Abstract
A vibratory filtering screen assembly comprises an upwardly inclined member (12) on which is mounted the main filtering screen (14). At the exit (16) of the main screen is a secondary screen module (20) comprising a plurality of transverse supports (22) of rectangular section on which is mounted a screen (24) held in position by a silicon beading (26). Surrounding the secondary screen is a perimeter border or dam (28) for containing the discharge which is passed on to the secondary screen. In operation slurry is fed onto the main screen (12) where vibration passes it to exit (16). Wet solids components of the slurry drop into the secondary screen (20) where the vibration continues to dry out the solid particles, waste liquid being diverted away by a plate (30).
