After Magnetic Separation, the ASR stream consists of approximately 10-15% Non Ferrous metallics (Aluminum, Zinc, Brass Copper, etc), mixed with Non-metallics (glass, sand, dirt, plastics, rubber, wood, etc). The first typical step in processing the ASR stream for maximum metal recovery is to screen the stream of material, for two purposes: first; to remove fine material from the stream as waste, and second to separate the ASR into different smaller streams, by size, to allow for optimum performance of further downstream metal capture devices. The primary method of separation is a rotating tube, with screens that will perform either task, and/or flat deck screens ; primarily for most efficient separation of fine material. The Screens can be designed in single or multiple stages, as production levels may require.

Technical Design Features:

• Steel Support Structure, with Wrap Around Platforms, Ladder access.
• Hexagonal or Octagonal Tube Design. Skeleton Frame with Bolt-In Screens.
• 6 Degree Tapered Skid Frame with Side Skirts.
• Inlet & Discharge Hoppers, as required.
• 60” Tubes, or smaller units, use Dual Friction Drives with sealed Gearmotors.
• Larger Tubes, use #200 Chain Wrap Drive with Single Gear Reducer Drive.
• Tube supported on Hi-Load Urethane Wheel Assemblies.
• Articulated Urethane Thrust Rollers. Heavy Duty Machined Roller Tracks.
• Flat Screens use Step Deck Screens to separate Fines, & minimize plugging.
• Dust Cover for Weather Protection & improved performance.

Options: Variable frequency Drive, Patented “Select Screen” allows for adjustable openings in Screens.
