The oscillating mounting type AB-D of Rosta is the "Price Breaker" among the freely oscillating mountings.
The AB-D oscillating unit is in 7 sizes avialable up to a maximum load of 16,000 N per AB-D.
The pantograph-like construction of the two parallel rubber suspension units gives the AB-D oscillation unit characteristics similiar to the Rosta units AB and AB TWIN. Because of the significantly shorter lever connections (in the double rubber suspension unit), the AB-D oscillating unit offers a much higher loading capacity than the AB for the same compact design. The linear spring deflection under load is still sufficient to assure for this oscillating unit the respectably low natural frequency of ca. 3.2 Hz. At a vibrator or wave frequency of ca. 16 Hz, this is sufficient for a high insulation efficiency of ca. 95%. As with all screening machine mountings from ROSTA, the characteristic of the AB-D assists the linear oscillation motion of the screen.
No lateral guides are necessary for passing through resonance in a controlled manner; the mounting is laterally stable.
