How Vibration Helps Improve Dust Collection Systems

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. These filters rely on an electrostatic charge to pull dust particles from the air passing through the collection system. To help the efficiency of the collection of the dust, keeping these wires and plates clean is imperative to the process. This is where a Rapper comes into play. The Cleveland Vibrator 3” PMA Rapper is an air powered piston vibrator that is installed on a mounting plate connected to a shaft to shake the wires and plates. This shaking process breaks the friction of the particulates clinging to the collection media and drops the dust down to the collection hopper underneath. Once the materials is in the collection hopper, an externally mounted piston vibrator or air knocker can help remove the dust from the inside sloped walls of the hopper and to the discharge.

For a helpful visual aid, check out this video on YouTube courtesy of Thermax Global.

For the baghouse collectors, many of them use pulses of air to clean out the hanging bags on the inside of the system to drop the particulate down to the collection hopper below. Once the material reaches the collection hopper, single impact air knockers or piston vibrators can help clean off the inside sloped walls of the hopper to ensure material reaches the discharge outlet or the feeder underneath.

For a video to see this in action, we can thank the people at Astec for putting together this YouTube clip.

Lastly, the cyclones. These systems rely on the shape of the vessel and the directional flow of air pushed into the vessel to spin particulate and create a vortex. The gravity of the particulate helps this material drop to the hopper underneath while the cleaned air, which is lighter in density, exits the exhaust vent at the top of the collector. Similar to the baghouse process, once the dust reaches the hopper bottom, a single impact air knocker or piston vibrator can help move that material out of the hopper and to the discharge below.

Our friends at Aerodyne have posted this video on YouTube to give a demonstration of a cyclone working.

One of the biggest keys to longer lasting equipment is proper maintenance. Installing a rapper or air knocker or piston vibrator can help keep the collectors clean and running as expected.

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…

Truck Vibrators – What Are The Options?

Mike Stratis
test

When it comes to unloading dry or semi-dry bulk materials from a hopper trailer, belly dump, side dump, end dump or similar type of truck, there are a few vibratory options available to the market. Depending on the power supply available on the mobile equipment, air or electric, the vibratory components change. We will first look at the air powered vibrator options then turn to the electric powered vibrator options.

The pneumatic or air powered units that are available are the piston style vibrator or the turbine style vibrator. These two are by far the most common air powered vibrators found on mobile equipment. The Cleveland Vibrator Vibra-Might air piston vibrators are popular units in the field. These vibrators have a dual diameter piston which allows for start up at any mounting angle and there is no spring on the inside of the vibrator. No spring equals less wear parts. These vibrators also have a single exhaust port and come standard with the exhaust port protector. The exhaust port protector helps keeps dust, dirt, water and other contaminants out of the bore of the vibrator. These Vibra-Might air piston vibrators come in both 4-bolt square base and 2-bolt rectangular base designs. Read More…

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…

Niche Business, It’s What We Do

All organizations that have stayed in business for many years have “go-to folks” they depend on when difficult situations or tough problems arise that need to be taken care of. For example, how many times have we watched a football game and experienced the quarterback take his team 90 yards in under two minutes to win a game or the linebacker or safety make that key tackle or interception for a last minute victory? If you root for every team but the Browns, we’re sure you’ve experienced this enough to know the importance the role these key players fulfill. These are go to folks and it is no different in the business world, especially here at The Cleveland Vibrator Co.

I think we are blessed with several go to folks on our team. When a customer calls Cleveland Vibrator, they are not just talking to a sales associate but to engineering, manufacturing, purchasing, marketing, shipping and yes, even our owners from time to time. I believe this collectively makes Cleveland Vibrator a “go to company” for many special applications. I call this our “NICHE” business and feel it has been one of Cleveland Vibrator’s strengths, even before I was given the opportunity to join the team in 1968.

Things to Stick a Vacuum Mount Vibrator On, Part 1

Craig Macklin
test

Recently, Cleveland Vibrator Co. has been working on developing a series of Vacuum Mount Systems for our vibrators.  Typically, these are used for helping flow or clean out on portable hoppers, bins, IBCs, hopper bottom and belly dump trailers, or railcars.  However, our newest release, the Mini Turbine Vacuum Mount series, has a variety of other fun applications that we can demonstrate in our very own plant here.

The first application to look at here is the Vacuum Mount CVT-P-20 being used in our coil making process.  Our line of CM Electromagnetic Vibrators uses encapsulated coils that we make in house.  In that process, we use vibration in order to settle epoxy around the coil in a mold, removing air bubbles and eliminating voids.  Typically, we have used our VJ Vibratory Jogger tables in order to do this.  However, in the video linked here, you can Read More…

It’s Halloween… Tales from a Small Town Boy Will Have You Shakin’ in Your Boots

Glen Roberts
test

With Halloween approaching fast, it has reminded me that over the years Cleveland Vibrator has sold several vibrators to entertainment enterprises for use on their Halloween projects. One of these projects, I was told, was for a Haunted Mansion Halloween Party for a pretty well known publication here in the U.S. (*Mansion may be a pretty big clue here). They used two 1125 VMS Air Piston Vibrators mounted below the floor to surprise folks as they walk on them. We even built an “Earthquake Machine” for the Natural History Museum here in Cleveland, Ohio to give visitors the experience of what an earthquake may feel like. They even covered the drive motors so you could actually sit on them. This holiday also brought back an experience I had at a burial vault company visit just a few years past. But, before I tell this story would like to explain what led up to my reaction to this visit.

I think that our beliefs and fears about Halloween go back to what we have learned or were told as kids. This for sure applies to my background as a youngin’. I was raised in Southern Ohio on a small farm that had no phone service until I was twelve or thirteen. Read More…

Sand Isn’t Just For Beaches…

The sun is shining, the ocean waves are crashing down, and I am enjoying a book on Hilton Head Island… OK. SNAP BACK TO REALITY. Living in Northeast Ohio, one could imagine our winters are long and summers fly by quicker than we can blink. Beach daydreaming is a favorite pastime of mine but also inspired me to right a little blurb about a visit made to a customer right here in Cleveland who deals with that soft every day of the year. The visit gave me a little taste of that soft sand between my toes, literally…

No, I wasn’t lounging in my beach chair, but instead hiking up on top of sand filled silos and learning all about what exactly sand is used for in day-to-day life. One of our fantastic customers invited myself and Glen Roberts to come out and see our Rotary Electric Motors in use on their chutes they use to keep bulk sand flowing through it’s heating, cooling and separating process. If you have read any of my previous blogs, you would know I am a complete sucker for history and find it fascinating to learn all about different processes and how they have evolved over time. This facility we visited was no exception. This plant has been located right off Lake Erie since the 1940’s and has original sand at the bottom of its silos since it’s opening day still present today.

Our trip was quite eye opening and once again, I was completely awestruck over the idea that such a simple material I have played in since I was a kid, played a major role in creating everyday items. We learned there are three different “grades” of sand all serving specific end product use. Read More…

Unique Vibrator Installations & 5 Ways To Repair Damaged Walls

Glen Roberts
test

Over the past 90 years that The Cleveland Vibrator Company has been in business, we have been a part of many vibrator installations on hoppers and bins. One of our major markets  is supplying industrial vibrators to the feed and grain industry. I have spent some time in the past years talking to and visiting folks who are responsible for making sure their facility operates in an efficient manner with minimal down time. One of the more unique scenarios I have noticed is the many different ways the vibrators are mounted to the bins and hoppers. More particularly, I have given more attention to the different types of channels and mounting brackets used and how they are secured to the bins.

The great part about many of the installations that I have seen is that though they may not fit the standard mounting practices we typically recommend in our installation manuals, they still get the job done. In most cases we suggest to mount the vibrators on the sloped section of the hopper or bin and locate it about one-third of the way up Read More…
