III. Mounting Locations
Install a channel
iron stiffener on
the outside of the
sloping wall
1
⁄
3
the
distance above the
discharge opening.
Multiple Vibrators
Use more than one vibrator when the diameter or
width of any wall is greater than 12 feet (3.66 m).
Always mount the vibrators on different planes.
Two Vibrators on Round or Square Hoppers
Install channel iron stiffeners 180° apart. Install
one vibrator on the outside of the sloping wall
1
⁄
3
the distance above the discharge opening. Install
the second vibrator on the outside of the opposite
sloping wall
2
⁄
3
the distance above the discharge
opening.
Two Vibrators on Rectangular Hoppers
Install channel iron stiffeners on opposite sides of
the long walls. Install one vibrator on the outside of
the sloping wall
1
⁄
3
the distance from the discharge
opening. Install the second vibrator on the outside
of the opposite sloping wall
2
⁄
3
the distance above
the discharge opening. When only one wall slopes,
mount both stiffeners on it. Equally space the
stiffeners on the wall. Place one vibrator
1
⁄
3
above
the discharge opening on one channel iron and the
other vibrator
2
⁄
3
above the bin’s discharge opening
on the second channel.
Three Vibrators
Install channel iron stiffeners mounted 120° apart.
Install the first vibrator on the outside of the
sloping wall ¼ the distance above the discharge
opening. Install the second vibrator on a separate
channel iron at ½ the distance above the discharge
opening. Install the third vibrator on the remaining
channel iron at ¾ the distance above the discharge
opening.
Installation on Chutes and Flow Pipes
Mount channel iron stiffeners vertically or in the
direction of material flow. Center the channel if the
chute is less than 6 ft (1.83 m) in width. If the
chute is greater than 6' in width, use two vibrators
on separate channel irons. To maximize each
vibrator’s radius of influence; center each channel
iron in each half of the chute. Each channel iron
should be located ¼ of the chute width from the
edge and ½ of the chute width apart. (e.g. –
a chute 8' wide, the channel iron locations would
be 2' from each edge and 4' apart.) When wall
thickness is less than ⅛", additional reinforcement
may be required.
