Stroke, Frequency and Force: The Keys to Vibratory Compaction

By CVC Team

Sep 05

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

Aug 20

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…

Grain Entrapment and Engulfment

By Craig Macklin

Jul 26

Due in a large part to the efforts of NPR, I recently became more aware and educated on a tragic and horrifying issue in the Feed and Grain industry: Grain Entrapment and Engulfment. Basically, this is the incidence of being buried and/or drowned in bulk grain. I shudder to even think about the experience.

Reading through NPR’s listing of incidents, I noticed a couple of things that had me thinking more about why this is happening and whether Cleveland Vibrator Company might play a part in future prevention. First, the incidents reported seem to be more frequent in the past few years. Second, there is some recurrence of incidents stemming from people climbing into bins, hoppers and silos that have stuck material in order to “unstick” it.

Certainly, the second item connected with me as we are a manufacturer of material flow aids, like industrial vibrators and knockers, that are used to prevent or correct material sticking, clogging, rat-holing and bridging. I wanted to learn more about what we could do. So, I called Read More…

Designing Vibratory Equipment to Meet Size Contraints

By CVC Team

Jul 22

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…

Low Cost, High-Frequency, Screen Deblinding – Turbomite Deblinding System

By Jeff Hochadel

Jul 01

Several weeks ago, I was reading an article in one of the technical journals discussing the variety of ways to eliminate screen blinding on vibratory equipment. The article discussed a number of “old school” solutions such as rubber balls, clean rings, spray nozzles and brushes. These methods have been around for decades and produce a low to moderate level of success in keeping the screen surface from blinding or clogging. The article also discussed the most effective solution for screen deblinding – Ultrasonics. While it is the most effective, ultrasonic deblinding systems are also the most expensive. If you are not familiar with ultrasonics Read More…

Value of Industrial Vibrators Part 2: Feeding Cows…and Me

By Craig Macklin

Jun 04

If you didn’t read Part 1: $100,000, you should immediately. It is life changing.

All set? Great. Welcome back. Incredible wasn’t it? If you didn’t really go read it, you might struggle with your conscience later, but you should still be able to follow the rest of this post fine.

Similar to the value of vibration in diamond mining catching my attention, the value of industrial vibration to feeding cows also caught my attention. Why?? Read More…

The Importance of Getting All the Data for Screening Applications

By Jack Steinbuch

May 28

We receive numerous requests for Screeners where the effective screening area has been specified by the customer. While a decent amount of these requests work out to the best of our knowledge (since not everyone is willing to admit that they may have erred in their request), we do offer to review the application to confirm that the screening area is adequate if sufficient data is provided.

Our challenge in this instance is to get the customer to provide us with the information we require to determine the optimum size, and Read More…

Slack Fill Packaging and Economics of Marketing vs. Material Cost

By Craig Macklin

May 24

Not too long ago, I was speaking with Jack regarding a letter he was writing regarding the extra space he found in the packages of Non-Dairy Creamer Powder he likes. His theory was that the powder product was settling after packaging and during transport, which was leaving more space in the package than was needed. He was writing to the manufacturer to suggest that they investigate a vibratory table to settle the product during packaging, which would allow them to make the packages much smaller (likely ~25%) and save significant dollars on the material for the packages. I stipulated that the extra packaging Read More…

Magical Powers of Piston Vibrator Design?

By CVC Team

May 21

The VMR model is one of those unique mergers of old and new technologies. The current concept was developed by combining our older MI units from the 1950s and 60s, the first generation Vibra-Might design from the 70s and 80s and our design features of the 90s. The VMR unit features a totally enclosed one-piece body design that operates without the dependency of a starter spring and will start in all mounting arrangements. This is coupled with our revolutionary Read More…

Improving Production Speed of Cast Concrete

By Jack Steinbuch

Apr 24

In designing and manufacturing custom vibratory equipment, I see customer inquiries for a myriad of potential applications to solve production challenges or improve production rates. Recently, a producer of decorative stones presented us with a challenge. The stones are produced from wet cast concrete mix molds. These molds need to be vibrated to de-aerate (remove air bubbles) and consolidate the concrete in the molds. This was being done manually on a vibrating table, typically one mold at a time. They wanted to automate their production to reduce their labor time. They had invested in production equipment that would quickly fill the molds, but had yet to come up with a method to take advantage of that automation by vibrating each mold at the same rate.

We concluded that our Read More…
