Beaudrey - Model R Type -Rotating Chain Trash Rakes

"R" Rakes are installed in the screening plant upstream of the travelling screens or the drum screens. The water flows across the inclined bar rack where the debris are arrested. The trash collecting rakes are held on two endless chains. They travel down, well clear of the bar screen, run around the bottom rail meshing between the bars. The debris are removed and loaded into the trash collecting rakes, they travel upwards. At deck level, the debris are swept out of the rakes into the collection trough or basket. Two or three travel speed operation is provided. Cleaning is started either by a timer, the operator or the head-loss monitoring system.
