The screening efficiency of a gyratory screening machine (10), of the type having a moving base (14), is significantly in- creased by mounting to the base a spring/mass system (66, 64) which is tuned so that operation of the machine drive (19) pro- duces amplified movement of the mass (64) along at least one of two perpendicular axes on which the base moves. Movement of the mass (64) reduces the net force on the base along the axis on which the mass oscillates. The reaction force of the machine drive (19) on the base along the other of the two perpendicular axes may be offset by a rotary counterbalance (62) operated by the drive. Movement of the base relative to the ground (15) is thereby reduced, and movement of the screen deck relative to ground (15) is increased. This both increases the effectiveness of the screening motion and decreases the total reaction force transmitted through the base.
