Vibrating conveyor and separator apparatus (10) is disclosed in which the sum of the momenta of the reciprocating components is minimised and the sum of the kinetic energies of the reciprocating components is substantially constant throughout the vibration cycle. This is achieved by the use of a pair of counterbalances (16, 17) vibrating in the same direction as the conveyor (11), but with phase differences and amplitude ratios relative to the conveyor (11). The counterbalances (16, 17) are vibrated through greater amplitudes than the conveyor (11), allowing counterbalances of smaller mass to be used. The apparatus does not rely on springs for energy storage and is therefore not confined to operate within a narrow range of speeds close to the natural frequency of a spring/mass system. |
