Abstract

The present invention relates to a vibratory screening apparatus which comprises a vibratable screen element (2) mounted in a basket (4), which basket (4) is mounted over a reservoir (6) which contains and holds a pool of liquid slurry (8). A first end (10) of the screen element (2) is disposed within the reservoir (6) such that it is submerged in the body of liquid slurry (8). The reservoir has a deep end (12) in which the first end (10) of the screening element (12) is disposed and a second shallow end (14) above which a median portion (16) of the screening apparatus is disposed. The second end (18) of the screen element (2) is disposed above a portion (20) of the reservoir which extends above the surface of the body of liquid slurry held within the reservoir (6). Vibration means are provided for vibrating the screen element such that oversized solids in the liquid slurry in use of the operation are dewatered on the screen element and are discharged from the second elevated end of the screen element and underside solids pass through the screen element, where they may be collected. A vibratory screening machine is also described.
