Abstract
A vibratory screening machine as described separating solid particles from liquid in which a fine mesh screen (30) includes an inclined region extending upwardly to a discharge edge (34) over which solid material (36) separated by filtration can pass. Vibration of the screen (30) causes the solid particulate material to move towards the discharge edge (34). The screen (30) forms the base of a reservoir having sides (10) and a weir or dam (46) at the opposite end to the discharge edge (34) and is slidable in and out to provide for cleaning and/or replacement. A suspension of liquid and solid particulate material is supplied to the machine along a pipeline (28) and is discharged onto the rear end of the screen (30) from a discharge head (24). One or more intermediate screens of similar design may be located above the main vibrating screen and above one another and the suspension of liquid and solid material discharged onto each of the screens overflows onto the rear end of the screen immediately therebelow. Trays (68) and (70) are provided to catch liquid draining through.
