High-capacity mill trommel screens


Metso’s robust but light-weight trommel frames consist of carefully selected welded profiles that are covered in a protective layer of wear resistant rubber or polyurethane. Adapting flanges, if required, are available to suit the design of virtually any trunnion or trunnion liner interface. 


  • Frames designed to resist the effects of fatigue using FEA
  • Lightweight panels are easily handled
  • Quick and easy replacement
  • Wide selection of apertures
  • Tapered openings minimize or eliminate blinding
  • The snap-on system offers flexibility; blind panels and panels with different aperture sizes or materials of construction can be combined within the same unit
  • Panels in areas of elevated wear can be individually replaced
