Since we cannot get out into the field to prospect properly right now, figured we'd share with you a piece of equipment we use for testing in our garage and also in the field for hard to get to places. Its great for hiking in, testing several locations and then coming back with larger equipment!!
Hope everyone is well, stay safe!
OK, so this time around, I have made things a LOT easier to work with, and expandability is key here. Sure, it's not huge, but for a portable system, this should work great.
The key thing here is that I wanted a system that could be printed with little to no waste material, and yet have the structure and strength to hold up for a long time. This is what I have come up with so far. This will likely be my last design for this version. I'm only tweaking a few dimensions here, as well as making new modules that can be added to it.
Modules are 276mm long by 104mm wide, max height of 106mm (virtually) unlimited stackability Use modules in any order you want Use whatever sluice mat you want (to a point) Best used with a 5 gallon bucket (self-recirculating water system) Current Modules:
Feed hopper Mat tray Bottom Support
Key note here is that those modules, even with the tilt, print FLAT on a printer, and unless something drastic changes, will require NO supports. That means nothing to clean up after the print is done. Pull it off the printer, and use it right away!
The cutaway view shows you how it currently operates. I did away with the "G-Force" drop whatever that the Gold Cube has. I wanted better flow, and didn't think that part was completely necessary. Some of those angles might change by the time the final version rolls around. I am still waiting on my four 200GPH water pumps so I can physically test flow rates.
I know this is still very small compared to a lot of the others that you can shovel hundreds of pounds a day into, but this is meant more for fine cleanup or to run pre-classified material through, although this should be able to do a bit of classifying on it's own.
Also, as I design more modules, I might include a couple modules that will spray wash and classify before sending down the smaller material to be run over the mats.
I would also like to design a sort of trommel as one of the modules. Would have to be geared to run off of some water pressure, so I don't have to include a motor and all the electronics and extra building parts that come with it. This is one part that would have to be made from metal, as anything printed would get destroyed very quickly, so I'm still contemplating this one. Remember, this system isn't meant to drop boulders into. I'd say you can safely feed in no larger than 8-mesh material. Depending on water flow, you might get away with 4-mesh, but I wouldn't count on it.
More info coming as I get more work done, and get a chance to print some physical models.
I'm not much of a sluicer. I'd rater be looking for nuggets with my detector. I like gold I can pick up with my fingers lol. My wife bought a small Keene sluice box several years ago and we set up a recirculating system at home where we could run some dirt at our leisure just for fun. I never really liked my home made set up. Although it worked it was slow..It was like a mini high banker made with stuff I got at the local hardware store. I was wanting something more efficient. In my search I found Gold Fox USA. There is also an Australian version that is the same company with a dealer who distributes for them in Oz.
I wont go into a lot of boring detail...you can go to their web site and face book page or youtube for that...However I would like to say that so far I am very happy with this little set up. I can run unclassified material through this sluice extremely fast. The trommel is five inches in diameter. I've only used it three times so far and time will tell on how durable it is but it seems to be very well built. The company has many different sizes and options available. They are fast and get the product to you when they say they will. If you have a question Kelly the owner will get on the phone and answer it for you.
The Lil Monster Deluxe comes with a 12v 2000 GPH pump. You supply your own power. I am using a RV deep cycle battery that I had laying around. I also bought a 700 GPH 12v pump and am using the two pumps together. The reason being is the material I am running is mostly clay and I wanted more water to help break it down. The only thing you have to watch is that the jets that supply the trommel will get plugged with organic material. They are easy to clean. In fact if you turn off the water supply to the hopper so it feeds the jets only...the water pressure is enough to flush them clean most of the time. Give them a look.
