Unbalance Vibratory Motor
Introduction :
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.
