Rotary Drum Screen Removes Solids From Different Effluent Streams
The 24 RDS 24 self-cleaning rotary drum screen from Munson Machinery is designed to remove solid materials from waste streams at high rates. The unit contains a rotating cylinder that is 24 inches (610 mm) in diameter by 24 inches (610 mm) long and is constructed of wedgewire screen. Effluent discharges from a head box overflows a dam and flows onto the outside of the rotating cylinder, allowing water to pass through the wedgewire into the cylinder. A doctor blade scrapes sludge and debris collected on the outside of the cylinder, while an internal spray line dislodges particles blinding the screen.
The separator is intended for food, sewage, pulp and paper, rendering, pelletizing and other applications in which solids must be removed from slurries in high volumes. The variable speed unit is equipped with wedgewire screen in a range of seven orifice sizes from .010 to .100 inches (.25 to 2.54 mm), offering capacities from 200 to 930 gal/min. (757 to 3,520 liter/min), respectively.
Larger models are available with drums of 24-inch (610 mm) diameter in 36, 48, 50 and 72 inches (914, 1,219, 1270 and 1829 mm) lengths, and with drums of 36-inch (914 mm) diameter in 96 and 120 in. (2,438 and 3,048 mm) lengths. Capacities range from 200 to 4,650 gal/min. (757 to 17,600 liter/min.).
