MetalDirector™

The NRT MetalDirector™ sorting system uses sophisticated metal-sensing technology to readily identify and eject ferrous and nonferrous metals from a mixture of materials. The sorter can efficiently recover aluminum cans from a process stream. The sorter features an eddy current induction detection module incorporated into a fast-moving conveyor. The MetalDirector™ detects and identifies metal objects and their locations within the fast-moving material feed stream on the belt. The metal objects are then ejected by a brief, precise blast of compressed air as they discharge off the end of the conveyor. The system incorporates rugged heavy steel plate construction for the sorting enclosure, self-cleaning live roll splitter, and an advanced easy-to-use operator interface.

Features

  • As little as 0 ppm metal in commodity
  • Small footprint standalone machine
  • Advanced detection array
  • Low product loss
  • Uptime of 99% or more

Applications

  • Recovery of aluminum can product from a mixed container stream
  • Removal of metals from a materials process stream
  • In the MRF Industries, the MetalDirector™ can be installed into an accelerating conveyor of an optical sorter and integrated with the sorter’s ejection system for the removal of aluminum cans and other metal objects
  • In the PET Recycling Industries, the MetalDirector™ can be added to any existing NRT sorter to detect and eject metals including aluminum cans or other metals

Technology

  • Induction metal sensing
  • Fastest solenoid valves in the industry to minimize product loss
  • Object-tracking algorithm identifies and ejects metal as small as 1 mm
  • 24″ (3,600 lbs/hr) to 108″ (16,200 lbs/hr)
