Technical Details

Conical, low speed screw presses are suitable especially for difficult sludges which can not rapidly be pressed or sludges which contain also pressable material (high torque can be used).

Pressing is made in the whole screw length acc. to the sludge properties. The best possible results are achieved by means of tailor-made process design.

AF-Press™ is equipped with :

  • A conical screw
  • An annealed, thoroughly machined and polished screw shaft
  • A tailor-made thread for the sludge in question
  • A low rotation speed (≥ 0.15 rpm)
  • A possibility to use low pressure steam for the most difficult sludges and for the highest dryness
