Rotary Drum Grille

Usage Function

The rotary drum grille is generally installed in small to medium-sized wastewater treatment plants to remove solid particles from the wastewater. The fluid hits the grille and penetrates between the bars before being discharged below the cylinder into a collection tank, while the solids are retained on the surface of the grille and then transported through the rotation of the drum. A scum blade diverts the screened material into a dedicated container. Overload protection is provided by electronic devices that monitor the motor’s absorption.
