I want to make an atomizer for making micron silver powder. Anyone has experience with making one?
Welcome to us.
There are members that has built atomizers, but it is not for the faint hearted.
It involves very high pressures and to do it legally it need to be done with certified welders (I think) and so on.
Search the forum for atomizer and you will find.

In case you plan to deal with chemicals and refining here are some links to you:

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

i’m building one. Find a first rate welder first that knows what he’s doing.

It’s one of several things i’m doing including running my biz.

When i’m done and it performs to my satisfaction i’ll post it.
 
It should be noted that a simple atomizer made from off the shelf pipe fittings* and powered by a hardware store variety of power washer will produce fine powder for standard digestions in aqua regia. It is when you want to take advantage of different chemistries the super fine particle size comes into play.
* in the link Kurt posted above is a photo of Samuel_A's atomizer from pipe fittings that did not require welding.

Nice, that image had passed me by.
 
Getting there. I’m thinking i will use square bar stock for the legs then cut out square notches in the tank so the atomizer fits in well and doesn’t move around on me.

Nice fabrication work. I notice you do not have the spray nozzles threaded in yet. I always preferred fan type nozzles but you have to pay attention when you thread them in. If all of the angles and orientations are precise, if the 4 nozzles are normal to the circumference, their focus where the water streams intersect can leave a square of lesser velocity. This square is directly below the center where the molten stream of metal flows. It can result in a percentage of the particles being larger. I have corrected this by tightening the nozzles a fraction of a turn tighter so the water intersects, at that potentially square focus, in a pattern that eliminates the square and essentially causes a rotation or spiral of the flow. It may not matter, but the good news is the thread in feature allows you to make adjustments as experience dictates.
 
That is just the working portion of the atomizer. It is the critical juncture where the water flow is directed to come together with the molten stream of metal at high pressure. This essentially sits over a water reservoir where the atomized product collects.

The size and pressure of the pressure washer is determined by the nozzles you select and the GPM rating of the nozzles. More pressure equates to smaller particle size.

Are there studies on this? I would like to do more research, to determine the correct size and the pressure washer power. Also would you have any sort of blueprints, that would help a lot.
 
The size of the particles in the product you want to ship is determined by classifying the atomized dried powder through screens. The higher pressure determines how much oversize you are willing to re-melt.

Studies on this design, I do not think so. This is a project which a few of my clients have ventured to make to make fine powders in a cost effective manner. This particular piece was made of 300 series high pressure (3000 psi) stainless steel. My first proof of concept model was made of pain steel pressure fittings and it worked fine but it also rusted.

If you want guarantees and exacting drawings you will have to resort to the manufacturers charging upwards of $250,000 to make these. The link provided above by Kurt will give you more details.

The concepts are the same, this one just lacks a fancy enclosure and nice paint job.

See Kurtak’s first post in this thread for more information. I think there are others as well buried in the forum.
