FEATURES

• The body is made of high strength aluminum alloy.

• Small in size and light-weight.

• Can be used in high humidity or dusty working areas.

• Frequency and amplitude of vibration can be adjusted as needed.

Series BPV Pneumatic Ball Vibrators are the best choice for bridge­break in thin walls and small tanks. This model can be used in vibrating
separators, vibrating conveyors, and against electroplating build-up. It
can also be used on material compacted while packing or sand
compacted while molding.

HOW IT OPERATES

The aluminum body is equipped with a steel ring and ball inside that is
tightly closed by plastic side covers. Vibration is caused when the
internal ball, pushed by compressed air, runs in a rotary motion to
produce centrifugal force.

INSTALLATION

Vibration force transmits more efficiently in a conical hopper tank as
opposed to a rectangular hopper. It is recommended that you install two
vibrators in rectangular hoppers.

1. Vibrator force can be transmitted more efficiently by using “U” shape
steel supports. It can help materials run smoother in the tank or pipe. It
also reduces tank damage accidents.

2. To avoid tank wall amplitude caused by the vibrator moving in a left or
right direction, use “U” shape steel.

3. Reinforced board is required between “U” shape steel and a thin tank
wall.

4. To increase vibration fields in a big hopper tank, criss-cross “U” shape
steel.

Attention: Vibration has to be fixed by a high tension bolt, washer, and
spring washer. Connect with a security cable if the vibrator is installed
onto a hopper.

VIBRATION FORCE CALCULATION

Taking the accumulated situation into consideration, the appropriate
vibrator will give 0.2~0.5 G accelerated vibration onto the target object.

F=0.2-0.4GW F: Vibration force (N)

G: Acceleration of gravity
W: Material weight (KG)

MATERIAL WEIGHT CALCULATION

Generally speaking, the hopper portion of the tank should be taken into
consideration.

Notes: Various tanks are based on application requirement. Customers
choose appropriate vibrator types to meet with various applicant demand
(tank shape, material, applied material, etc). Suitable vibrators will not
only prevent obstruction problems but won’t damage the tank walls.

MAINTENANCE

Upon final installation of the Series BPV Pneumatic Ball Vibrator, no
routine maintenance is required. A periodic check of the system
calibration is recommended. The Series BPV is not field serviceable and
should be returned if repair is needed (field repair should not be
attempted and may void warranty). Be sure to include a brief description
of the problem plus any relevant application notes. Contact customer
service to receive a return good authorization number before shipping.
