    DRYWASHER USING A DC BLOWER INSTEAD OF A GAS BLOWER

    I really like the quality in workmanship in the Royal Drywasher. What I do not like is using a gas powered blower. Gas, Oil, Noise and Environmental Impact , but mainly the noise. Has anyone tried using a 12 DC blower such as this blower below? This blower is rated at 550CFM, 1600 RPM, at 9 Amps. Most gas blowers are in the 450CFM. The entire unit is less than 10”x10”x10”. Would be very easy to adapt a 3” output pipe to the blower.

    Those that operate a DW and use a gas blower I am wondering if you use it full throttle, half throttle, etc? If I can lower the CFM this will lower the Amp draw.. Would be very easy to make a rheostat to control the RPM to lower the Amp draw as well.

    A setup like that could definitely work. The key thing would be controlling the dust around the blower. 12v blowers can be expensive so that would be one drawback.

    One benefit gas engines have is the heat they give off can help in removing any moisture in the material your tossing in.

    That vid is interesting, although I wonder why they decided to use two conveyor belts in their design. Too many moving parts to worry about IMO.

    You can easily use an 18v cordless leaf blower to supply your DW.
    You will also need a couple of deep cycle 12v batteries wired in parallel for a long lasting power supply.

    The leaf blower will run slower on 12v but still should produce enough air velocity to power the DW.
    If it still blows too hard your rheostat idea should take care of that.



    Happy GP!

    But will they process the dirt that a gas / electric power drywasher will process? From what I read they will not.

    i run my dry washer at about half throttle, maybe less, depends on soil conditions.
    the best part of using a gas powered blower is that you can make it into a mack vac.
    its a very handy tool. almost always the best gold is on bed rock or in the crevices.
    many areas i go to i vacuum up the bed rock and find more gold that way than digging all day.

    Nope... Not sure if they have one in the plans... But their equipment is quality through and through.

With the blower motor being a shaded pole motor controling the RPM is very easy with a rheostat.

    This is the 120v blower motor, looks like a gas blower housing.

    Where did you find that blower? I've been looking for something similar for a project I'm working on.

    GoodyGuy, here you go. You will need to seach the entire site as they have many styles of, CFM, RPM, Voltages, $$$, Etc. If you plan to be able to contriol the speed with a rheostat you want to look for a Shaded Pole motor, Stay away from capacitor start motors. Search Results - GlobalIndustrial.com

    Saw this on the Arizona nuggett shooter forum, this would increase production


    i have a large industrial dry wash for sale $300
    this is big & heavy & eats material at a very good rate
    i just re clothed the trays ( theres 4 of them)
    the trays are 5 feet long by 2 feet wide
    she will need some finishing touches like more welding on the legs & set up
    it works great on a small trailer to heavy to move around,,,
    & you will have to decide on the power drive ether a 110 motor or a briggs & possibly a feed conveyor would be the cats meow ..
    i do have a 5 hp briggs i would toss in for $40
    you must be able to pick this up in golden valley az by kingman & will need a pickup or trailer
    feel free to give me a call for more info 928-200-9446

    this would work great for someone with a claim
    thanks for looking

    Sorry I had looked at so many motors on the net I thought that was the site. These are the 12DC blowers but they have them in 115 volt. You may find them on Ebay cheaper as I had, but I decided to move a different direction and did not save that info...
