Conveyance Testing? We Can Do That!

Over the past month I have spoken with many customers who all had a similar concern.  Will the Line Vac actually convey my product?  Generally, the Application Engineer team can pool our experience together and get a pretty good feeling on if the product will be able to be conveyed the needed vertical and horizontal distance.  We can even give some estimates on what rate of transfer for the product.

In some cases though, the customer prefers to have some hard evidence to showcase to their leadership that the product will work and fill the need they have.  In those cases, as long as the product does not present a disposal hazard or respiratory hazard then we can probably take a small sample and do some testing then provide images, and possibly even some video.

Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

We may not be able to set up the exact product path that your system will require, we can generally convey a simple vertical with some horizontal.  The list below gives just a few examples of the products we have tested:

  • paper scrap
  • medicine tablets
  • ground rubber
  • dry ice
  • seasoning/spices
  • die cut scraps
  • steel shot
  • tumbling media
  • candy bars (These were delicious, please send more!)
  • nutraceuticals
  • plastic caps
  • plastic parts
  • packing peanuts
  • coffee beans
  • adhesive backing paper
  • cat food additive
  • bolts
  • springs
  • Doo Hickeys (okay, maybe my daughters made me watch Little Mermaid recently.)
  • sand
  • nuts/seeds

The list could go on and on.  The point is, if you are questionable on how well a Line Vac would work with your product, don’t let that deter you from reaching out to us and speaking with an Application Engineer.   We’ve done lots of product testing, and we will all share our experiences with you.  Also, we have conveyed a Cincinnati-Style Chili 3-way.  You can see that in the archives under Will It Launch.

The Rate Is Right?

This morning, we played our own little version of a popular segment of the game show “The Price Is Right,” right here in the Application Engineering department. Brian Farno (our manager and host extraordinaire) presented us with a question (that he already knew the answer to after speaking with a current customer):

What would you expect the conveyance rate to be, for an EXAIR Model 6083 1-1/2” Aluminum Line Vac, conveying hot-melt glue pellets, across a total distance of 15 feet vertically & 100 feet horizontally? (And please note we normally have a bulk density in lbs./ft3 and/or other associated information about pipe bends, product shape etc. – but we took our best shot at it anyway).

Our office doesn't look like this.  I kinda wish it did, though...

We didn’t have those cool podiums to stand behind that recorded our answers on the screen, but here’s what we came up with:

Russ Bowman: 5 lbs per minute
Dave Woerner: 10 lbs per minute
Justin Nicholl: 8 lbs per minute
Professor Penurious: 1 lb per minute (Insert $1 bid joke here)

Now, we had all referenced our wealth of data charts for conveyance rates with our Line Vac product series. We used several very different materials over a few different lengths/heights, and use that data to estimate what a user might expect to see, based on how close their application is to our actual test conditions. I actually used this data for my answer – a 1-1/2” Aluminum Line Vac conveyed tumbling media (64 lbs/cu ft; the lowest bulk density material we tested for) at a rate of about 5-1/2 lbs/minute, going 20 feet vertically.

Left: hot-melt glue pellets.  Right: tumbling media

Turns out, Dave came the closest without going over: they were actually getting a little over 11 lbs per minute…again, going 15 feet up and 100 feet over. The user was so pleased with the results, they’re incorporating a Line Vac in a similar application, involving hot-melt glue pillows. We’ve now added their data to our database and are pleased with the knew knowledge.

If you have an application involving hopper loading, bulk material conveying, chip removal, parts transfer, etc., and would like to find out how an EXAIR Line Vac can help, give me a call. We might both be impressed with the results. Come on down!

Professor Penurious, by the way, is still concentrating on hosting the game shows.  Stay tuned…
