FSM is the #1 supplier of perforated plate, belt screens in the world with 2000 installations worldwide since 1987. A continuous screen belt of perforated plate panels traps solid material on the surface of the screen and moves it to the upper deflection point where a brush cleans the debris from the plate. Depending on the length of the screen, a number of strategically placed lifting tines are located on certain plate panels. These tines are designed to capture gross solids and dislodge and remove rolling matter that accumulates in front of the screen at the base of the channel.
