  OK TIM,
   You have given me an idea here. Since I am a small operation at this time, trying to work hard rock with two people is tough as I am sure you know.
   Right now my remaining (handy) ore is on a trailer. I think we will shovel the material into a small elevated cement mixer. Wash the ore and tilt off the wash into a Keene High Banker. Then when we start getting cleaner water dump or feed all the mixer contents into the high banker, what comes off the grizzly will be captured and sent through the grinding process and on to the table.

Well, you are one up on me in man power when I first started, so with that you are ahead. What you are doing now will work just fine but have you thought of the following. Build a wash trommal with two mesh screens, one will be 40 to 80 and the other 80 to 200. With your now clean and sorted material run the rough over the table. At 40 to 80 mesh that M7 will do 1TPH. Now run your 80 to 200 mesh middlings over the table multiple times. End result a little less headache and less chance of the water in the sluice part carrying away very fine gold.

Tim,
    Thanks again. Not only have I thought about a trommel I have been looking for used ones. But building one to my needs may be the best way to go.
Thanks
Bill

Building your own equipment is the best way to go. At this point in my operations the only thing I buy is material to build my equipment. Each one of my propertys have different needs and there is no such thing as one size fits all equipment. Just remember, when you build something for one of your propertys that one of these days you will need to move it some place else. So build it so that it can be changed without any propblems for the new location. Like on my trommel, I can change the screens to different mesh without out taking the unit apart and even reconfigure the water path and jets for different types of material. I can also insert a hammer system into the trommel that will allow the unit to breakup clay balls.

Hi NV Prospector

                        Is that a water sluice you're talking about ? would like to see some pickies of that one ?  because most of Australia has very little water, a very common method of panning for gold dust is to dry blow .    Most dryblowers are mounted on a trailer type arrangement with a motorised shaker and blower , very messy and dusty . there are smaller portable drywashers also . "pictured " and a field day out

I am very familiar with with the use of dry washers. We in the southwest, like you, have a similer issue of little to no water. When I am working a possible new prospect that is the primary way I do my searching. But when I am working a deposit that I hold the claim or patent I will get the water use and waste permits and run settling ponds on a recirculation system. A trommel is just a sorting device that can move a large amount of material and get it ready for the slurry pump. The M7 is just a very fancy shaker table that has to many adjustments on it. I will dig up some pictures of the equipment that I use so you can get an idea.

Thanks again.
    Clay is a very big "Sluice Robbing" problem for me also. How does your hammer system operate(via water,A.C,gas,Etc.)?? I would love to see some plans or picks if possible of the whole system
Thanks Bill

The hammer system is a very simple solution taken from what placer miners do all over mexico and the southwest in the late 1890's to the 1930's. All it consist of is a metal bar running through the center of the trommal for the entire length. From this metal bar are hung chains with harden steal bars (hammers) attached to the ends of the chains. The end of the hammers are with in a 1/4" to 1/2" from the side of the trommels inner wall. When the trommal is in operation the hammers pound the clay balls into powder.
