The TurboDrum IN is installed in a channel at a 35 degree angle. For pressure feed applications, the same unit can also be installed as a self-contained TurboTank™ system. The operation cycle controlled by monitoring differential head loss across the screen is performed by rotating the basket with the process flow entering the internal diameter of the screen and exiting through the screen elements to the outside. The screenings are retained on the internal surface of the screen by paddles fixed longitudinally to the inner screen surface which carries the material to the top where it is sprayed and falls into the receiving hopper. The receiving hopper spiral conveys the screenings material through the optional washing and compaction zone and discharge outlet.
