The IFE unbalanced shaft is a well-established and reliable drive for circular motion vibrating screens. The working torque can amount to 19000 kgcm, depending on type. Bearing lifetimes of up to 80.000 hours of operation can be achieved due to the optimized design of the first-class roller bearings and combined oil bath lubrication.

The vibration at 45 to the horizontal produces a satisfactorily rapid advance of the material along the screen. In fact it has been found in practice that the screen will advance the material toward the discharge end even when the screen is inclined so that the discharge end is at a higher elevation than the feed end.

Electric Vibrators and Vibrating Screens In many bulk material processing plants, the material is vibrated because the power of applied vibration energizes material reducing friction against container walls as well as internal particle-to-particle cohesion. As a result, the material moves more freely, feeds more

Dual-shaft screens The drive concept of dual-shaft screens is based on the proven vibration generating system on our circular-motion machines – but in a dual version. Two bearing-mounted drive shafts with unbalance masses are driven in opposite directions. The resulting action of the screen box is thus a linear one, as with geared screens.

The best vibration-reducing material should have vibration absorption capabilities and vibration isolation characteristics in addition to its vibration-reducing qualities. A vibration-reducing material should be able to absorb most of the shock energy while reducing more than half of the vibration energy in a given application.

Eccentric screening optimizes vibrating screens for handling heavy-duty applications, such as classifying and scalping. The eccentric shaft design forces the screen body to follow the shaft movement. While it travels upward, the counterbalance weights move in the opposite direction and create an equal force to that generated by the body.
