Abstract
A vibratory apparatus including a trough having one or more decks, with an inlet end and an outlet end, a first plurality of isolation springs disposed between the trough and ground, and a two-mass, sub-resonant frequency exciter supported on the trough. The trough and the exciter move 180-degrees out of phase with each other. The apparatus also includes a dynamic balancer including a plurality of isolation springs disposed between the exciter and ground.

A vibratory apparatus, comprising:
- a trough having one or more decks, with an inlet end and an outlet end;
- a first plurality of isolation springs disposed between the trough and ground, each of the first plurality of isolations springs attached at a first end to the trough and at a second end to the ground;
- a two-mass, sub-resonant frequency exciter supported on the trough, the trough and the exciter moving 180-degrees out of phase with each other;
- and
- a dynamic balancer comprising a plurality of isolation springs disposed between the exciter and ground, the plurality of isolation springs of the dynamic balancer being different from the first plurality of isolation springs and each of the plurality of isolation springs attached at a first end to the exciter and at a second end to the ground.

A vibrator, apparatus, comprising:
- a trough having one or more decks with an inlet end an outlet end, and a longitudinal axis that extends from the inlet end to the outlet end, and first and second sides parallel to the longitudinal axis;
- a first plurality of isolation springs disposed between the trough and ground;
- a two-mass, sub-resonant frequency exciter supported on the trough, the trough and the exciter moving 180-degrees out of phase with each other,
- the exciter being supported on the first and second sides of the trough, and the exciter having first and second sides parallel to the longitudinal axis;
- a dynamic balancer comprising a plurality of isolation springs disposed between the exciter and ground,
- the plurality of isolation springs of the dynamic balancer disposed outwardly of the first and second sides of the trough relative to the longitudinal axis and outwardly of the first and second sides of the exciter relative to the longitudinal axis in a transverse direction;
- and
- a frame disposed on the ground outwardly of the first and second sides of the exciter relative to the longitudinal axis in a transverse direction, the exciter having mounting brackets disposed on the first and second sides, and the plurality of springs disposed between the frame and the mounting brackets to couple the exciter to the frame.
