CHUTES
Chutes up to 6 feet (2 m) long are generally handled by one vibrator mounted approximately one-third
of the distance from the discharge. Refer to
Figure 5 . On chutes from 6 to 10 feet (2 to 3 m) long, two
vibrators are needed; one should be placed 18 to 24 inches (46 to 61 cm) from the discharge, and the
other approximately in the middle. Since chutes are very sensitive to vibration, provision should be
made to move the lower vibrator six inches (15 cm) in either direction. This could mean the difference
between moving the material or not moving it.
LOCATING A VIBRATOR ON A CHUTE
FIGURE 5
The vibrator turbine should rotate in the direction of material flow. The vibrator force required is equal to
the weight of the chute plus the vibrator plus the maximum material in the chute.
To move material in a chute, the chute should be inclined no less than half of the "angle of repose" of
the material (at least 10°). If this cannot be done, a feeder is required to handle the material. "Angle of
repose" can be found in most handbooks or easily measured by dumping a cup of material on a table.
The angle the material makes between the table and the cone is the angle of repose.

OPERATION
CAUTION: Do not operate the vibrator while the hopper discharge is closed. This will
compact the contents.
It is not necessary to operate pneumatic turbine vibrators at maximum capability to achieve maximum
performance. Air regulators, timers, etc. should be used to tune the vibration for optimum performance,
save operating dollars, and ensure longer equipment life.
For bulk material handling applications, a pneumatic turbine vibrator should be used to reduce material
friction, not as a feeder. Once particle friction has been reduced, gravity flow occurs and the vibrator
should be shut off. Contents of a bin that is half-full or more will become compacted under continuous
vibration, especially during low discharge rates. This can be prevented by intermittent operation or
cycling of the vibrator. When the speed of the vibrator is cycled from zero to maximum, and vice-versa,
the material resonance is reached, thereby moving the material more effectively than using a
continuous, steady speed. A timer can be used to automatically cycle vibrators. For manual cycling, a
