How Hoppers Can Improve Performance of Feeders & Screeners

By Jack Steinbuch

Hoppers can aid in the performance of material handling equipment, plus provide health and safety benefits for your workforce. To begin, we will review the advantages hoppers can provide to improve the performance of feeders and screeners for bulk loading applications.

Okay, so what is a hopper?

Hoppers can be stationary with steeply sloping walls to allow free-flowing material to discharge onto the feed tray. Due to their steep walls, these hoppers can have a high dump height, depending on the volume. For lower dump heights and/or poor flowing materials, a vibrating hopper is a great solution. The hopper is attached to the vibrating body and the vibrators are then upsized to compensate for the increase in vibrating weight. The material is fed from the hopper onto the equipment.

Reduce the Noise Level on Your Vibratory Equipment

Reduce the Noise Level on Your Vibratory Equipment

By Jack Steinbuch

OSHA specifies that a hearing conservation program should be in place when “noise exposure is at or above 85 decibels averaged over 8 working hours, or an 8-hour time-weighted average (TWA)”. This can be an issue for some vibratory equipment. However, we have selections available that will reduce noise levels which can result in many positives for your facility (OSHA).

For example, did you know investing in noise-reducing vibration can lead to an increase in productivity and overall safety? High noise levels can lead to short- and long-term physical damage including ringing ears, temporary changes in hearing, and long-term hearing damage or loss. But, less commonly known, it can also put a strain on your pocket by reducing productivity, contributing to poor communication and concentration, and can even contribute to workplace accidents by limiting your employee’s ability to understand speech (OSHA).

Since there is a wide variety of vibratory equipment, for this blog, we will focus on “brute force” vibratory equipment.  The vibrating body is directly installed on the equipment and is driven by a vibrator or dual motors, and the supporting structure is isolated from the vibrating body. Now let us look at potential ways to reduce their noise level:

Automate the Hammer Swing by Following These 5 Steps

By Cleveland Vibrator Team

Our team is frequently asked about the proper installation of our Single Impact Air Knocker units. Since these units require two strokes of air for proper operation, the required components and installation process are slightly different than a more traditional pneumatic piston vibrator. Here, we will answer frequently asked questions and walk through the step-by-step installation process.

Step One

After properly sizing and selecting the units (which can easily be completed by utilizing our Vibrator Selection Guide!), it is time to install. First order of business, what are the components required for proper operation? There are a few items needed:

  1. The Single Impact Air Knocker (Complete with the Exhaust Port Protector and Grade 5 mounting hardware, provided with each unit)
  2. The Mounting Channel
  3. Hoses
  4. Valve
  5. Filter/Regulator/Lubricator
  6. Safety Cable
  7. Timer Box (Optional)

What You Need to Know About Clogged Industrial Pipe Issues and Vibration

By Cleveland Vibrator Team

Material flow issues are the worst. Not only are they a headache to deal with during production for the team out on the floor, but they may be costing you valuable time and money in the long run. The usual suspects for material flow hang-ups typically occur in bulk supply hoppers or industrial bins. But, what about those industrial pipes and chutes transferring materials throughout various stages of production?

Industrial vibration is not just for those usual suspects; it can be just as successful when applied to those transfer chutes and pipes! Not only does it get the job done, but it is economical and ultimately saves the integrity of your equipment and your team’s shoulders and backs.

How to Adhere to Social Distancing Protocols & Promote Safety During a Pandemic Using Vibration 

By Cleveland Vibrator Team

In this pandemic, manufacturers have been called on to help make items critical to stopping the spread of, or help with the treatment of, the virus.  Namely, our nation needs an increased focus on the manufacturing of PPE, cleaning products, and ventilators.  Well, we at Cleveland Vibrator Company are a manufacturer. However, we don’t have the capability to make masks, sanitizers, or ventilators.  We are proud to be deemed essential and contributing to keeping the production and transportation of key goods intact.  But we want to be doing more to directly contribute to stopping the spread.  So, we were inspired to think of products and projects that have helped customers reduce the density of workers in a small area and could now apply to enable safe distancing on processing and production floors.  Here is a couple: 

Application #1: Bulk Food Packaging

Production conveyor line without the use of vibratory equipment – Cleveland Vibrator Company

In packaging bulk foods such as frozen onion rings, bagels, or meat patties, typically there is a step between the box filling station and the close and seal station to settle the product.  When the box gets filled with products, especially odd-sized items, the product tends to cone so that amount of product that by weight is supposed to fill the box, is in a mound that exceeds the height of the box.  Often, this settling is handled manually by workers standing shoulder to shoulder at the conveyor between the filling and close and seal to shake the boxes and get the products evenly settled.      Read More…

What Is On Size Sieving?

By Cleveland Vibrator Team

Many times, a customer’s problem with product throughput can be solved with some simple solutions. I am not going to discuss screener ball decks, screen rings, or ultrasonic sieving but rather some simple solutions for those applications where the powder wants to sieve but is just not going through the screen! First, let’s discuss on size sieving.

What is On Size Sieving?

On Size Sieving is a problem that occurs when the actual particle that should pass through your sieve or screen is just a hair too big or too small for the screen you’re using.

For example, the lab indicates that your sieve analysis shows 70% of your powder is passing through a 53-micron sieve (270 mesh), but you can only achieve 45% passing through the 270 mesh in production.

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.

Small Batch Screening is Still a Big Deal

Small Batch Screening is Still a Big Deal

By Cleveland Vibrator Team

The typical customer who calls or emails with a process question has either hundreds of pounds per hour or tons of material per hour to screen. Although these may be the majority of the applications, I do get many inquiries where the customer only has to process maybe 20 or 30lbs/hr. (or less) but still needs a vibratory screener. These small-batch screening applications are sometimes a little more challenging to solve than the typical large-batch application. Some applications may require a much finer mesh, there’s not much room to work with, or the material is extremely valuable. Besides our standard screeners, we also have the capability to manufacture a special screener around the customer’s process. I don’t know how many times I have seen an overly large vibratory screener handling an application where a screener half the size would suffice.

So, we first need to determine how much material the customer plans on running through the screener per hour or per shift, then we need to determine the mesh size requirements.  We need to answer two questions: Read More…

Shaking It Out & Saving the Earth One K-Cup at a Time

By Cleveland Vibrator Team

Being a mom, there are certain things in life I cannot live without. Obviously, Disney Junior and endless amount of toys make my life a lot easier but coffee gives me life. It sounds dramatic, I know, but any parent out there reading this knows exactly where I am coming from! We all have our vices and coffee is my kryptonite. I don’t discriminate when it comes to preparing java, whether it is from my favorite local roaster, my own coffee pot or that quick instant cup out of a Keurig, you can bet your bottom dollar not a drop will be left in my mug at day’s end.

Single-serve coffee cups have given a new meaning to coffee on-the-go. Even though the cost of the single-serve cup is proven to be higher overall than the standard coffee grounds, the savings in time makes it worth it for the die-hard caffeine addicts. Guilty as charged and with no shame at all, I am one of those addicts but the tree hugger side of me sticks to the old school Mr. Coffee maker every morning. My Keurig is on standby if I desperately need that afternoon pick-me-up and takes residence behind me in my office as I write this blog. I like sharing so it is “open to the public” during work hours for my fellow CVC comrades, but they provide their own goods! Coworkers know to discard their used K-cups into my recycling box but it made me wonder, how many other people think to recycle them? Read More…

If Archie Bunker Designed Vibratory Equipment…

By CVC Team

When I joined the Cleveland Vibrator family, I had just graduated with a Bachelor’s degree in Mechanical Engineering and had no prior experience in the field of industrial vibration or vibrators. During the course of my formal education, I had one class that dealt with vibration, the focus of the class as I recall was how to eliminate it, certainly not how to use it to perform meaningful work. When I was hired on, my informal education into the world of industrial vibrators and vibration began. Just like coming into any family, you learn the way the family works, the teams they root for, the legends they admire and the folks to be avoided.  I feel fortunate that I had some excellent family members to bring me up in the world of vibration.

When it comes to vibratory equipment there are many ways to introduce vibration into a structure and produce the desired results. You may be looking to use vibration to move bulk material from point A to point B, screen large particles from small or compact more material into a box.  Read More…
