Hydrosizers

When extremely sharp classification is needed to separate <4 mesh (<5mm) granular material by size or specific gravity, McLanahan Hydrosizers™ have efficiencies of separation comparable to Sizing Screens but at a fraction of the footprint and cost. A producer who needs tight control over classification or who wishes to separate minerals of two different specific gravities or remove lightweight contaminants would be an ideal candidate for a Hydrosizer™.


  • Extremely sharp, high-efficiency size classification between 100 micron (150 mesh) and 600 micron (30 mesh)
  • Effective separation of minerals of different specific gravities
  • Side accessible teeter water system allows customers to maintain unit without entering tank
  • Anti-fouling nozzles for water distribution
  • Removal of organics
  • Low operating costs
  • Rapid payback on investment
  • Proprietary linear discharge underflow valve
