Orton has a wide range of UNBALANCE MOTOR VIBRATORS
to meet the requirement of various industries wherein
material handling plays a major role.
These vibrators help to empty, dose, convey, loosen, test,
clean, screen, compact, distribute, feed etc., &
therefore have a very wide application in Mining,
Fertilizer, Chemical , Pharma & Food Industry etc.
These vibrators are suitable for mounting on bin and
storage silo, vibrating feeders, tables & screens
& many other applications ORTON UNBALANCE MOTOR
vibrators are totally enclosed, surface cooled units
operating 415 / 440 volts, 3 phase, 50 cycles. A.C.
Supply. The vibrating frequency depends on the
revolutions of the rotary unit & can be chosen from
four ranges available viz, : 3000, 1500, 1000, 750
vibrations per minute. The Centrifuge force can be
adjusted from zero to maximum by manipulating the relative
positions of the eccentric weights provided on either side
of the shaft. Various models are available giving a
wide choice of Centrifugal force, frequency of vibration,
mounting position, Insulation etc. The customer is
therefore assured of getting the most suitable vibrator to
meet this requirements.
When used
as a single unit, they impact circular vibrations.
If directional vibrations are needed, two vibrators
running in the opposite direction should be use.

Applications
Unbalance motor vibrators are used where mechanical
vibrations are required. There vibrations can be in
the form of pure rectilinear vibrations for conveying /
screening the material in vibratory feeders / screens /
tables etc. For obtaining rectilinear vibrations,
two unbalance motor vibrators rotating in the opposite
directions are used.

Unbalance motor vibrators
are also used as bin vibrator wherein the hopper / bin walls are
vibrated so as to prevent choking of the material at the discharge
portion of the hopper. The location of the motor vibrator is
extremely important & is generally located in the lower convergent
part of the hopper is as shown in the sketch depicated below. For
such applications, motors with high rpm (approx 3000 rpm) are used as
high frequency vibrations are to be generated. The vibrator
selection depends upon various factors such as wall thickness, weight to
be vibrated etc. Customer to specify inlet & outlet diameter
of hopper, thickness of hopper, height of hopper, material inside the
hopper, bulk density of the material. |
