Bulletin L-EBV
T
he Series EBV Electric Bin Vibrator incorporates adjustable force features
w
ithout creating irritating noise. The low amperage draw at 120V reduces power
consumption and makes the vibrators useable in any application. The EBV
eliminates drawbacks associated with non-adjustable constant force units. The
conventional fix force units are sized with narrow operating limits and may not
move material from bins or pack material in containers if the moisture content
c
hanges. The adjustable force feature increases application flexibility; reducing
e
quipment downtime and labor expense. The EBV is capable of running
c
ontinuously at 100% force output without overheating or mechanical damage.

Installation
1. Before installation, especially if the apparatus has been stored in the warehouse,
remove the side covers from the weights and check to make sure the shaft turns
freely.
2. The EBV electric vibrator can be installed in any position. Fix the electric vibrator
on a rigid area to avoid induced vibrations causing breakage or cracks; if this is not
possible, use plates and ribbing for reinforcement.
3. The mounting surface must be level (max 0.25 mm/ max 0.01 in) so that the
vibrator feet rest uniformly and perfectly in contact with the mounting surface, to
avoid internal stresses which can lead to breakage of the vibrator feet.
4. To mount the electric vibrator, use bolts, nuts and flat washers.
5. Remember that most breakdowns are due to incorrect mounting.
6. Anchor the electric vibrator using a chain with a length and cross section suitable
for supporting the electric vibrator with a maximum fall of 15 cm (6 inches), in case
of accidental detachment.

IBRATION FORCE CALCULATION
F
or Bins and Hoppers:
C
alculate the weight of the material in the transition (sloping part) of the bin or
hopper (not the straight wall above the transition). Divide by 10 and the sum left is
the force needed on the vibrator. For example: if your calculated weight is 1000 lb
divided by 10 equals 100, you will need a vibrator producing 100 lb of force.
For Screens:
1.When vibrating the screen, multiply the weight of material on the screen by two
and the sum is the force needed on the vibrator.
2. Mounting the vibrator on the screen-frame and vibrating both material and frame,
multiply total weight of material and frame by three to get vibrator force needed.
Vibrating Packing Tables:
Multiply total weight of material and carton by two to get force needed.
Centrifugal Force Adjustment
1. Remove the side covers.
2. Unscrew the screws used for locking the movable weight.
3. Bring the eccentric weights to the required value indicated in the following
drawings.
4. It is necessary to make sure the weights are adjusted in the same direction at
both ends.
5. Once the weights are brought to the required value, tighten the bolts to hold the
weights in place.
6. After carrying out the operation on both sides, refit the covers using the same
screws and washers taking care to make sure the gaskets are fitted correctly in
their seats.
