Case Study - Greenway Recycling

  • At Portland, Oregon based Greenway Recycling, developing personal relationships is the key to building a lasting partnership. “I really enjoy the idea that there could be a personal relationship, so I know who to call.” says co-founder Terrell Garrett. As a customer of West Salem Machinery for over 12 years, Garrett knows that when his business needs help, WSM will be ready to answer the call. 

  • When large tramp metal caused catastrophic damage to Greenway’s WSM 4864 horizontal grinder, the business faced a serious hurdle getting production back up and running. “We hit a track pin off a 450 excavator and it did a huge amount of damage to the machine. It was midsummer, our busiest time of year. So we called West Salem for help.”

  • “West Salem dropped a bunch of other work to supply us with parts, replaced what the machine needed, and put the grinder back together for us.”

  • Garrett knew that repairing his grinder was only a temporary solution. “We sat down with West Salem and said ‘This is going to happen again’. We have a huge tramp metal problem.” Greenway needed a more permanent solution.

  • West Salem developed a new hammer system for Greenway’s grinder to hopefully prevent serious damage when metal entered the grinder in the future. Greenway tested the system and reported results to West Salem.

  • The new hammer system provided lasting results. The improved durability and production of WSM’s new system not only successfully eliminated costly downtime, the machine improved Greenway’s profitability. “Before I bought the grinder, my damage parts bill was averaging $57,000 a year. Now we’re about down to $10,000.”

Urban Wood to Animal Bedding

  • A typical system starts with a Chain Metering Bin to deliver waste wood to a Disc Screen, with “overs” going to a Primary Grinder which reduces material down to an approx. 1 ½” minus
  • First stage metal removal is achieved with a cross belt magnet in conjunction with magnetic head drum on a belt discharge conveyor or metal detector, with automatic dump to ground
  • Secondary processing through a WSM Super Shredder with air assist or full air discharge produces finished fiber
  • The final stage is screening for final product sizing based on finished product specifications. This is commonly done with either an Oscillating Screen or Vibrating Screen for precise classification
