The Gold Claimer Brand Gold Trommel/Concentrator (Part 1)
(Gold Claimer's gold trommel/concentrator.)
"It Works Good"
I have fellow New Mexico gold miner "Rattlesnake Jim" to thank for this post, since he's the one who clued me in about the Gold Claimer brand gold trommel/concentrator. "Jim" is as experienced as they come when it comes to all things mining and he says he's been using this this piece of mining equipment on his claim for about 2 years now.
Like many veteran gold miners, "Rattlesnake Jim" tends to cut to the chase when it comes to making his points. He puts his opinion of the Gold Claimer trommel this way: "It works good."
Since I know that "Jim" knows what he's talking about, I'll just leave it at that.
Here's What You Should Know
For the remainder of this post I'll drop the concentrator tag from Gold Claimer's trommel since virtually every piece of small-scale mining equipment out there "concentrates" gold. Even the lowly gold pan is a concentrator of sorts. So much for the finer points...
Here's what you should know about the Gold Claimer (somewhat paraphrased from the company's promo materials):
Can be Used in Wet or Dry Placers
The Gold Claimer is a self-contained unit that's tailored for small-scale mining operations as well as testing and sampling. This unit can run from 2-8 yards of material per hour at a very high efficiency rate in both wet or dry placer situations.
Did I just say dry placers? Yep, I did indeed. The Gold Claimer employs a unique water supply and reclamation unit that allows you to run this trommel where there is no water available. In other words, the Gold Claimer can recirculate your existing water supply.
By the way, you should know that the length of time you can actually recirculate a limited water supply using any piece of mining equipment is somewhat dependent on whether you can add additional "clean" water at some point(s) during your mining operations. I've used recirculating equipment systems in dry areas in the past and they work great until the recirculated water gets so dirty it takes on the consistency of mud. Then all gold recovery bets are off my friend.
Oscillating Sluice Box
The Gold Claimer's hopper uses an adjustable water valve to "slurry" gold-bearing material before it enters the trommel itself. Lifters then tumble and break up the material as it enters the trommel and an adjustable-valve water spray bar sprays the material the entire length of the trommel drum.
Next, the material is classified or screened by 3/8” diameter holes where any material smaller than that gets washed down onto an oscillating sluice box and any larger material works its way to the end of the trommel. A nugget trap then catches any heavies or coarser gold while lighter material is discharged from the tail cone to the rock chute and discard tray.
3 Stroke Settings for the Sluice
You can set the Gold Claimer's oscillating sluice to one of three stroke settings: stationary, short, or long strokes (1-15 pulses per minute depending on which setting you choose). The removable sluice box is lined with artificial turf (for fine gold entrapment), standard riffles mounted on expanded metal, and 4 toggles to secure these elements.

Any lighter material that gets washed off the sluice goes into the de-watering screw, which is the most efficient means of removing solids from water so that you can recirculate that same water. The unit's auger is raised from the bottom and this forms a "black sand trap" as well as a secondary gold recovery area just in case your water flow is too fast and high over the sluice.
More to Come
I'll have more on the Gold Claimer brand trommel in my next post. Please note that I am not connected with Gold Claimer in any capacity nor am I receiving any compensation for writing up their gear. (However, if Gold Claimer reads this series of posts and wants to make a donation to "Bedrock Dreams," I sure as hell won't stop them!)
I wish all of you out there health, wealth, and much happiness. Get lots of yellow in those gold pans...
