Vibro Sifter comprises of a specifically constructed motor that is vertically positioned in the center of the screen’s base plate. Between the feeding hopper and the bowl is a screen. The material is fed onto the upper screen’s center. During its journey to the periphery, the undersize substance travels quickly through the screen. The material of its own size is discharged constantly through a tangential exit. This is accomplished through the use of a specifically designed vibratory motor and eccentric Top and Bottom weights.
