ABSTRACT:
Chatter is suppressed in a solids-liquid separating centrifuge by including, in an external connection to a holder of the speed change gearing between the centrifuge bowl and conveyor, a spring and mass means which is torsionally resilient about the axis of the connection such that it will vibrate about that axis under chatter conditions at the chatter frequency, together with damping means acting in parallel with the spring and mass means to apply resistance to the torsional vibration thereof and thereby irreversibly extract energy therefrom.
