Vibratory Compaction Tables: 5 Things to Consider When Working Within A Budget

Mike Stratis

Are you looking to add a vibratory table to the manufacturing and/or shipping processes of your facility? If yes, great! We’d be glad to help put our experience to work and point you in the right direction. There are a few things to review during the buying process and each of these forks in the road can have an impact on overall cost of the equipment.

For starters, what can vibratory tables do? We commonly see the following reasons to include a table:

  1. Flatten the mound build up or pile of material made from the filling station discharging into center of the Gaylord, tote, box or similar type packaging container
  2. Compact and stabilize bulk bags, FIBCs or super sacks for easier stacking and handling prior to storage or shipment
  3. Fully or semi automate packaging lines by integrating with rollers sections (CDLR and gravity) or belt conveyors
  4. Fill, weigh and compact material
  5. Remove air bubbles in molds and casted products for improved structural and surface finish
  6. Lower labor hours and costs for packaging and processing lines

Unique Design Options Available for Specific Vibratory Compaction Table Applications

David Strong

Recently on a long weekend I took the “Behind the Scenes Tour” of the C.F. Martin guitar factory in Nazareth, Pennsylvania.  During the tour the six of us in my group got to see pretty much the whole guitar building process from wood coming in the back door to final set up of the completed instrument.  Along the way we spent a few minutes talking with the guy that actually hand selects the wood for all the Custom Shop guitars, the customer works with a Martin guitar distributor, customizes an instrument and starts the process.  This gentleman reviews the order’s specifications and gets to look through Martin’s selection of some of the most beautiful wood you’d ever want to see to find just the right set to match up with the order.  Custom shop orders start with the basic guitar body style and build on from there, sort of like what Cleveland Vibrator does with its product line.  Cleveland Vibrator is very customer driven; the customer knows their business, process and goals, Cleveland Vibrator asks questions, listens, and often conducts testing, then offers a solution to accomplish those goals.  Similar to Martin Guitars on the “custom build your guitar” portion of their website, modifications to Cleveland Vibrators products is available.

FA Flat Deck Vibratory TableA good example of a product that is often modified by customer requirements is the vibratory table.  Basically a table is designed to vibrate linearly in the vertical direction.  From this very basic concept there are almost an infinite number of options and variables available to accomplish the customer’s goal, regardless of how simple or Read More…


2015: The Year of the Vibratory Table

Katy Sabo

With a new exciting year in sight for me here at Cleveland Vibrator, I took some time to reminisce on some of my favorite FAB jobs that headed out of our facility throughout 2015. As I was perusing through my photo files, I found that our Vibratory Compaction Tables dominated this past year with our Vibratory Feeders running a close second. If you have read any of my other blogs, you will know that one of my favorite obligatory duties around here is filming equipment for quality assurance purposes before it leaves our manufacturing plant. Moreover, I love learning about new applications which our equipment will be used for and let me tell ya’, there were some pretty fun ones this year. So let’s take a trip down memory lane and get us stoked for the upcoming year folks!

At the beginning of last year, David Strong, Jack Steinbuch and myself took a maintenance visit to a customer right here in Cleveland to see one of our flat decks in the field. Read More…


Cleveland Vibrator and the Chocolate Factory

Katy Sabo

Anyone who knows me well, knows about my undying love for chocolate. I had a great aunt who lived 98 wonderful, rich years and was quick as a whip until her final days… so what was her secret? A piece of good quality chocolate a day will let you live long and prosper. I will never forget that and have adopted that mantra. Since I began working at Cleveland Vibrator over 2 years ago (wow times flies!) I have seen how industrial vibration mixes with some of my favorite things in life. One of which, if you haven’t guessed already, is chocolate.

I was perusing through our case history archives last week and found one dating back to the 1960’s where industrial vibration was being used in a leading candy producer’s factory. Their chocolate molding department was encountering an air bubble problem in their molds during the filling process, Read More…


It’s Complicated, or Is It? The Frequency, Stroke & Acceleration Relationship

Jack Steinbuch

Variable Frequency Drives (VFD) have become commonplace in many of our bulk material handling applications due to the adjustability they provide and the cost which has become more attractive over the years.  However, I have found that many of our customers do not understand what they can achieve with this controller and how it affects acceleration when working with our electromechanically driven equipment featuring twin electric motor vibrators like our EMF vibratory feeders, EMS vibratory screeners and FA flat deck & GT grid top tables.

So we will start off with the fact that is contrary to what some might think – the lowering of the frequency does not affect the stroke being produced by the equipment.  The stroke of the equipment can only be changed by mechanically adjusting the eccentric weight settings on the vibrators.  Read More…


3 Ways To Measure The Strike Force Of A Pneumatic Vibrator

David Strong

Recently the sales team forwarded the following question from a customer –

“We use some of your impulse piston vibrators to fill molds with powder. Do you have a recommendation for a way to measure the strike force such as a G-force meter or Accelerometer? Any ideas you have would be greatly appreciated.”

This seems like a pretty straight forward question but upon closer inspection, it gets a bit more complex.  So let’s break it down and look at the pieces of the question.  It’s always important to make sure we’re on the same page in our understanding of the question and terminology used.

Brake. Don’t Break.

Craig Macklin

To the casual observer, Vibratory Equipment might look like pretty simple stuff.  You just slap some vibrators on the thing to make it shake, right?  Anyone can make that!  Well, as we’ve seen in some other detailed posts from Jack Steinbuch and David Strong, there is more than meets the eye to designing and building something that will work and last.

One design feature in our controls that we have offered and recommended in the past is the Dynamic Brake. I say that we offered in the past because we are now moving to just making Dynamic Brakes standard features.  We recognize that many folks may not know what a Dynamic Brake really does in order to see it as a good option to add.  However, as you will see in the explanation and video here, it is more than a good option.  It is the right way to build controls for vibratory equipment.  We feel so strongly about doing things the right way.  So, we are now just including it as standard feature.

To explain the Dynamic Break, we need to start with a quick review of the vibratory motors that make the equipment work.  A vibratory table, feeder or screener uses two rotary electric vibratory motors (or shaker motors) that counter-rotate.  Read More…


One Size Fits All – Part Deux!

David Strong

I enjoy movies and unfortunately for my wife, I’m not a particularly discerning movie viewer.  I can usually find some redeeming value in most movies, particularly if I get the DVD from the library, the dollar per laugh ratio is pretty hard to beat!  I have a bit of a soft spot in my heart for spoofs, even today I still get a kick out of movies such as “Hot Shots, Part Deux.”  More than once I’ve felt like the character Dexter, the guy they sent the men in to rescue and then sent the men in to rescue the men they sent in to rescue Dexter!  Sometimes I have to exclaim “you don’t understand.  I can’t walk…..they’ve tied my shoelaces together.”  Oh well, such is life.

In a previous Blog I talked about “One Size fits all….Not!” and how Cleveland Vibrator ‘tailors’ our line of fabricated equipment to meet the specific needs of our customers.  We certainly continued to do that last year.  Looking back at 2014, my engineering drawing log shows that we generated 3d models and associated drawings for twenty different flat deck vibratory tables, FA, configurations.  The smallest vibratory table was a FA-1818 RE 220-6(2) (18 inch square deck size) to the largest being a FA-6060 (60 inch square deck size).  In addition to the FA style units we also generated six different grid top vibratory tables, GT, which interface with a customer’s gravity or power roller section.  One of these Read More…


Using Vibration to Reduce Material Cost and Increase Profit Margins in the Plastics Industry

Katy Sabo

Industrial vibration can be found in multiple areas of plastics processing and can help reduce the costs of materials and increase profit margins substantially. With the use of equipment such as vibratory screeners, companies are able to reuse regrind and efficiently sort out the usable material from that of which needs to be discarded. There are other ways that industrial vibration factors into the processing of plastic products, read on to learn more.

What exactly is “Regrind?” Regrind is a term that seems self-explanatory and if you guessed that the it applies to mechanically reduced plastic components/products, you guessed right. Much of the plastic waste used in this process usually comes from a pre-consumer source, for instance processed scraps or even unused thermoplastic materials from injection molding. Read More…


Firestone & Cleveland Vibrator Team Up to Showcase at Pack Expo 2014

David Strong

Back in the spring of 1996 I was finishing up work on my engineering degree, had interviewed with The Cleveland Vibrator Company and had accepted their offer of employment.  My start date was in June, but first things first, I needed to finish up the degree and then get to work.  Sometime after accepting the job, Glen Roberts, my future boss, had gotten the idea that it might be beneficial for me and the company for me to spend the day in Chicago walking the Bulk and Powder Show.   This would give me a quick overview of the industry.   I think this was the second time I’d ever attended any type of trade show and the first for me when I knew I’d be involved with the industry targeted by the show.  Since then I’ve been fortunate to work a number of shows, Bulk and Powder, Foundry, World of Concrete, Interphex, NPE – Plastics showcase and the Pack Expo.  The Cleveland Vibrator has products in all these industries, both equipment and individual vibrators.  Again, that diversity of customers and applications is what helps keep it interesting and “entertaining” here at Cleveland Vibrator.

A couple of weeks ago I got a call from my local distributor for Firestone isolator products.  Read More…
