Have you ever had someone try to push you over from your side?  I recall skiing with my big brother once when we were kids.  We had gotten off the chair lift and were stopped at the top of a run, getting ready to head down.  I was standing with skis closely together in parallel, hands off my poles as I adjusted my goggles. Big brother gave me a push on my shoulder from the side, perpendicular to the direction of my stance and skis.  I tipped right over.  There was nothing I could do about it.  It was hilarious… at least it was to him and everyone watching me flail about wildly on my way down.  Had I positioned my skis and stance wider and center of gravity lower, I could have avoided this embarrassing failure.

Such is as it is with Rotary Electric Vibratory Motors.  Imagine for a moment that you have a long bar going right through your solar plexus and out of the middle of your back.  Now that you are over that painful thought, imagine that at each end of the bar, there is a weight dangling from rope and swinging around that bar.  Those weights are pushing you in every direction perpendicular to your feet and stance. You are now a Rotary Electric Vibrator! Can’t quite get the mental picture? Check out the photo to the right to see what I am talking about. Read More…

How to Choose the Best Truck & Trailer Vibrator(s) Based on the Material You’re Hauling

Mike Stratis
test

Are you hauling a sticky material, such as DDG or soybean meal, in a hopper bottom trailer? Maybe carrying gravel or asphalt in a dump trailer? What about fertilizer in a v-body spreader?

The reason we ask this information when working with clients is because the material characteristics play a major role in determining the best type of vibrator to help quickly and safely unload the trailer. There is a big difference between unloading sticky DDG’s from a hopper bottom trailer compared to cleaning out the hopper bottom that was carrying whole potatoes or other free flowing materials like corn and wheat.

Installing Vibratory Aids on Equipment: What Are My Options?

David Strong
test

It seems to me that most applications start with a problem to solve; improve a process, simplify an operation, increase yield or throughput, or remove a bottleneck.  This problem could be as simple as placing the appropriately size pneumatic piston vibrator on the size of a hopper.  It could entail getting the right air cushioned vibrator such as the 1200 VMSAC or maybe a single impacting SI vibrator along with the matching SMP mounting channel and controls.  Or the problem could be more broad with concerns regarding the process or task to be accomplished and the design envelope into which the solution must fit and then interface with other equipment.

Regardless of the problem, options and choices are always good.

there’s always a concern of the product discharge height, as the equipment is often feeding material downstream to other devices.  One of the options that impact the design and therefore the height of the unit is the location of the vibrators.  Typically on vibratory feeders and screeners the default Read More…

Tighten Those Bolts!

Mike Stratis
test

If you happened to take the time to read Craig Macklin’s blog, about the expectations for maintenance of the pneumatic vibrators, then you’ll have a good base of knowledge on how to keep those units running efficiently. This time, we’ll take a deeper dive into the importance of tightening the mounting bolts used for installing the vibrators themselves.

On the pneumatic piston vibrators, the proper bolt torque is critical. Because of the tight tolerance held between the outside diameter of the piston and the inside diameter of the bore of the casted body, the vibrator needs to air piston vibrator, nuts and bolts on pneumatic vibratorbe rigidly bolted in place to allow for correction operation so that only the piston is moving inside the vibrator. If the bolts are loose, even slightly, the vibrator body will “rock” back and forth on the mounting channel. Once this starts happening, failures or seized pistons can happen.

Why does this happen? The reason is, the piston will still try to move in a pure linear direction but if Read More…

5 Awesome Things You Need To Know About Industrial Vibration

Katy Sabo
test

Working for the Cleveland Vibrator Company, you can imagine how many times I get the question, “what exactly do you mean by vibrators?” It’s a question I answer with great pride and enthusiasm… and maybe add a little bit of humor for good measure. When I go on to explain just how important vibration is across so many industries, the shock factor withers away and people are engaged in the conversation, wanting to learn more about it. There’s a couple of things you should know about industrial vibration and why it may be one of the coolest fields to work in, here’s the short list to get you started:

It’s Diverse – It’s true. Industrial vibrators can be found on the side of bins, hoppers, silos, barges
and on screening, conveying and compaction equipment. Have you passed a large dump truck lately on the highway? I’d venture to bet there may be a DC vibrator hiding away underneath the body Read More…

Properly Size an Industrial Vibrator on a Bulk Barge Hopper in 3 Easy Steps

Mike Stratis
test

When it comes to unloading dry bulk bins, hoppers or vessels, we all know time is money. The more efficiently a job is done, the more time becomes available to take on new projects. More projects, equals… well, you get it.

One of the options available when it comes to material handling and unloading dry bulk barge hoppers or vessels is vibration. These externally mounted pneumatic or electric devices, when properly sized and installed, appropriately flex the bin or hopper wall to break free rat holing, bridging, caking or sticking material. With the assistance of the Cleveland Vibrator Selection Guide, the vibrator sizing process can be simplified and help increase successful installation. Read More…

How to Properly Clean Fine Mesh Screens Without Damaging Your Equipment

Jeff Hochadel
test

Over the years I have read many articles about how to reduce screen blinding on vibratory screeners. These solutions range from polyurethane balls to brushes. One of the most frequent questions I get asked is how to clean screens once they are blinded for fine mesh applications. Some customers simply throw out the blinded screens or send them back to our rescreening department for a fresh, new screen to be applied.

A screen does not necessarily have to be a very fine mesh in order to blind. We have seen screens with a mesh as coarse as a 2 or 3 mesh can easily blind due to product lodging in the openings while conveying across a screen deck. Of course, the larger the mesh opening the easier the screen is to clean. A fairly larger opening can simply be cleaned from the “bottom side” of the screen surface with a  simple soft wire or hard nylon brush. We have touched on this type of screen deblinding in previous blogs, you can click here to read more about solutions we suggest for these types of screening applications.

On finer wire mesh screens, let’s say 200 mesh and finer, a soft bristle brush may work but you risk tearing the screen surface or worse yet cutting a couple very fine wire mesh thus turning the 200 mesh opening into a much larger sized opening! If your screen frames are small (3”, 8”, 10”, 12”) Read More…

3 Variables to Consider That Influence Material Flow from Vibratory Hopper Feeders

David Strong
test

When it comes to vibratory equipment and end user requirements, Cleveland Vibrator has worked with customers that span the range from simply wanting to move material from point A to point B and they’re not terribly concerned with much more than that goal.  Other customers use vibratory equipment to provide bulk material to downstream processes and are looking for more precise control of the material flow.

Recently I had the opportunity to visit a local customer and assist him with setting up a recently completed hopper-feeder unit.  This customer’s goal was to place a dry material into plastic trays while the plastic trays moved on a conveyor belt under the vibratory feeder.  Precise metering of the dry material into the trays is critical to this customer’s success.  As I worked with this customer and our equipment it seemed to me that this would be an excellent basis for a discussion of material flow and what parameters impact the control of the flow. As mentioned the equipment provided by Cleveland Read More…

The Evolution of Industrial Vibrators: From Pneumatics to Electric Powered Vibrators in the 20th Century

Glen Roberts
test

The Cleveland Vibrator Company started manufacturing air operated vibrators in 1923 and for several years air vibrators is all we pretty much offered. This worked well in our primary foundry customer base through the first half of the 20th century. As we expanded our customer base, we found more and more customers wanting to use electrical power to operate the industrial vibrators. It became obvious that we needed to give our sales staff an alternate source besides air to offer our valued customers.

88-mc-2-electromagnetic-continuous-duty-vibrator-aid-large-chain-of-bakery-plantsWe started with fairly basic electromagnetic vibrators with the MC-1, MC-2 etc. and started to introduce these units into the market place. The MC series is considered the “grandfather” to our current CM-5, CM-10 and CM-30 and more recent Super 30 vibrators. You can see a success story of this product in the field in the case study on the right hand side of this paragraph. In the early 60’s, we contracted with a company from Sweden called Dynapac to market and sell their rotary electric vibrators mostly here in North America. They were supplied in 1800 RPM and 3600 RPM (revolutions per minute) which opened the door to customers having hoppers, bins, chutes, bunkers as well as other applications which include vibratory tables, feeder and screeners.

Air Powered Vibratory Feeders: 3 Things To Know Before Making a Buying Decision

Mike Stratis
test

When it comes to handling dry or semi dry bulk material, there are few means to transport the material from point A to point B. The common options are pneumatic conveying equipment, frequently dense or dilute phase, belt conveyors, screw augers or vibratory feeders, flat pan style or enclosed tube style. There certainly is a time and place for each of these options but we will focus on the vibratory feeder design.

Companies looking to make a buying decision on which type of equipment to install that will handle the material typically turn to the vibratory feeders that are powered by a pneumatic or air piston vibrator for one of or a combination of a few reasons:

cleveland-vibrator-vmsac-vibrator-group-shotAir Powered Feeders Work Well Within a Budget – First, and maybe most importantly, the purchase price. The air powered vibratory feeders can be the low cost alternative to the electromechanical or electromagnetic powered vibratory feeders. The biggest cost savings can come directly from the vibratory drive or mechanism and the vibratory controls. Electromechanical feeders typically have two vibratory motors while the electromagnetic feeders typically have one large vibratory drive attached. Each of these electric powered options require an electrical control box, with dual thermal overload protection for the electromechanical vibratory motors, for on/off operation, speed control or intensity of the vibration control. In contrast, the air powered feeders are driven by a single non-impacting piston, for example the Cleveland Vibrator VMSAC design, units and either controlled by a manual ball valve or 2-way, normally closed, solenoid valve.
