Value of Industrial Vibration Part 2: $30 per Gaylord

Posted on

While not as large of a figure as in Part 1, this number can sure add up over the course of the year for many manufacturers of bulk products such as powder metals, plastic pellets, bulk foods, metal parts and chemicals who can use thousands or tens-of-thousands of Gaylords in a year for packaging their […]


Industrial Vibration to Unstick Things

Posted on

Many applications of industrial vibrators are for material flow in hoppers, bins, chutes, and pipes; or material settling and de-airing. However, we frequently come across customers that don’t work with dry bulk materials or wet cast product. Instead, they are looking to apply vibration to their process to “un-stick” their wet, sticky materials from the […]


Vibrators Don’t Damage Equipment, Wrong Installations Do

Posted on

Recently, I took a whirlwind trip through the heartland. During this trip, I had the opportunity to visit plants and equipment makers installing and using vibrators. While in the field, I encountered damaged equipment, including cracked hopper walls that had to be re-welded.  Too often, the vibrator gets a bad rap in these situations. However, […]


Grain Entrapment and Engulfment: Rail Cars

Posted on

Well, this sad news was released recently: “Worker Engulfed in Rail Car…” which made me revisit my prior post to dig into data some more.  Once again, I went to the data set provided by NPR Buried in Grain. This time I looked only for “rail car” in the incidents and found two in the […]

More Grain Entrapment and Engulfment: Hopper Bottoms

Posted on

As further follow-on to my previous post, I wanted to look at a specific subset of Grain Entrapment and Engulfment cases.  As I mentioned, I don’t think industrial vibrators and/or timed knockers are the silver bullet for preventing all cases.  However, I do think they can be effective for Craig MacklinCraig Macklin joined The Cleveland […]


Grain Entrapment and Engulfment

Posted on

Due in a large part to the efforts of NPR, I recently became more aware and educated on a tragic and horrifying issue in the Feed and Grain industry: Grain Entrapment and Engulfment.  Basically, this is the incidence of being buried and/or drowned in bulk grain.  I shudder to even think about the experience. Reading […]

Posted on

If you didn’t read Part 1: $100,000, you should immediately.  It is life changing. All set?  Great.  Welcome back.  Incredible wasn’t it? If you didn’t really go read it, you might struggle with your conscience later, but you should still be able to follow the rest of this post fine. Similar to the value of […]


Slack Fill Packaging and Economics of Marketing vs. Material Cost

Posted on

Not too long ago, I was speaking with Jack regarding a letter he was writing regarding the extra space he found in the packages of Non-Dairy Creamer Powder he likes.  His theory was that the powder product was settling after packaging and during transport, which was leaving more space in the package than was needed.  […]


Value of Industrial Vibration Part 1: $100,000/hour

Posted on

As it happens, I am rather new to this industry.  My background is primarily in the world of theoretical products and service of Enterprise Software systems and implementation consulting services.  Two years ago, the uses of industrial vibrators were pretty foreign to me and anyone that I would happen to correspond with on a day-to-day […]
