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.

As my incredibly knowledgeable associate Mike Stratis just provided a posting about accessories to consider for your installation of a pneumatic vibrator, I thought I would provide a follow-up piece to discuss what to expect AFTER the install. As with any equipment, pneumatic vibrators and their supporting accessories do require some love, attention, lubrication and cleaning from time to time. Here is what to expect if you want to get the longest and most consistent life out of your pneumatic vibrator, whether a piston, turbine or ball.

Air Piston Vibrators 

Cleveland Vibrator Pneumatic Piston Vibrator Group ShotLubrication – First and foremost, check your lubricator with some frequency.  If you operate continuously, you might check and/or refill every 1-3 weeks.  If your use is intermittent or infrequent, you might schedule on a 1-4 months.  The use of internal coating in the vibrator can reduce or remove the need for lubrication.  But, coatings without the use of lubrication will typically wear out faster than a coated or uncoated piston vibrator that is properly lubricated.  Depending on size and duty cycle of your vibrator, you might use a pint of lubricant (we recommend our MXR-12 VibraLube, which is 10W-NR) every 2 weeks to 2 years.

When it comes time to review solutions to the material flow problems inside the hopper, pipe or chute, there are a few things to keep in mind when putting together a budget for the project. Besides the vibratory flow aid itself, there are additional components required before installing the unit. We will discuss these items and estimated costs to acquiring these components. Here is the short list:

  1. Industrial Vibrator – pneumatic piston vibrator, single impact air knocker, pneumatic turbine vibrator, pneumatic ball vibrator
  2. Safety cable
  3. Mounting channel or plate
  4. Hose to connect vibrator to on/off valve
  5. On/off valve
  6. Hose to connect on/off valve to air prep component (filter/regulator or filter/regulator/lubricator)
  7. Lubricant (if necessary)

Depending on the size of the hopper or piece of equipment that the pneumatic vibrator is going to be installed on, the price of the vibrator itself can range from about $100 to as much as $10,000. But, within that range, vast majority of the units are going to be between $100-$1000. Read More…

Vibrator Coating Testing Results: Only Time Will Tell

Some time back in the mid-60s Cleveland Vibrator started working with coating technology in an effort to improve the performance and longevity of our line of pneumatic piston vibrators.  For best operation while consuming a minimum of compressed air, the piston and the body of any pneumatic piston vibrator need to be very closely matched.  Clearance between the moving piston and the fixed body is very fine, in certain installation orientations the piston rides on the body of the vibrator creating a metal on metal contact area.  Because of the metal on metal contact it is recommended to supply a pneumatic piston vibrator with lubricated air.  The appropriate amount of oil mist in the air stream will lubricate the moving parts, reducing the co-efficient of friction between the surfaces and extend the life of the vibrator.

Cleveland Vibrator’s investigation into and early use of friction reducing coatings was designed to leverage the benefits of the coating to enhance the performance and extend the life of the vibrator by reducing parts wear due to friction.  If not properly maintained and lubricated a piston vibrator will start to wear due to the piston/body surface contact.  Indicators of excessive wear will be reduced performance, less force output and more air consumed at the same operating pressure.  As the piston and body wear over time the gap between the two parts will increase, with the larger spacing air can “blow by” the piston, blow by air isn’t effectively used by the vibrator to generate force it simply exhausts out of the body.  Read More…

When it comes to unloading dry or semi-dry bulk materials from a hopper trailer, belly dump, side dump, end dump or similar type of truck, there are a few vibratory options available to the market. Depending on the power supply available on the mobile equipment, air or electric, the vibratory components change. We will first look at the air powered vibrator options then turn to the electric powered vibrator options.

The pneumatic or air powered units that are available are the piston style vibrator or the turbine style vibrator. These two are by far the most common air powered vibrators found on mobile equipment. The Cleveland Vibrator Vibra-Might air piston vibrators are popular units in the field. These vibrators have a dual diameter piston which allows for start up at any mounting angle and there is no spring on the inside of the vibrator. No spring equals less wear parts. These vibrators also have a single exhaust port and come standard with the exhaust port protector. The exhaust port protector helps keeps dust, dirt, water and other contaminants out of the bore of the vibrator. These Vibra-Might air piston vibrators come in both 4-bolt square base and 2-bolt rectangular base designs. Read More…

Cleveland Vibrator recently added a new employee in the Fabricated Equipment area of the company.  At the end of 2015 our CEO declared that 2016 would be a “year of investment” here in terms of both people and equipment.  It’s exciting to see this sort of thing happening, good people coming on board as well as some new CNC equipment on the immediate horizon.  It all makes Cleveland Vibrator a better company.  While getting to know a bit about our new guy in the Fab area, we talked some about his work experience and the opportunity at Cleveland Vibrator.  One of the things he already likes about the position is that he gets to see a piece of equipment completely manufactured, start to finish.  I told him that’s one of the things that I’ve always enjoyed about my job, getting to be involved with the complete process often starting with the solution concept generation phase to final testing of that solution prior to it shipping out to the customer.

I think most engineers are problem solvers and that’s one of the aspects of this profession that they find interesting and rewarding.  That’s certainly the case for me.  I’ve always found the diversity of Cleveland Vibrator’s customers and their problems very interesting.  Plus, I feel that we have a very “intimate” manufacturing process, it’s all here in one location.   Whether it’s the manufacture of a pneumatic piston vibrator, as an example the 1300 VMSAC, air cushion vibrator piston vibrator or a large vibratory feeder Read More…

When turning to a pneumatic piston or air piston vibrator for bin clean out or bulk material flow out of your material storage vessel with a conical transition hopper, there are a few things we review to help determine the best unit for the job. Here are the various sets of criteria we review before making a recommendation:

  1. Find number of vibrators needed
  2. Find strength of vibrator needed
  3. Find best air piston vibrator for application

Step One: Find the Number of Vibrators Needed

To find the number of vibrators recommended for the conical hopper, we look at the geometry of the vessel being vibrated. The geometry, size and shape, of the vessel tells us the number of vibrators needed for the most effective vibration transfer into the material. There is about 5 feet of effective radius for the vibration energy from where the vibrator is mounted. Here is a visual aid which allows you to see how many vibrators are needed based on the size of your hopper. Read More…

Generally speaking, in life, choices are a good thing.  This applies to industrial vibrators and vibrating equipment as much as it does for lunch time options.  In terms of fabricated vibratory equipment, Cleveland Vibrator offers a variety of solutions to processing and material handling problems.  Regardless if the need is for a vibratory feeder, screener, compaction table or vibratory belt table, our sales and application folks are up to the challenge of solving the particular needs and requirements of our diverse customer base.  As I mentioned in earlier blogs, when it comes to vibratory equipment, one size in fact doesn’t fit all.  Rarely do one customer’s particular requirements match up exactly with another customer’s, the solution may be similar in type but not in exact physical size.  Tailoring to meet the individual needs of each customer is part of the Cleveland Vibrator fabricated equipment DNA.

One of the many types of fabricated equipment manufactured by The Cleveland Vibrator Company is the volumetric feeder.   Internally, they are generally referred to as Hopper Feeders, RFM, these units can be pneumatic or electric powered.  The key design element is that a vibratory feeder has a storage hopper associated with it which accepts and stores dumps of material and then feeds the material out of the hopper in a controlled manner.  Read More…

All organizations that have stayed in business for many years have “go-to folks” they depend on when difficult situations or tough problems arise that need to be taken care of. For example, how many times have we watched a football game and experienced the quarterback take his team 90 yards in under two minutes to win a game or the linebacker or safety make that key tackle or interception for a last minute victory? If you root for every team but the Browns, we’re sure you’ve experienced this enough to know the importance the role these key players fulfill. These are go to folks and it is no different in the business world, especially here at The Cleveland Vibrator Co.

I think we are blessed with several go to folks on our team. When a customer calls Cleveland Vibrator, they are not just talking to a sales associate but to engineering, manufacturing, purchasing, marketing, shipping and yes, even our owners from time to time. I believe this collectively makes Cleveland Vibrator a “go to company” for many special applications. I call this our “NICHE” business and feel it has been one of Cleveland Vibrator’s strengths, even before I was given the opportunity to join the team in 1968.
