FSM - Grab Bar Screen

The waste water flows through a bar screen made of steel or stainless steel, while screenings are held back. Solid matter is picked up by our special grab directly at the bottom of the channel without the need for a base step. The teeth of the grab act between the bars of the screen thus preventing jamming of the screenings. A pivoting scraper discharges the screenings into a container, wash compactor, screw conveyor, conveyor belt etc. Opening and closing of the rake is achieved by a drive or a guide track.

The position of the rake is controlled by a rotary selector switch. Thereby different positions on the screen field can be reached by the rake. For digger operation the rope is controlled by a slack rope weight.

Applications in municipal and industrial clarification plant

• waste water pre-treatment / coarse screening

• High reliability through robust construction
• The coarse bar screen allows the passage of grit without malfunctioning
• Screenings are prevented from falling back on the screen by a sheet steel apron
• Screenings conveyed positively to the discharge point
• Secure guiding of grab shovel via double bearing arrangement
• Excellent cost/performance ratio
• Low maintenance costs
• Suitable for outdoor sites / operation in winter
• Easily adapted to suit changed operating conditions
• If required, machine can be completely hygienically encapsulated
• The FSM coarse bar screen unit has proved itself in practice at home and abroad
