The Nitty Gritty of 3D Printing & Powder Sieving

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…

3 Ways To Measure The Strike Force Of A Pneumatic Vibrator

3 Ways To Measure The Strike Force Of A Pneumatic Vibrator

By CVC Team

Recently the sales team forwarded the following question from a customer –

“We use some of your impulse piston vibrators to fill molds with powder. Do you have a recommendation for a way to measure the strike force such as a G-force meter or Accelerometer? Any ideas you have would be greatly appreciated.”

This seems like a pretty straight forward question but upon closer inspection, it gets a bit more complex. So let’s break it down and look at the pieces of the question. It’s always important to make sure we’re on the same page in our understanding of the question and terminology used. Read More…

Unique Vibrator Installations & 5 Ways To Repair Damaged Walls

Unique Vibrator Installations & 5 Ways To Repair Damaged Walls

By CVC Team

Jun 15

Since 1923, we have been a part of many vibrator installations on hoppers and bins. One of our major markets is supplying industrial vibrators to the feed and grain industry. I have spent time talking to and visiting folks who ensure their facility operates efficiently with minimal downtime. During those visits, I’ve come across many unique techniques to mount a vibrator on a bin or hopper—specifically, the installation and types of channels and mounting brackets.

Where should you install your industrial vibrator?

Even if the installation doesn’t fit the standard mounting practices, our installation manuals are still helpful. In most cases, we suggest mounting the vibrators on the sloped section of the hopper or bin about one-third of the way up from the discharge. If using two vibrators, we recommend spacing them 180 degrees apart. If using three, we recommend 120 degrees apart. Staggering the vibrators will maximize the effect on the bin walls to assist in material flow.

Saving Green While You Screen

We know it’s a big deal when it comes to talking about “sticker price”, especially when it deals with expensive pieces of equipment, or rather process investments that will provide efficiency and give you the best final product possible. Customized pieces of equipment tend to fall under the larger price tags, but don’t be fooled, there are ways to provide the best equipment possible while keeping it in a reasonable price range. Cleveland Vibrator and HK Technologies take every unique application and gives you a solution to best fit your process, and sometimes that solution much simpler than what you thought it was going to be…

Although we have a complete line of screening equipment from small lab models in 3”, 8” and 12” diameters all the way up to 60” diameter screeners we still receive numerous calls from customers looking for customized screeners built around a piece of equipment or a specific process. While many of these applications can be challenging and downright difficult, our shop manager finds them all interesting and challenging. One of the more popular requests is what we call drum sifters or drum screeners. The screeners are simple screeners designed to fit on top of an existing container or a manway on a piece of process equipment. Typically, the customer is not looking to spend a lot of money and is just interested in a way to remove Read More…

Temperatures Are Rising…So Are Moisture Content Percentages

Temperatures Are Rising…So Are Moisture Content Percentages

By Mike Stratis

Jun 01

Now that we are past Memorial Day weekend, and thank you to all that have served, are serving or will serve our country, the summer months are upon us. For some, and depending where you live, these are the best parts of the year, namely, because of the warmer temperatures. While we enjoy the extra hours of sunlight and are exposed to more vitamin D, Mother Nature can have a serious effect on manmade structures. This is certainly the case for Texas and Oklahoma right now as many cities in this part of the country have experienced record rain falls for the month of May. This amount of rain can often be attributed to the rise in moisture content within the atmosphere.

So, why is this important for industrial vibration? Good question. Read More…

What You Need To Know About Screening Media – Part IV

By Jack Steinbuch

May 07

This blog is the fourth in a series that has been dedicated to typical screening media that are installed in Vibratory Screeners with their advantages and disadvantages so you can be in a better position to assist us in the selection process.

Profile (Wire) Deck

This screening media is used primarily for dewatering applications. Additionally this decking is used in the Coal industry for drain & rinse and desliming applications. This decking is also utilized in screeners for the iron ore, potash and phosphate industries.

Profile decking is most often stainless steel construction, but can also be constructed from other metals. This decking most typically consists of V-shape or triangular wire profiles that are supported in parallel on cross bars. 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 CVC Team

“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…
