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.
