Why Is My Bulk Material Feeding or Screening Inefficiently?

By CVC Team

Dec 21

Once again I’m touching on the topic of the proper setup of rotary electric vibrators (RE) when they’re used on vibratory equipment. Most of the vibratory equipment manufactured by The Cleveland Vibrator Company uses two rotary electric vibrators to produce linear vibration. Vibratory tables (FA), vibratory grid tables (GT), electromechanical screeners (EMS) and electromechanical feeders (EMF) are all designed for the vibrators to counter rotate. Again, counter rotation simply means that the vibrators rotate in different directions, one clockwise and the other counter clockwise. It doesn’t matter which vibrator of the pair rotates clockwise or counter clockwise, it’s just important that they both don’t rotate in the same direction.

I recently tagged along with Jack Steinbuch on a visit to a customer who was experiencing some problems with a vibratory hopper feeder (RFM). After inspecting the unit we asked the customer to remove the weight covers on the vibrators so we could check the rotation direction. Once the weight covers are removed from the same end of each vibrator it’s very easy to see the direction of rotation as the vibrators are started up. At startup it was clear that the vibrators were NOT counter rotating as required. Read More…

It’s Complicated, or Is It? The Frequency, Stroke & Acceleration Relationship

By Jack Steinbuch

Nov 30

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…

The Nitty Gritty of 3D Printing & Powder Sieving

By Jeff Hochadel

Jul 06

Here at HK Technologies, we have been sieving powder metal for quite some time. Our Ultrasonic Sieving Systems allow for sieving very fine atomized powders – down to 20 micron on conventional wire mesh and in some cases finer –using electroformed material provided by PrecisionForm, Inc. As the 3D printing industry has exploded, so has the need for finer powders. While I am no expert in the field of 3D printing, I have been involved in several areas requiring finer and finer mesh sieving.

Many of the 3D printing manufacturers install a very simple inline vibratory screener system in the powder feed system. These simple screeners typically sieve the powder through a 74 micron or 200 mesh screen. This ensures that no large foreign objects are being fed into the powder part building process. Many times the end-user needs finer powder to create the intricate parts they are producing. This powder is typically said to be +20 -25 micron powder. We are also told this powder is classified through an air classification process. The process, while quick and relatively easy, leaves a powder that is not always what it is claimed to be. When asked to check the accuracy of the particle size, we find there is almost always a significant amount, 10% or more, of finer material than claimed. Read More…

Why Recycle Glass? The Answer Is Clear

By Katy Sabo

Apr 20

Remember the days of “Tube TVs” and “Low Radiation” computer screens?

I remember walking into Cleveland Vibrator and seeing, what I would describe as, the land of misfit computer screens that had been stored away through the many years that Cleveland Vibrator has been in business. One day they disappeared and the land of misfits was replaced by trade show accessories. Working here has opened my eyes to the many industries that don’t get the attention they well deserve, especially recycling. Recently, I was invited to visit a customer whose specialty was Glass Recycling of old TV screens and computer monitors. Ding, ding, ding, the lightbulb went off… this is where those “misfits” disappeared to. This got me thinking, what exactly can recycled glass be used for?

The glass used for these old monitors and displays is referred to as CRT, Cathode Ray Tube Glass, and it is estimated that the typical CRT device is made up of between 15 to 90 pounds of glass (depending on device) that protects the users from the radiation produced by the electron gun and beam gun inside that device. Since the emerging high demand of LCD, LED and Plasma Screens of the 2000s, it is an estimated 57 million computers and televisions are sold annually in the U.S. according to U.S. Environmental Protection Agency. Households are now discarding old models of outdated technology at a much higher rate than we have ever seen before. Read More…

The 8 Steps of Ceramics Processing and Industrial Vibration

By Katy Sabo

Apr 06

“To acquire knowledge, one must study; but to acquire wisdom, one must observe.” – Marilyn vos Savant

You know those ceramic dishes your mom uses to serve Sunday dinner? What if I told you that Industrial Vibration played a part in making those dishes possible?

The Ceramics Industry covers a wide range of products from traditional ceramics, such as pottery and chinaware, to technical ceramics for chemical, mechanical or thermal applications. I will provide you with a brief overview of the manufacturing process of traditional ceramics. I will help you see where Industrial Vibration fits into the processes as well, so brace yourself; here we go!

What exactly is Ceramics?

Ceramics can be defined as a class of inorganic, nonmetallic solids that are subjected to high temperatures for manufacturing use. I spoke about the term “traditional ceramics” which will be the focus of this post. These are ceramic products that are produced from unrefined clay, and combinations of refined clay and powdered or granulated non-plastic minerals. This includes pottery, stoneware, chinaware, porcelain, etc. To create these end products, the ceramic matter needs to go through the traditional manufacturing process, which goes as follows:

How To Improve Ceramic Slurry Screening With Ultrasonics Deblinding System

By Jeff Hochadel

Mar 31

Liquid ceramic glaze or clay slurry materials are used in a variety of products and applications ranging from decorative and protective glazes to tile glaze or electrical porcelains. Typically this material starts with either Koalin clays or ceramic powders mixed with water or other liquids to form a slurry. Depending on the application this slurry will need to be screened to remove any agglomerates (powders that did not get dispersed during the mixing process). This is a very important step because, in many applications, this slurry or slip will eventually be applied to an exterior surface either as a decorative or possibly a protective coating. In either case, the coating needs to be free of any oversize agglomerates or debris allowing for an attractive smooth finish free of any pits or blemishes. The finer the screen or sieve used, the better or smoother the finish.

Depending on the application, screening can range from simply pouring the slip or slurry through a filter bag with a relatively coarse mesh to using vibratory screeners with finer mesh sizes – down to 120 mesh or maybe finer. This is where the difficulties begin. Read More…

Brake. Don’t Break.

By Craig Macklin

Feb 02

To the casual observer, Vibratory Equipment might look like pretty simple stuff. You just slap some vibrators on the thing to make it shake, right? Anyone can make that! Well, as we’ve seen in some other detailed posts from Jack Steinbuch, there is more than meets the eye to designing and building something that will work and last.

One design feature that we have offered and recommended in the past is the Dynamic Brake. I say that we offered in the past because we are now moving to just make Dynamic Brakes standard features. We recognize that many folks may not know what a Dynamic Brake really does in order to see it as a good option to add. However, as you will see in the explanation and video here, it is more than a good option. It is the right way to build controls for vibratory equipment. We feel so strongly about doing things the right way. So, we are now just including it as standard feature.

To explain the Dynamic Break, we need to start with a quick review of the vibratory motors that make the equipment work. A vibratory table, feeder or screener uses two rotary electric vibratory motors (or shaker motors) that counter-rotate. Read More…

Perforated Plate

This is also a fairly common and widely used screening media for many applications including scalping, sizing and dewatering. Perforated plate, as relates to sections installed in vibratory screeners, is typically designated by the openings, the bar width (amount of material between the openings), centers (distance between the holes as well as staggered or straight line) and thickness.
