DRUM SCREEN (S)
As the rotary screen is used for continuous separation of solid pollution in waste water but with reversed principle.
Polluated water is transported by a pump or flows by its own gravitation into the rotatingdrum screen. The water flows through the
slots of the screen and falls into the outlet tank, then through the pipe out of the drum screen (into the sump,sewerage). Impurities exceeding the opening size of the slot remain on the internal surface of the screen and by the rotation of the screen they are convoyed by the screw to the open side of the screen .The screenings slide down and fall into a container or onto a conveyor.
Drum screen is used especially in different branches of the food-processing industry as are meat-processing factories, slaughterhouses, canning factories etc. It is especially used for the separation of heavy particles (grid, metals, glass) or sticking particles (paper, plastic)
