Pneumatic Vibrators
Piston Vibrator Selection
In order to move material in a bin or hopper, the friction
between the material and the bin wall must be broken. Once
the friction is broken, material cannot cling to the sides of
the bin and it will flow out through the discharge. A prime
consideration in selecting the correct piston bin vibrator is
wall thickness. The following formulas calculate material in
the restricted area which is used as a guide to determine the
number of piston bin vibrators necessary.
I Calculate the weight of the material in the transition or
sloping part of the bin. Normally, this is the only place where
the friction between the material and the bin side has to be
broken. Do not calculate the total weight, only what is in the
transition part of the bin.
I For conical bins, calculate as follows:
0.261 x dia. 2 x height x material density in lb/ft 3 (kg/m 3 )
I For rectangular bins, calculate as follows:
Length x width x height x 1/3 x material density.
Chutes
The force required of the vibrator is equal to the weight
of the chute plus vibrator plus maximum material in the
