Ultrasonic Sieving Spotlight: What You Need to Know

By Jeff Hochadel

Are you experiencing any delays in your fine mesh screening processes? Do you find that your materials get clogged in the mesh of your screen deck? Finding a solution to roadblocks can be difficult. Ultrasonic Vibratory Sieving Systems can assist in making this process easier. Let’s dive deeper into them and learn more about what they can do for your production.

What is an Ultrasonic Sieving System?

A simple description of Ultrasonics is that they are high-frequency vibrations that go through screen mesh to relieve surface tension. By applying Ultrasonics, you can improve the throughput of materials up to 10x. You may also experience a boost in productivity when used with your vibratory sieve.

Here’s the Nitty Gritty on Remeshing Your Old, Worn Out Fine Mesh Screen

By Jeff Hochadel

As a manufacturer of vibratory and ultrasonic screening systems, screen wear is a huge issue for any fine mesh equipment. One frequently asked question we get from customers is, “How often should I replace my screen or mesh frame?” That can be a complicated question to answer since there are many variables to consider, including:

  1. What type of material are you screening?
  2. How often and how long do you run your screening equipment?
  3. What mesh are you using? i.e., How fine is the mesh or micron size?
  4. Are you running your screener with ultrasonics?

What Is On Size Sieving?

By Jeff Hochadel

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.

Small Batch Screening is Still a Big Deal

By Jeff Hochadel

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…

How to Properly Clean Fine Mesh Screens Without Damaging Your Equipment

By Jeff Hochadel

Over the years, I have read many articles about how to reduce fine mesh screen blinding on vibratory screeners. These solutions range from polyurethane balls to brushes. One of our most frequently asked questions is how to clean screens once they are blinded for fine mesh applications. Some customers simply throw out the blinded screens or send them back to our rescreening department for a new screen to be applied.

How to Reclaim up to 30% More of Your Ceramics Media

By Jeff Hochadel

During the process of manufacturing paints or other coatings, one of the steps involved is milling or grinding all of the dry ingredients into the liquid portion of the paint. These dry or solids consist of Titanium Dioxide (TIO2) pigments, binders, and various other powders. The liquid portion is mainly solvent or in the case of latex base – water. Once all of these dry ingredients have been thoroughly mixed (the proper term is dispersed) into the liquid base of the paint, the next step involves a high shear, high energy process called media milling.

In a nutshell, the paint is run through a chamber that has an enclosed horizontal shaft with discs or blades. The chamber is also filled with very small, spherical, grinding media. The media is made of different materials such as glass, steel, and ceramic media. Read More…

The Nitty Gritty of 3D Printing & Powder Sieving

By Jeff Hochadel

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…

Saving Green While You Screen

By Jeff Hochadel

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…

The 8 Steps of Ceramics Processing and Industrial Vibration

By Katy Sabo

“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:
