Holo-Flite® Features

  • Particles are indirectly heated or cooled via the hollow flights, shaft, and trough
  • Heat transfer is achieved by using water, steam, or thermal oil
  • Heat transfer process can be easily controlled to achieve the best results
  • Extreme expansion and contraction of the screw  is easily handled by the Holo-Flites patented twin pad design that allows for successful operation up to 1,200 degree Celsius for product cooling

 Product system offering/ ancillary equipment offering

Wide range of process applications

The Holo-Flite processor suits many applications including, but not limited to: 

  • Cooling calcium carbonate, iron oxides, fly ash/ incinerator ash, limestone
  • Drying alumina, carbon black, sodium, plastics, chloride, molybdenum, waste sludge and coal
  • Heating limestone filler, petroleum coke, petro-chemicals, sand

Continuous conveying

Particles are heated or cooled as they come into contact with the surfaces of the hollow flights, shaft(s) and trough.  The product is continuously conveyed by the rotating screws along the jacketed trough.
