Vibrator performance, force output, frequency, energy consumption and noise, all parameters that are of interest to our customer to some degree or another. At one end the spectrum we might have a plant maintenance supervisor who simply needs a vibrator as a flow aid on a hopper and isn’t particularly interested in the exact operating frequency and force output of the unit, just needs something that works, solves the problem. On the other end of the customer range is the user who wants to know force and energy consumption at a specific frequency. Vibrator sizing on hoppers as a flow aid is driven by the physical characteristics of the hopper and the material stored in that hopper. Read More…
Recently, I took a whirlwind trip through the heartland. During this trip, I had the opportunity to visit plants and equipment makers installing and using vibrators. While in the field, I encountered damaged equipment, including cracked hopper walls that had to be re-welded.
Too often, the vibrator gets a bad rap in these situations. However, in reality, the damage is a function of incorrect sizing or installation of the vibrator. So to clear up any misconceptions, here are three easy recommendations to prevent future equipment damage:

There are a wide variety of vibrating tables available to pack material in containers. Flat vibrating tables or packers are commonly used for this application where an empty container is manually placed on the table, filling begins, at some point during the filling process the vibrating table is started to begin packing and finally you end the filling cycle and turn off the table. While this manual operation fits the needs of many operators, they may not be aware that there are alternatives that allow a more automated operation. Read More…

We were contacted by a company that performs a special process on large diameter copper bars. Part of the process is seating the copper bars in place to do the process. This is currently accomplished by hitting the bars with an 8 to 12 pound sledge hammer. Due to the taxing and power-filled motion of the hammering process, it was causing extensive shoulder and back injuries on their employees. The situation was dire enough that it required a call to action and a solution, so they contacted The Cleveland Vibrator for a vibrator recommendation. Read More… Share this blog post:
Well, this sad news was released recently: “Worker Engulfed in Rail Car…” which made me revisit my prior post to dig into data some more. Once again, I went to the data set provided by NPR Buried in Grain. This time I looked only for “rail car” in the incidents and found two in the data set. While the two incidents in the data set both correspond to workers trying to clear clogs while unloading the rail car hoppers, this new incident does not. Its cause was related to the worker slipping and falling while loading the car. Either way, these incidents are terrible, tragic and preventable with proper safety precautions and training. Rail car vibrators are one tool to help prevent bin or hopper entry during unloading. I encourage anyone following these continued incidents to look into resources available from organizations such as the Grain Handling Safety Coalition.

Like a lot of companies we talk a lot about customer service and going the extra mile when particular situations arise. Last week we had just one of those situations involving one of our larger RE 80-6 Rotary Electric Vibrators. The customer was in Texas and had a vibrator go down on a large de-watering screener. Fortunately, they had followed our suggestion and purchased a spare backup drive. They now wanted to order a replacement for that one but we had just recently sold all of our stock in that size to one customer. The drives are used on a critical piece of production equipment and could ill afford having a second drive go down.
With no spare available, we looked at up-sizing but mounting bolt centers would be a problem. We looked at different RPM motors with same bolt centers but after consulting with our equipment “GURU” Read More… Share this blog post:
Vaccum Mount Series explains features and what sets Cleveland Vibrator above the rest – See it in action here!
Most everyone over, say, 25, knows that time seems to escape you way faster than you’d like. That certainly happens here at Cleveland Vibrator – you turn around and another year or two is gone and you wonder what the heck happen to it. I really felt that way here recently as we just finished up work on a new product. Sales has been pushing for a “Vacuum Mounted Vibrator Series” for a while now and I’m happy to say we’ve just completed work on the mount and controls for our 1200 VMSAC, air -cushioned piston vibrator and the smaller 1125 VMSAC.
I’ve been told that my last blog regarding the importance of wall thickness when utilizing external industrial vibrators for bins or hoppers seems to have struck a chord. I plan to expand on that blog by providing some recommendations for sizing external vibrators since I merely referred to a vibrator with proper force previously – and you just may have been afraid to ask!
Essentially, we need to apply enough external force to the wall of the bin or hopper to assist gravity in getting material to flow. While I previously stressed properly flexing of the wall to get the material to flow, we still need to determine the correct amount of force to apply based on the configuration of the hopper as well as the bulk density and flowability of the material.

“What’s the amplitude of that industrial vibrator?” – I hear this question more often than one might think.
You’d think it’d be a simple question to answer. But, with industrial vibrators, it just doesn’t make sense and isn’t relevant to most applications. In my book, no vibrator has “an amplitude.” However, without a doubt, each vibrator model has unique performance characteristics that we can measure and record.
1200 VMSAC on pellet mill station bin
Once we understand the requirements for the application, like a vibrator on a bin or hopper to assist in material flow or mounted on a piece of equipment, the vibrator performance characteristics help our sales and engineering staff make the best recommendation for optimal performance. But you can’t say, “I need a vibrator with an amplitude of X,” and get several options.
What structure characteristics affect the amplitude of vibration?
When you start thinking about the amplitude of movement of anything with a vibrator attached to it, you’ve got to ask yourself several additional questions:
What’s the weight and wall thickness of the structure?
Is there isolation involved or is it rigidly fixed to a support?
Is the goal to move or compact material or just introduce “movement” in a section of the structure?
With vibrating equipment, it is relatively easy to calculate the expected “amplitude” of the finished unit while we’re still in the design phase. Using solid modeling, we have a good sense of the weight of the unit. Put this together with the performance parameters of the vibrator and we can accurately predict the expected amplitude of the finished unit. Take the weight of the unit, frequency of the vibrator, and its known force, toss in a conversion factor, and you can kick out a decent estimated amplitude of the completed assembly. This helps us predict the performance and capacity of the equipment, be it a feeder, screener, or compaction table.
What factors does the amplitude of vibration depend on?
When asked, “Hey, what’s the amplitude of the 1200 VMSAC Pneumatic Vibrator?” you can’t fire back, “Oh, it’s 0.157 of an inch”. Unfortunately, it just doesn’t work that way. Amplitude is not an independent parameter of the vibrator. Amplitude depends on two factors:
The structure to which the vibrator is mounted
The freedom of movement of that structure
What hopper characteristics are important for industrial vibrator installation?
Frequently, the customer is trying to improve bulk material flow in a storage container. Typically, the amplitude of the vibrator doesn’t solve bulk material flow problems. Over the company’s history, The Cleveland Vibrator Company has developed sizing charts and guidelines for hopper applications; this involves the characteristics of the hopper, including the following:
Hopper wall thickness
Volume of the hopper
Sometimes material type, if it is difficult to move or sticky
I can’t recall anyone in sales or engineering telling a customer they need a specific vibration amplitude. There are times when the nature of the material will lead us to recommend a “larger stroke or amplitude.” With rotary electric vibrators, this translates to a lower frequency vibrator, resulting in larger vibration amplitude. Given the same force output, a slower frequency vibrator will produce a larger amplitude or stroke when compared to a higher frequency vibrator on the same structure.
Turbomite Turbine Vibrator
As a side note, this relation leads to one of our primary design considerations for our Turbomite Pneumatic Turbine Vibrator line. You will notice we produce forces similar to our competitors at much lower frequencies.
The application of industrial vibrators is rarely an exact science – here’s how we can help!
There are many years of experience here at The Cleveland Vibrator Company. Folks have seen and heard about hundreds, if not thousands, of applications over the years. But what keeps things interesting is the challenge of a new application where you need to explore your options.
We can reach back into the knowledge base and make a good recommendation more often than not. If that doesn’t seem to be the best route, we can generate a computer solid model and run an FEA analysis. This may give us a better prediction of the amplitude of a vibrator-structure assembly. But let’s not use that approach to apply a VM-25 Air Piston Vibrator on a thin-walled hopper section. It’s probably more cost-effective to simply buy one and try one! On the other hand, you could always ask about our 30 day trial period.
