Taming The Dust Cloud With EXAIR Atomizing Spray Nozzles

Have you ever dropped one of your nice dinner plates on a tiled kitchen floor? And noticed how they seem to go in slow motion as they hurtle to their doom? I never cease to be impressed at how far some of the smaller pieces can go. I recently had to replace our oven, and I found broken dishware shards (and an impressive amount of trash scraps, pet toys, and ‘dust bunnies’) all the way against the back wall.

Curiously, as small as the pieces can be when a dinner plate meets its end, it started its life in even smaller pieces…as a fine ceramic powder, pressed into a mold and heated to a temperature that is WAY hotter than when the server at your favorite restaurant warns you that plate “might be hot.”

I’m writing about this because recently, I had the pleasure of assisting a maker of ceramic dishware with a messy little problem…this fine ceramic powder is moved from where it’s produced, to the various mold stations (dinner plates, salad plates, saucers, etc.) on a vibratory belt conveyor. The vibration keeps the powder loose and homogenous, both of which are extremely important to the molding & firing process. It also causes a cloud of dust to rise along the entire length of travel, and they wanted to minimize this. Their chemists had told the engineer who called me that they could live with a small amount of moisture, as long as it wasn’t enough to make the powder clump up – this would evaporate out at a point closer to the molds anyway.

This was an ideal application for the EXAIR Atomizing Spray Nozzles…they produce a fine mist of liquid that is precisely controllable…one Model AW1010SS Internal Mix, Wide Angle Round Pattern Nozzle was installed near the beginning of the line, and once they find out how long it takes the dust-suppression supplied by the misted water to evaporate away, they will install more nozzles accordingly.

EXAIR Atomizing Spray Nozzles are a perfect solution for dust suppression.

As Seen At The County Fair

Have you ever been in a public place and noticed one of your company’s products in full view of everyone passing by? Those of you who work for car manufacturers, soda bottlers, or snack food makers (like my three friends that I had this conversation with recently do) may not think it’s a big deal (my friends indeed didn’t), so you’ll have to forgive those of us who work mainly in industrial or commercial markets when we get excited to see something that came from The Shop, while we’re walking around the County Fair.

Years ago, I worked for an industrial weighing equipment company. Every year, we were asked to provide a scale for the County Auditor’s booth at the fair – people could step on this scale, and get their weight automatically printed out on one of the Auditor’s business cards. It was a neat little setup, and my friends who recognized that it came from my employer would all crack wise about how obviously inaccurate this scale was. Since I was the one who calibrated the scale, using test weights that I was responsible for having certified by the state, I knew that the numbers on those printed cards said a lot more about the availability of deep fried candy bars on the midway, than the intrinsic accuracy of our precision instrument.

When I go to the fair this summer (and I will, and not just for the deep fried candy bars), I’m certain it’ll be hot that day…which means I’ll have my eye out for the cooling stations that are always set up along the midway, providing a fine mist of cooling water. In addition to a brief respite from the summer heat, I’ll also be looking for EXAIR Atomizing Spray Nozzles, as this would be an ideal application for our External Mix Atomizing Spray Nozzles. They provide independent control of the liquid flow rate – which will be determined solely by the liquid supply pressure – and the air used to atomize the spray: varying the air pressure won’t affect the amount of liquid; only the size/shape of the flow pattern.

Depending on what you need to spray, how much (or little) of it you need to disperse, and over what kind of area, we also have highly efficient Internal Mix designs, and, if your liquid isn’t able to be pressurized, we have Siphon Fed Spray Nozzles as well.  We recently added No Drip options to all models as well, to conserve expensive solutions, and/or to prevent inadvertent stains, runs, etc.

They’re all available in a variety of narrow and wide angle, round and flat fan patterns. For more information, feel free to give us a call.
