DF-6000™ Deflaker

The development of the DF-6000 deflaker stems from over 60 years of DD® refiner and deflaker design. The DF-6000 deflaker’s robust cast iron and stainless steel construction is based on GL&V’s highly successful DD6000 refiner. The DF-6000 deflaker includes a completely removable and re-buildable rotating assembly for ease of maintenance and increased reliability and a hinged access door for easy access to the deflaking cavity for filling changes without requiring the disconnection of either the stock inlet or outlet lines.

The DF-6000 deflaker combines the features of a fixed deflaker ring set and a mating rotating set mounted to a head which is coupled to a drive motor. The distance between the mating ring sets is fixed at installation, resulting in a more uniform clearance between the rotor and stator sets producing uniform low energy deflaking without the introduction of additional refining. GL&V’s proven tangential inlet technology permits operation at higher capacity compared to similar sized competitor units though the pre-rotation of incoming stock.

  • Stainless steel wetted construction
  • Simple hub and rotor arrangement for easy filling changes
  • The rotating assembly consists of an alloy steel shaft supported by spherical roller bearings and a thrust roller bearing
  • Effective labyrinth type deflaking fillings repeatedly accelerate and decelerate flakes, resulting in the loosening and eventual release of the bonds between the individual fibers without introducing additional refining or dropping freeness
  • Hard faced wear sleeve minimizes frictional damage from gland packing. O-Ring seal on door
  • Stainless steel wetted construction
  • Various filling designs available for specialized applications
  • Additional mechanical seal options are available
  • Rotor removal arm
