VB
The VB series is made up of vertical vibrators with 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 inter-
national standards for use in atmospheres with potentially
explosive powders. In particular, the VB series can be used in
areas 21 and 22.
Technical features
Power supply
Three-phase voltage from 220V to 690V,
50Hz or 60Hz; suitable for use with an
inverter from 20Hz to the base frequency
with constant torque load profile
Polarity
4 and 6 poles.
Conformity with European Directives
Low voltage 2006/95/EC,
ATEX 94/9/EC.
Reference Regulations
EN 60034-1,
IEC/EN 61241-0, IEC/EN 61241-1
Functioning
Continual service (S1) at maximum decla-
red centrifugal force and electric power.
Intermittent services are also possible
depending on the type of vibrator and the
operating conditions. For detailed informa-
tion, contact our technical assistance office.
Centrifugal force
Proportioned for a centrifugal force
equal to 5000 Kgf. (49 KN), with eccentric
weights not included, to be made by the
user.
Mechanical protection
IP 66 according to IEC 529, EN 60529.
Protection against mechanical impacts
IK 08 according to IEC 68, EN 50102.
Insulation class
Class F (155°C), class H (180°C) on request.
Tropicalization
Standard on all vibrators with “drop by
drop” trickle system.
Ambient temperature
From -20°C to +40°C. Versions for higher
or lower temperatures are available on
request.
Vibrator thermal protection
On PTC rated request with thermistor
heat detectors 130°C (DIN 44081-44082).
Also on request thermistors with different
temperatures and anti-condensation
heaters.
Fixing of the vibrator
In all positions and therefore without
restriction.
Lubrication
All vibrators are lubricated in the factory
and do not require further lubrication if
used in normal operating conditions (“FOR
LIFE” lubricatIon). In heavy duty operating
conditions periodical re-lubrication may
be applied.
Electrical connection box
The size guarantees passage of tools used
for fixing the vibrator to the vibrating
machine. The electrical connection must
be carried out using the relative connec-
tors inserted inside the connection box.
