Air Operated Conveyor Provides Solution for Glue Pellet Transfer

As companies move to other facilities or are expanding inside their own, sometimes you have to get creative with your system. In this situation, a paper facility had to move their glue line to make room for another project. The system included a transfer module for moving hot melt pellets from a storage bin into a hopper where it was heated and applied.   In the move, they could not locate the transfer module close enough to the glue line for safety reasons. They contacted EXAIR to see if we could help.

In discussing their layout, the best location would be to place the transfer module on the other side of an office pod but the transfer module could not move the hot melt pellets that distance. They needed to move the hot melt pellets about 20 feet horizontally and about 6 feet vertically to reach their glue line hopper, something an EXAIR Line Vac can accomplish. We decided to use a model 6083 1 ½” Aluminum Line Vac to help out. The conveyance rate would keep up with the transfer module, and it had enough power. The pellets would be transferred to a nearby bin by the module. Then the Line Vac would move it from the bin, over the office pod, and into the hopper on the other side.   With the transfer module out of the way and the hot melt pellets still feeding the glue line, they were able to continue operating the system.

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.

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…
