Air Powered Vibratory Feeders: 3 Things To Know Before Making a Buying Decision

By Mike Stratis

When it comes to handling dry or semi-dry bulk material, there are few means to transport the material from point A to point B. The common options are pneumatic conveying equipment, frequently dense or dilute phase, belt conveyors, screw augers or vibratory feeders, flat pan style, or enclosed tube style. There certainly is a time and place for each of these options but we will focus on the vibratory feeder design.

Companies looking to make a buying decision on which type of equipment to install that will handle the material typically turn to the vibratory feeders that are powered by a pneumatic or air piston vibrator for one of, or a combination of, these reasons:

Air Powered Feeders Work Well Within a Budget – First, and maybe most importantly, the purchase price. The air-powered vibratory feeders can be the low-cost alternative to the electromechanical or electromagnetic powered vibratory feeders. The biggest cost savings can come directly from the vibratory drive or mechanism and the vibratory controls. Electromechanical feeders typically have two vibratory motors while the electromagnetic feeders typically have one large vibratory drive attached. Each of these electric-powered options requires an electrical control box, with dual Pneumatic Vibrator, Industrial Vibration, Cleveland Vibrator Companythermal overload protection for the electromechanical vibratory motors for on/off operation, speed control, or intensity of the vibration control. In contrast, the air-powered feeders are driven by a single non-impacting piston. For example, the Cleveland Vibrator VMSAC units are either controlled by a manual ball valve or 2-way, normally closed, solenoid valve.

Let’s Clear the Air on Vibratory Drives for Hazardous Locations

By Jack Steinbuch

Over the years I’ve received a number of requests for industrial vibrators or vibratory equipment that need to operate in a hazardous location.  Most requests include the classifications they are either given or think they need, but often aren’t familiar enough with them to know what their application may really require.  I believe, for vibrating motors especially, that most confusion stems from recognizing the difference between dust-tight and explosion-proof construction.

Our challenge for these applications is to clarify the classification being requested and offer possible alternatives to meet them.  First, to my understanding, pneumatic powered drives are acceptable for any hazardous location. You only need to be concerned if you use an electrically activated valve to start/stop it, to make sure it meets the classification of the hazardous area.

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

By Mike Stratis

Are you looking to add a vibratory compaction table to your facility’s manufacturing and shipping processes? 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, each of which can impact the equipment’s overall cost.

For starters, what can a vibratory compaction table 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 the 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 before 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 cast 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

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…

2015: The Year of the Vibratory Table

By 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

By 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 as 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 5 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 1960s 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

By 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…
