How Vibration Helps Improve Dust Collection Systems

Mike Stratis
test

When it comes to collecting dust created from a production line at a facility, it is critical to clean the existing and recently collected dust out of the collection equipment on a regular basis. One of the methods to remove the collected dust is with the help of vibration. Where the vibration is applied, though, depends on the collection system installed. The common installations that we see are:

• Electrostatic Precipitators (ESP)
• Baghouses
• Cyclones

First, the electrostatic precipitators. These are large systems that are frequently found at facilities like pulp and paper or steel mills, refineries, concrete plants or coal-fired power plants, just to name a few. These systems have a series of wires and plates that act as filters. Read More…

Tighten Those Bolts!

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…

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…

What to Expect for Maintenance of Pneumatic Vibrators

Craig Macklin
test

As my incredibly knowledgeable associate Mike Stratis just provided a posting about accessories to consider for your installation of a pneumatic vibrator, I thought I would provide a follow-up piece to discuss what to expect AFTER the install. As with any equipment, pneumatic vibrators and their supporting accessories do require some love, attention, lubrication and cleaning from time to time. Here is what to expect if you want to get the longest and most consistent life out of your pneumatic vibrator, whether a piston, turbine or ball.

Air Piston Vibrators 

Cleveland Vibrator Pneumatic Piston Vibrator Group ShotLubrication – First and foremost, check your lubricator with some frequency.  If you operate continuously, you might check and/or refill every 1-3 weeks.  If your use is intermittent or infrequent, you might schedule on a 1-4 months.  The use of internal coating in the vibrator can reduce or remove the need for lubrication.  But, coatings without the use of lubrication will typically wear out faster than a coated or uncoated piston vibrator that is properly lubricated.  Depending on size and duty cycle of your vibrator, you might use a pint of lubricant (we recommend our MXR-12 VibraLube, which is 10W-NR) every 2 weeks to 2 years.

What Are the Costs Associated with Installing Pneumatic Vibrators?

Mike Stratis
test

When it comes time to review solutions to the material flow problems inside the hopper, pipe or chute, there are a few things to keep in mind when putting together a budget for the project. Besides the vibratory flow aid itself, there are additional components required before installing the unit. We will discuss these items and estimated costs to acquiring these components. Here is the short list:

  1. Industrial Vibrator – pneumatic piston vibrator, single impact air knocker, pneumatic turbine vibrator, pneumatic ball vibrator
  2. Safety cable
  3. Mounting channel or plate
  4. Hose to connect vibrator to on/off valve
  5. On/off valve
  6. Hose to connect on/off valve to air prep component (filter/regulator or filter/regulator/lubricator)
  7. Lubricant (if necessary)

Depending on the size of the hopper or piece of equipment that the pneumatic vibrator is going to be installed on, the price of the vibrator itself can range from about $100 to as much as $10,000. But, within that range, vast majority of the units are going to be between $100-$1000. Read More…

Vibrator Coating Testing Results: Only Time Will Tell

David Strong
test

Some time back in the mid-60s Cleveland Vibrator started working with coating technology in an effort to improve the performance and longevity of our line of pneumatic piston vibrators.  For best operation while consuming a minimum of compressed air, the piston and the body of any pneumatic piston vibrator need to be very closely matched.  Clearance between the moving piston and the fixed body is very fine, in certain installation orientations the piston rides on the body of the vibrator creating a metal on metal contact area.  Because of the metal on metal contact it is recommended to supply a pneumatic piston vibrator with lubricated air.  The appropriate amount of oil mist in the air stream will lubricate the moving parts, reducing the co-efficient of friction between the surfaces and extend the life of the vibrator.

Cleveland Vibrator’s investigation into and early use of friction reducing coatings was designed to leverage the benefits of the coating to enhance the performance and extend the life of the vibrator by reducing parts wear due to friction.  If not properly maintained and lubricated a piston vibrator will start to wear due to the piston/body surface contact.  Indicators of excessive wear will be reduced performance, less force output and more air consumed at the same operating pressure.  As the piston and body wear over time the gap between the two parts will increase, with the larger spacing air can “blow by” the piston, blow by air isn’t effectively used by the vibrator to generate force it simply exhausts out of the body.  Read More…

Cleveland Vibrator recently added a new employee in the Fabricated Equipment area of the company.  At the end of 2015 our CEO declared that 2016 would be a “year of investment” here in terms of both people and equipment.  It’s exciting to see this sort of thing happening, good people coming on board as well as some new CNC equipment on the immediate horizon.  It all makes Cleveland Vibrator a better company.  While getting to know a bit about our new guy in the Fab area, we talked some about his work experience and the opportunity at Cleveland Vibrator.  One of the things he already likes about the position is that he gets to see a piece of equipment completely manufactured, start to finish.  I told him that’s one of the things that I’ve always enjoyed about my job, getting to be involved with the complete process often starting with the solution concept generation phase to final testing of that solution prior to it shipping out to the customer.

I think most engineers are problem solvers and that’s one of the aspects of this profession that they find interesting and rewarding.  That’s certainly the case for me.  I’ve always found the diversity of Cleveland Vibrator’s customers and their problems very interesting.  Plus, I feel that we have a very “intimate” manufacturing process, it’s all here in one location.   Whether it’s the manufacture of a pneumatic piston vibrator, as an example the 1300 VMSAC, air cushion vibrator piston vibrator or a large vibratory feeder Read More…

Sizing and Selecting Air Piston Vibrators for Conical Silos

Mike Stratis
test

When turning to a pneumatic piston or air piston vibrator for bin clean out or bulk material flow out of your material storage vessel with a conical transition hopper, there are a few things we review to help determine the best unit for the job. Here are the various sets of criteria we review before making a recommendation:

  1. Find number of vibrators needed
  2. Find strength of vibrator needed
  3. Find best air piston vibrator for application

Step One: Find the Number of Vibrators Needed

To find the number of vibrators recommended for the conical hopper, we look at the geometry of the vessel being vibrated. The geometry, size and shape, of the vessel tells us the number of vibrators needed for the most effective vibration transfer into the material. There is about 5 feet of effective radius for the vibration energy from where the vibrator is mounted. Here is a visual aid which allows you to see how many vibrators are needed based on the size of your hopper. Read More…
