The Importance of Product Testing for Fine Mesh Screening

By Jeff Hochadel

Many times a potential customer will call our office or email asking for a quote and delivery on a specific type of equipment. Our standard response involves asking the customer a series of questions ranging from what the product is, estimated throughput rates, percentage of plus and minus screen size, and others. We typically also ask for an application data sheet to be filled out. All this helps remove the guesswork out of equipment sizing.  Sometimes the customer thinks he knows what is required based on past experience or what someone else has told him he needs. While many times these assumptions may be correct, we want to make sure what we sell the customer will ultimately meet or exceed their expectations. While filling out forms and asking questions definitely assists in proper screener selection, I have found asking for a sample of the product for in house testing eliminates all the guesswork out of the equipment selection process. If time permits and the customer requires we can also send out a demonstration model for a short in-house testing period.

Running tests on a sample or sending out a demonstration model will ultimately remove all the guesswork out of equipment selection. Read More…

Using Vibration to Reduce Material Cost and Increase Profit Margins in the Plastics Industry

By Katy Sabo

Industrial vibration can be found in multiple areas of plastics processing and can help reduce the costs of materials and increase profit margins substantially. With the use of equipment such as vibratory screeners, companies are able to reuse regrind and efficiently sort out the usable material from that of which needs to be discarded. There are other ways that industrial vibration factors into the processing of plastic products, read on to learn more.

What exactly is “Regrind?” Regrind is a term that seems self-explanatory and if you guessed that the it applies to mechanically reduced plastic components/products, you guessed right. Much of the plastic waste used in this process usually comes from a pre-consumer source, for instance processed scraps or even unused thermoplastic materials from injection molding. Read More…

What You Need To Know About Screening Media: Woven Wire Cloth, Part I.

By Jack Steinbuch

There are a wide variety of screening media that can be installed in vibratory screeners.  Our challenge is to select which type would be best suited for your application.  You can refer back to my blog: Importance of screening data from May 2013 to review the technical data that would best assist us in making screener recommendations.  Some of this data would also be appropriate for selecting screening media. This blog is the first in a series that will be 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.

Woven Wire Cloth

This is the most common and widely used screening media for many applications including scalping, sizing and dewatering.  Woven wire cloth is typically designated as space screen (clear openings) or square mesh.  Space screen is the inside dimensions of the opening which should be further designated with a specific wire diameter.  Please note that the wire diameter doesn’t affect the screen opening Read More…

How You Can Reduce Plug Blinding During Screening

By Jack Steinbuch

Blinding is when there is a decrease in the open area of a screen due to coating or plugging.

What is Plug Blinding?

We will focus on plug blinding as it has become more prevalent due to the increase in recycling. Plug blinding occurs when you screen material containing particles with irregular shapes. Think of candy corn: if the pointed end falls into a screen opening and then gets stuck or plugs the opening, it can prevent the fine material from passing.

Eventually, the screen section can lose its screening effectiveness as more particles plug into screen openings. Since this material wedges into the screen opening, the vibration energy used to screen the material isn’t always sufficient to knock them out of the opening. For example, the recycling of plastics creates irregularly shaped materials that can plug openings, thereby adversely affecting screening. Our challenge is to find a way to reduce plug blinding to keep our screening efficiency and reduce the downtime cost to clean the screen deck manually.

Experiencing the Grit and Glory of the Industrial Vibrator Industry

By Katy Sabo

There are many aspects to the working at The Cleveland Vibrator Company that teach you valuable industry lessons, especially when you are considered a “rookie” or “newbie” in the industry. I began my journey into the Industrial Vibrator world this past December and I am surprised myself as to how much knowledge I have gained thus far – particularly the impressive span of industries where vibration is highly valued in order to efficiently move materials through plant production. Being the Marketing Associate, it is part of my job description to photograph every piece of Fabricated Vibratory Equipment that leaves our facility. Coming into an industry that was completely foreign to me, this job detail quickly became incredibly beneficial in my learning process about Industrial Vibration and where I could find it in use.

My first experience with photographing Vibratory Equipment happened within my first week on the job, I was asked to video the testing of an EMS Electromechanical Vibratory Screener. Read More…

Vibratory Feeders & Screeners: The Affects of Force, Acceleration and Frequency

By Jack Steinbuch

We often receive calls from customers that need to make adjustments to the product flow in their vibratory feeders or screener/feeders.  Our challenge is to determine what style equipment is being operated to provide the appropriate options.  The following are three basic drive options which produce linear force that can be used to power vibratory feeders or screener/feeders.  To clarify, a screener/feeder is designed to feed the material with that same vibratory action also serving to help stratify the material – Read More…

Cleveland Vibrator Co. Industry Watch: “Everyone Needs Vibration, They Just Don’t Know It Yet.”

By CVC Team

Eighteen years, hard to imagine, harder still to believe, where does the time go.  1996 was an interesting year for me, I was wrapping up my studies at Cleveland State University looking forward to graduating with my engineering degree. I’d just spent six months with my Army Reserve unit deployed to Haiti supporting the U.N. mission there, returning in time to start winter quarter.   I still remember sitting at my dining room table studying for an upcoming test and getting a call from Glen Roberts of The Cleveland Vibrator Company.  I guess I was engrossed in studying and really wasn’t 100% into answering the phone, I almost hung up on him thinking that he was a telemarketer!

I never really anticipated staying with one company for 18 years.  A quick look on the internet says that the average male has eleven different jobs during a working life time; guess I’m dragging that average down a bit.  So what’s the attraction?  Read More…

Low Cost, High-Frequency, Screen Deblinding – Turbomite Deblinding System

By Jeff Hochadel

­­Several weeks ago, I was reading an article in one of the technical journals discussing the variety of ways to eliminate screen blinding on vibratory equipment. The article discussed a number of “old school” solutions such as rubber balls, clean rings, spray nozzles and brushes. These methods have been around for decades and produce a low to moderate level of success in keeping the screen surface from blinding or clogging. The article also discussed the most effective solution for screen deblinding – Ultrasonics. While it is the most effective, ultrasonic deblinding systems are also the most expensive. If you are not familiar with ultrasonics Read More…

The Importance of Getting All the Data for Screening Applications

By Jack Steinbuch

We receive numerous requests for Screeners where the effective screening area has been specified by the customer.  While a decent amount of these requests work out to the best of our knowledge (since not everyone is willing to admit that they may have erred in their request), we do offer to review the application to confirm that the screening area is adequate if sufficient data is provided.

Our challenge in this instance is to get the customer to provide us with the information we require to determine the optimum size, and Read More…
