Aqseptance Group offers a wide variety of Rotary Drum Screens to fit your needs and specifications. View the unique features of each screen below to compare them.

RSI unique features

• No center/drive shaft required in the discharge conveyor
• Significant larger particle sizes can be transported – The spiral is open axially in the conveying direction at the discharge, i.e. no blockages due to long-fibred screenings or screenings prone to clogging – Ease of access to pressing zone – Pressing zone with back-pressure flap, i.e. influence on DS-contents possible
• The drainage zone is adjustable and exchangeable. The design of the slotted bottom results in an increased drainage capacity and a self-cleaning effect, so that the RSI operates completely without a brush and wear rails.
• The shaftless spiral ensures a blockage-free discharge and allows the conveyance of large solid parts.
• Ease of maintenance due to good accessibility to drive
• Easy and fast maintenance and thus low costs due to bolted main parts of the unit

RSI-DD unique features

• The screw conveyor for capture and transport of the solids retained are equipped with suitable brushes in the sieving zone to clean the drainage area in the conveyor. The brushes are made in segments, bolted on the spiral, allowing an easy replacement of the worn pieces only.
• Easy and fast maintenance and thus low costs due to bolted main parts of the unit
• Double drive
  • The rotation of the drum is independent of the rotation of the spira
  • Due to the independent drive, the screenings can be run empty in the hopper of the conveyor trough.
• Open drum inlet Zone
  • free inflow of the Screenings
  • without rotary arm low head loss
  • no entangling

RSI-SD unique features

• Easy and fast maintenance and thus low costs due to bolted main parts of the unit
• The screw conveyor for capture and transport of the solids retained are equipped with suitable brushes in the sieving zone to clean the drainage area in the conveyor. The brushes are made in segments, bolted on the spiral, allowing an easy replacement of the worn pieces only.

RSI-DF unique features

• Double filter system:
  • In the same unit a fine and coarse screening sieve – Fine sieve is protected by overloading in case of large solid – Coarse filter with back wash system – Reduction of investment by omission of a separate coarse Screen
• Double drive
  • The rotation of the drum is independent of the rotation of the spiral – Due to the independent drive, the screenings can be run empty in the hopper of the conveyor trough
• Open drum inlet Zone
  • free inflow of the Screenings – without rotary arm low head loss – no entangling
• The screw conveyor for capture and transport of the solids retained are equipped with suitable brushes in the sieving zone to clean the drainage area in the conveyor. The brushes are made in segments, bolted on the spiral, allowing an easy replacement of the worn pieces only.
