by improving heavy media (magnetite or ferrosilicon) recovery in both the product and reject streams.
  • Kwatani can assist in optimizing the feed arrangement onto the screen ensuring the full width of the screen is utilised with low feed velocities to maximise the drainage rate prior to sieve bend and/or Kwatani multi-slope screens.
  • Come and test specific feed material Kwatani’s wet and dry material testing laboratory.

Kwatani Performance Benefits

  • Kwatani drain and rinse screens are custom designed to meet the specific process requirements and ensure maximum heavy media (magnetite or ferrosilicon) recovery.
  • Kwatani’s mechanically robust designs handle the harshest mining applications.
  • In-house finite element analysis (FEA) on each custom design for optimum performance.
  • Kwatani screens are designed for high load capacity, improved wear life and lower operating cost.
  • Minimal maintenance required.
  • Epoxy between bolted side plate assembly surfaces for additional corrosion protection. Deflectors protect the undercarriage of the screen from corrosive media.
  • Kwatani also offers retrofit replacement screens that improve medium recovery while seamlessly matching the structural footprint of existing plant infrastructure with minimal structural modification
