  • Vibrating centrifuge
    Patent number: 8813974
    Abstract: A vibrating centrifuge having a separation screen that is rotated and vibrated to separate a material, typically slurry (e.g. coal slurry). The separation screen is vibrated by a vibrator, such as an unbalanced motor. One or more constraint members, preferably leaf springs, are provided that restrict vibration generated by the vibrator to a single degree of freedom that is parallel to the drive shaft axis. The vibrating centrifuge has a biasing member in the form of a compression spring to tune the vibration frequency. Optionally a tuning mass can also be used to tune the vibration frequency.
