Gravity flow rotational drum screen

Drumtec is an internally fed rotary drum screen. Wastewater flows into the drum, where a deflector divides it evenly. Influent water passes through the perforated plate, which screens solids from the flow. A large flight auger carries the waste to the end of the drum, where it empties into an integrated washer/compactor or directly into a dumpster

Screen diameters can range from 0.5 to 2 meters (1.6 to 6.6 feet), while the lengths can vary from 2 to 6 meters (6.6 to 19.7 feet). There are three modes of operation which include: • Low Flow- no drum movement. • Intermed iate Flow- drum

    The water to be filtered flows (due to gravity or pumping) into the inlet openings of the drum. On the inside of the drum, dirt will remain behind as a result of the mesh that was fitted across the drum. As the screen gets more polluted, less water will flow through the drum. The water level behind the drum will fall (in case of a gravity

    Key physical properties of rotational molding powders are dry flow (also called pourability), particle distribution, and bulk fac-tor. Testing for these properties is done in accordance with ASTM D-1895. Dry flow describes the relative flow property of a powder at ambient conditions. Shorter flow times indicate better flow
