WEIR counter flow classifier

The Linatex® flat bottom classifier is a well proven performer for the hydraulic classification of particles by size or density. The Linatex® flat bottom classifier reliably extracts light or small particles from slurry at high efficiency, while displacing a minimum of heavy or coarse particles to the overflow.

Applications

  • Coal/ash separations by density
  • Silica/heavy mineral separation by density
  • Removal of deleterious material from sand including lignite, coal, wood, plastic/paper, clay/ silt and mica
  • Alternative to cycloning:
    - where fines must not be present in the underflow
    - for removing large amounts of clays and slimes
    - for sharp classification in mill circuits
    - at cut sizes coarser than usual applications for cyclones, typically between 100 and 1000 microns

Benefits

  • Extremely efficient washing of soluble or colloidal species from granular particles by virtue of counter-current plug flow washing
  • High sharpness, little misplaced material via direct bed measurement
  • Multiple discharge valves on large units, to continue an even bed draw down without valve blockages or channeling
  • Multiple water injection nozzles result in uniform flow even at minimal flow rates
  • No moving parts are exposed to process slurry, meaning little maintenance is required and a long operating life is achievable
  • Low headroom design results in low capital installation and maintenance costs and easier inspection
  • Zero bypass, no fines in underflow
