The VB series is made up of vertical vibrators which feature
a double conical flange. These vibrators are typically used in circular screens
and in medium-size and large sieves. They are supplied without eccentric
weights, which must be realised and mounted by the manufacturer of the
vibrating machine. The VB series complies with the most recent IEC and EN
international standards for use in atmospheres with potentially explosive dust
particles. In particular, the VB series can be used in areas 21 and 22.
Technical features
