Applications for 'Sinex' Motor Vibrators -
High performance Sinex motor vibrators find uses in each & ail situations where mechanical vibrations are required. Some of these are Bin discharging; Concrete block molding; Compaction & test tables; Filter bag dedusting;

Separators & screens; Feeders, conveyors & spiral elevators; Seed cleaners, destoners & grading machines; Deburring & vibro polishing mills; Grinding, micronising, mixing & blending machines;, Foundry knockouts and many others limited only by human imagination.


Importance of vibrator selection need not be over -emphasized. However good a range of vibrators available may be, unless a right model is chosen and applied correctly, no good and efficient results can be obtained. Therefore we, Sinex Primemovers, present below at your, our valued customers' disposal, all the data, information and experience gathered during our over a decade long working on this subject.

Industrial uses of motor vibrators could be categorized into 2 types based on amplitudes involved; (I) Tremors -micron level vibrations and (II) Large oscillations, in several millimeters. The former are encountered in silo and bin discharge applications and promoting material flow down chutes, ducts etc. while the later are found in equipment such as feeders, conveyors, spiral elevators, screens, vibratory tables etc..


1). Vibrator Selection for Bin, Hopper & Silo Discharge Applications -
Years of experience and data collection have shown that force applied to bin walls should be 10 to 20% of material weight in the lower convergent part for satisfactory activation, dechoking and discharge.

Formula for material weight calculation : (refer figure-1)
Weight = h/3 [A + a +(A x a)1/2] x BD 'BD' is material bulk density.

Figure!: Positioning Vibrators for Material Discharging
Taking into consideration the above in conjunction with bin sizes and wall thicknesses recommendations are tabulated at table-2 to facilitate easy selection. Since tremors are at high frequencies it is appropriate to use 3000 rpm vibrators hence recommended force values correspond to this speed.
