A horizontal vibratory centrifuge, which includes a slurry separating component; a drive motor; a drive unit for rotating the separating component; a feed pipe for feeding the slurry into the separating component; a product discharge for discharging the solid portion of the slurry from the separating component and a pipe for discharging the fluid portion from the separating component; at least one vibratory motor mounted onto the drive unit; a plurality of connecting rods moveably connecting the drive unit to a torsion bar assembly, the assembly including a plurality of torsion bars, each mounted on a first end to an upper fixed spring clamp and a lower fixed spring clamp, and on a second end to the connecting rods with bearings, so that the vibrations of the low energy vibrating motor is in resonance with the springs so as to provide in part maximum vibration to the vibrating assembly at low energy levels. There is also provided the method of imparting vibration to a slurry in the separation component by a single low energy vibrating motor which operates in resonance with the torsion springs to achieve maximum vibration and thus maximum separation between the solid and liquid components of the slurry.
