The Ultimate Powder Sieving Solution: High-Energy Screeners That Save Time & Money

By CVC Team

Advanced powder screening technology needs are increasing for high-energy sieving screeners, calling for smaller particle sizes with stricter specification requirements. Industries that work with dense materials, such as 3D printing or additive manufacturing, need precise control over particle size for production. This contributes to maintaining the desired quality and consistency of the powder material.

The problem with high-density materials is their tendency to blind the screen deck when using traditional ultrasonic sieving solutions. Other screens deblinding solutions like sliders or ball tray decks don’t provide the efficiency to keep operations running smoothly.

The VertaBrute Series by HK Technologies is a cutting-edge powder sieving solution that provides numerous advantages to tackle these screen blinding challenges in your powder processing.

Boost productivity and cut costs and downtime in operations.

Simple design elements, such as quick screen changeover, keep powder processing operations moving. A screen frame securely holds a loose wire mesh cloth above a fixed wire mesh, eliminating the use of any adhesives on the screen deck. Operators can store a variety of screen mesh sizes in-house and can switch out the loose mesh screen at any time, providing the ultimate flexibility in powder processing.

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?

Eggs and Potato Chips; Shrinkflation and Slack Fill; and Vibration, of course!

By Craig Macklin

Very proud father here today! This morning in the kitchen of the Macklin Family, there took place a scene featuring the current economic condition, consumer package goods, and industrial vibration, birthed by the amazing breakfast food: eggs. 

I had just finished cooking and cooling a batch of hardboiled eggs (yay, protein!). My glorious-wife-whose-fantastic-shadow-I-walk-in picked one up to peel and noted, “These are small eggs.” So attuned and observant is that one. 

I replied, “They indeed are. What size does the package say?”

“Large,” we found. Same as we have always bought.

Side note here:

Just a few months ago, I noticed that the Large eggs were bigger than I thought they should be, and they didn’t taste that good. Almost like somehow the same amount of flavor in a Large egg got put in an Extra Large egg and got diluted. Oddly, I thought the small Large eggs we had this morning were quite good like the flavor was concentrated. If anyone has facts on egg-making science to explain this, please don’t tell me. I might swear off eggs.

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…
