Screw Screen Operating Principle

Particles that are collected on the filtering mesh of the screen are moved up along the barrel by a rotating spiral. At the same time, the mesh is thoroughly cleaned by peripheral brushes.


Waste compacting is achieved by the decreasing screw pitch. The organic contaminants are flushed from the waste by spray water from washing nozzles on the top of the barrel. Washing water and water pressed from the solid material is taken to the channel upstream of the screen by a pipeline. Washed and drained screenings are discharged into a waste bin at the discharge zone. The screen operation periodicity depends on the equipment automation scheme.


Screw Screen Function

The separation process starts inside the screen which holds back solids only. The internal part of the screen is continuously cleaned by special brushes fixed on the outside diameter of the spiral. As the water runs through the screen the shaftless spiral conveys the solids up towards the compacting module where the material is further de-watered. Depending on the material properties, screenings can be reduced by more than 35% of their original volume.
