Extrac-TEC's Heavy Particle Concentration (HPC) technology allows .TEC's patented and proprietary reverse spiral . The reverse spiral concentration belt is an ultra-high abrasion resistant, long retention-time concentration spiral which separates heavy particles which are . spiral concentrator belt is designed to deal only with the undersize material scrubbed and screened from this bank-.spiral concentrator reverse,spiral concentrator reverse,Process Description - Transverse spiral concentrator belt - Extrac-TecThe transverse spiral concentrator belt is patented and unique to IE-TEC's HPC systems. The belt is set at an incline and material fed onto the belt is washed down-slope. The motion of the belt combined with water flow cause heavy particles to settle. These heavy particles are drawn up-slope by the reverse spiral whilst.John Frank
