The STE screen is four bearing so the rpm and stroke remain the same regardless of strain. This provides a consistent screening result and a predictable behaviour, but when conditions change a need for calibration often occurs, e.g. when material freezes in the screening box or meshes are swapped from lightweight to heavier. Counterbalancing is however never more needed with the new Vibro Block edition.
Prevent vibration damage
With the Vibro Block concept the screen box is mounted on a vibration damped frame which prevents the vibrations from the screen from transmitting to the chassis. This saves the entire plant from damages caused by vibration, whilst the screening motion remains efficient. The Vibro Block design allows the STE screen to operate with the capacity of a four bearing screen as smooth as a two bearing screen.
