Unidirectional vibrating screens, forced oscillation type, horizontal and inclined, duly studied and realized by Bernardi Impianti International for the utilization on asphalt plants. The operation is made by means of electric motovibrators with the possibility to vary the amplitude of oscillation through simple adjustments.
The proper design allowed to realize reliable machines with very long maintenance intervals in between; the high efficiency permits the manufacture of simple and neat units, with high capacity and therefore with all advantages due to reduced screening surfaces at same capacity.
