What Is Fabricated Equipment Design Flexibility?

By CVC Team

Typically flexibility is a good thing, both in business and athletics as well as life in general.  For Cleveland Vibrator, flexibility often means having a number of choices available to solve a bulk material problem.  Our line of pneumatic vibrators ranges from the small VM-25 piston vibrator to the huge 1900 single impact unit and about everything in between to include ball vibrators, turbine vibrators, air cushion piston vibrators with friction reducing coatings for long life, to a complete line of pneumatic foundry vibrators.  If the best solution involves electric vibrators, Cleveland Vibrator has wide range of rotary electric vibrators available with operating frequencies between 900 and 3600 rpms with force outputs from 30 to over 40,000 lbf!  That’s some flexibility for sure.

Along with our other vibratory equipment, vibratory feeders are great problem solvers. Feeders are well-known for their ability to move material from point A to point B effectively. However, a well-designed vibratory feeder offers flexibility to the end-user and increased safety and efficiency in the process.

Feeders can range from small base mounted CF-A, pneumatic powered feeders moving small quantities of dry bulk material in a controlled manner to a much larger base, as well as a cable-supported EMF, electromechanical feeder conveying literally tons of material an hour. This breadth of design capabilities allows our vibratory feeders to move material effectively in various industries for many different applications.

For example, we have incorporated vibratory feeders into the processes of these materials and more:

  • Almonds
  • Crushed Limestone
  • Shelled Corn
  • Powdered Metal
  • Metal Billets
  • Various Pipe Fittings
  • Scrap Brass and Bronze
  • Crushed and Shredded Automobiles
  • Hot Dross

We work with a variety of industries feeding an endless variety of materials!

Installing Vibratory Aids on Equipment: What Are My Options?

Installing Vibratory Aids on Equipment: What Are My Options?

By CVC Team

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 appropriate size pneumatic piston vibrator on the side 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 broader 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.

Often with equipment one of the first things that comes up in initial discussions is the design height or discharge height of the unit.  With vibratory feeders (EMF) and screeners (EMS) there’s always a concern about 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…

Unique Design Options Available for Specific Vibratory Compaction Table Applications

By CVC Team

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 the final setup 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 are 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 is almost an infinite number of options and variables available to accomplish the customer’s goal, regardless of how simple or Read More…

Vibratory Feeders & Screeners: The Affects of Force, Acceleration and Frequency

By Jack Steinbuch

We often receive calls from customers that need to make adjustments to the product flow in their vibratory feeders or screener/feeders.  Our challenge is to determine what style equipment is being operated to provide the appropriate options.  The following are three basic drive options which produce linear force that can be used to power vibratory feeders or screener/feeders.  To clarify, a screener/feeder is designed to feed the material with that same vibratory action also serving to help stratify the material – Read More…

Vibrators Don’t Damage Equipment, Wrong Installations Do

Vibrators Don’t Damage Equipment, Wrong Installations Do

By Craig Macklin

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:

Are You Afraid to Ask About Sizing Industrial Vibrators for Bins or Hoppers?

Are You Afraid to Ask About Sizing Industrial Vibrators for Bins or Hoppers?

By Jack Steinbuch

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.

Stroke, Frequency and Force: The Keys to Vibratory Compaction

Stroke, Frequency and Force: The Keys to Vibratory Compaction

By CVC Team
Compaction, Vibratory Compaction, Vibrating Table, Vibratory Table, Compaction Table,

One of the more common applications for industrial vibration is settling or compacting a wide variety of products with a vibratory table. Compaction applications range from foundry sand around a core to powdered metal, beer bottle caps, individual sugar packets, ceramic mixes, to concrete blends used in ATM wall enclosures. 

There are many vibratory equipment options available that will effectively settle and compact your material, including:

Regardless of the equipment, we start by understanding the material and working with a few basic parameters

The most critical parameters in any compaction project are vibration frequency, and the amount of force applied. These two parameters drive the third parameter, stroke or displacement. Heavier materials respond best to high-frequency vibration and the resulting smaller stroke that high-frequency vibrators produce. Lighter material or discrete parts often compact best with a lower frequency vibration and a larger stroke. Typically, we start testing a product at a given frequency based on bulk density and adjust the force to load (g’s) ratio to get the best compaction results. With the wide range of vibrators at our disposal, we can choose from air-cushioned pneumatic vibrators (VMSAC), rotary electric (RE) vibrators, or electromagnetic (CM) vibrators that best suit the frequency and force requirements.

Powder Metal Fine Mesh Screening Customizations

By Jeff Hochadel

As a custom equipment manufacturer, we have quite a bit of flexibility in what we can offer.  Sometimes a screening application calls for requirements that a standard vibratory screener just cannot accommodate.

Recently, a customer asked us to redesign his powder metal screening operation in order to provide additional headroom for an additional piece of equipment. His application requirements were a vacuum, two-deck screening, and ultrasonics on both screen decks PLUS he wanted to increase production. He currently was also Read More…

Designing Vibratory Equipment to Meet Size Contraints

By CVC Team

My wife will be the first person to tell you that she hates shopping.  At almost six feet tall, it can be a challenge for her to find something that fits right with an arm length that isn’t some place closer to the elbow when it should be at the wrist.  Therefore, it always kills me when she comes home with something that is touted to be “one size fits all” my standard response is “one size fits none!”    Over the years, I’ve found that this theory applies to material handling equipment as well.  On most applications, each customer’s requirements are just a bit different from the previous set of design parameters.

When I first started working at The Cleveland Vibrator Company, Read More…
