Features & Benefits

Screen Deck

 

  • Up to five decks stacked one above the other operate in parallel, giving high capacity in a compact footprint
  • Easy access for maintenance, servicing, and replacement of screen panels
  • Simple drawbolt tensioning system permits all panels to be changed on a five-deck machine in about 30 to 40 minutes
  • Urethane screen frame coating provides abrasion resistance
  • Low sound production
  • Dual 2.5 HP (1.9 kW) Super G® vibratory motors are standard on the Stack Sizer providing uniform linear motion over the entire screen width and length of all screen decks
  • Super G motors offer maintenance-free, greased-for-life bearings (Two-year warranty)
  • Optional Super G2® vibratory motors offers a continuous recirculating internal oil lubrication system (Three-year warranty)
  • Polyweb Screens offer up to 45 percent open area for maximum flow capacity
  • Full range of openings down to 325 mesh (45 μm) permits screening from coarse to super fine particles
  • Unique non-blinding design for optimum efficiency and performance
  • Long Lasting – 6 to 12 months is common
  • Equalizes feed flow from source to each deck for optimal separation efficiency
  • Custom-designed to meet process and layout requirements
  • Available in wide range of discharge outlets from 2-way to 15-way
