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.

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.

Large amplitude and low frequency piston types fit in granule with low
specific gravity applied material. It is recommended to use multiple
vibrators in serious clog situations or large tank surroundings.

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=0.2-0.4 GW

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.

MAINTENANCE
Upon final installation of the Series PRV Pneumatic Roller Vibrator, no
routine maintenance is required. A periodic check of the system
calibration is recommended. The Series PRV 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.
