Shaftless Spiral Screen as Compact Cleaner or Channel Screen

SPIROGUARD® Screen

The SPIROGUARD® combines screening, conveying, dewatering and removal of solids from effluent and process streams in one compact machine.

The unit is robust, easy to install and, with only one moving part, virtually maintenance free. Slow speed combined with automatic intermittent operation ensures a reliable and efficient system.

SPIROGUARD® Channel Screen (CS) SCREEN
SPIROGUARD® CS Screens can be installed for a variety of flow rates and water levels. The angle of inclination depends on the concrete channel specifications. 

Typical applications are:

  • Inlet works in sewage treatment plants
  • Pulp and paper industry
  • Wine industry for extraction of seeds and skins
  • Food industry

SPIROGUARD® CC SCREEN
The SPIROGUARD® CC Screen is designed as a standalone unit for pump-fed applications. Ideally suited as a tanker reception facilitator screening seperation unit, it is robust and easy to install. With only one moving part, this unit is virtually maintenance free. Slow-speed combined with automatic intermittent operation ensures a reliable and efficient system.

 
PRODUCT BENEFITS
  • Low operating speed = low maintenance costs
  • Low energy consumption = cost savings
  • Compact, robust design = that the machine is virtually maintenance-free
  • Hinged covers = easy inspection of shaftless screw conveyor 
  • Shaftless Spiral (Screw) conveyor have got no intermediate or end bearings = material build up or blockage will never occur

SPIROGUARD® CS – Channel Screen  

  • Aperture 2mm to 6mm perforated holes and 1 – 3mm wedgewire.
  • Hydraulic flow up to 500l/sec.(11.4MGD)
  • Standard and custom designs to suit client / site specific requirements.
  • Shaftless spiral that do not require a centre-pipe, intermediate or end bearings – thus minimising any potential for undesired blockages.
  • Space saving prefabricated solution with minimal civil works and installation time.
  • Unique pushing drive configuration with adjustable back pressure settings. [with optional compaction head].
  • Low capital cost, low power consumption, few moving parts – therefore low maintenance and operating cost.
  • High screen capture ratio’s; [perforated screen media]
        2mm Ø @ 75-83% Estimated
