GRIT CLASSIFIER WASHER FL/CDL SERIES

Features:

  • Separation of grit from liquid flows with additional organics washing
  • Receives settle-able grit in liquids from upstream process
  • Solids settle in inlet hopper by gravity and vortex movement created by rotating agitator
  • Organic material is removed by vortex movement in the inlet hopper
  • Inclined shaft-less or shafted screw transports settled grit to discharge end
  • Grit dewaters by gravity in the transport zone
  • Dry grit is discharged vertically into receiver bin or conveyor
  • Trough wear protected by metal or HDPE liner
