Undermill Oscillators & Vibrators

Downstream of the Shredder, the first component is generally an Undermill Oscillator (“UMO”) or Vibrator, which is designed to meter the shredded material onto conveyors with a constant homogenous flow. This component must be highly abrasion resistant and able to handle constant shock load and frequent explosive forces. UMOs are “positive displacement” devices that use a Camshaft Drive, which in turn transmits a high amplitude low frequency motion through Rocker Arms & Reactive Coil Springs. Vibrators are “passive displacement” devices that have an eccentric weighted motor (or motors) mounted under the Vibrating Deck and sit on Isolation Springs. These units generally operate at a higher frequency. Vibrators are commonly used at the Magnetic Separator area and in the Non-Ferrous process area.
