WSM Screens

Disc Screens

With WSM’s high-volume chip screening and optional single-pass chip resizer, achieve superior productivity and quality while gaining space-saving efficiency in one seamless solution. WSM Disc Screens can be configured with our unique waterfall arrangement to help agitate and turn material, further increasing screening efficiency.

Typical Applications

  • Screening hog/boiler fuel at high volumes for biomass power plants to separate acceptable fuel size while directing screen “overs” to wood grinder/hog (see WSM Vertical Feed Grinder).
  • Chip screening in pulp and paper mills for proper sizing of wood chips and removal of over-sized chips, with “overs” sent to chip re-sizer (see WSM Chip Re-Sizer).
  • Gross overs removal from truck dumps to eliminate large contaminants from material flow and prevent down stream plug-ups.
  • Fines screening to remove sawdust and shavings from wood chunks.
  • Multi-stage screening to provide two separation points including “fines”, “accepts”, and “overs”.
