1. West Salem Machinery Waterfall Disc Screen. West Salem Machinery (WSM), Salem, Ore., has announced the development of a new screening design—the WSM Waterfall disc screen. Features include:

  • Designed to deliver high-capacity fines screening and to improve screening efficiency because of increased material agitation
  • Uses multiple-roll screening decks that agitate and tumble the mat of material being screened as it falls from level to level
  • Tumbling movement is similar to a waterfall in that the mat is blended as it falls and fine particles that were in the upper portion now have a chance to be screened on the lower deck
  • Tight spacing between discs allows a variety of fiber materials (bark, chips, sawdust, shavings, hogged wood, compost) to be sorted by size (thickness and length)
