ABSTRACT:
An ultrasonic sieving apparatus (10) is described which comprises a de-coupler (18) for enabling a combination of a transducer (T) and a first resonator (16) to be supported with respect to a sieve which includes a separation medium (14) provided in a frame (12) such that vibrations generated by the transducer (T) are transmitted to the separation medium (14) via the first resonator (16). The first resonator (16) is of substantially circular cross-section and has first dimensions. The ultrasonic de-coupler (18) which is also of generally circular cross-section and of second dimensions, is connected to and is concentric with the first resonator (16). In use the de-coupler (18) is attached to a bracket (20) adapted to mount the de-coupler (18) onto the frame (12). The first dimensions of the first resonator (16) are such that the resonator (16) is connected to the transducer (T) at an anti-node and the second dimensions of the ultrasonic de-coupler (18) are such that it is connected to the first resonator (16) at a node.
