HOW TO SELECT PROPER VIBRATOR - IN THREE EASY STEPS - A. FIND NEEDED VIBRATOR FORCE FOR YOUR APPLICATION. B. FIND AVAILABLE VIBRATOR MODELS FIND NEEDED VIBRATOR CENTRIFUGAL FORCE (IMPACT) FOR YOUR APPLICATION.

1. BINS, HOPPERS. A.To move the material in a bin or hopper, the friction between the material and bin skin has to be broken. Once this is done the material cannot cling to the bin sides and it will flow out through the discharge. The vibrator force needed to accomplish this, is for 80% of all applications, very simply calculated as follows: Calculatethe weight of the material in the transition or sloping part of the bin. Normally this is the only placce where the friction between the material and the bin sides has to be broken. - DO NOT CALCULATE THe TOTAL WEIGHT, ONLY WHAT IS IN THE TRANSITION PART. For CONICAL BINS, calculate as follows: 261 x dia.2 x height x material density inlbs/cu. ft. 2. FOR OTHER APPLICATIONS CONSULT THE FACTORY

B. When the weight has been calculated, divide by 10 - the figure you get is the force or impact needed on your vibrator. _______lbs. See technical data under "force". For example: The conical part of a 25 ton bin contains 7000 lbs. Divide 7000 by 10, you need a vibrator with 700 lbs. of centrifugal force or impact FInd suitable vibrator on page 4 for VS-380 on page 6 BVS-440. NOTE: Additional considerations when sizing vibrator to bins. 1. If bin side angle is below 30 degrees, select next larger vibrator. 2. If bin thickness is extra heavy select the next larger vibrator. 3. On real sticky and hard to move materials, it is better to use two (2) small vibrators instead of a large one (find the smaller one by figuring half the force needed).
