This is a quick video on the new gravel pump package. Capable of pumping up to 4" sphere. Can transport material over 1000 feet above the water level. It can pump around 5 to 20 yards per hour. Weight only 1000 lbs and is 48" long, 26" wide, around 4 feet tall. Not sure on the price just yet but roughly 25K less the primping system. We should be able to have a turn key system for 32K Typically purchased by contractors and different lake associations. ... See MoreSee Less

Not sure on the build cost. Back 10 years ago we talked about 30 to 40 K Now a-days at least twice that. Not sure if we are going to go forward with the project not enough demand. Unless we get a lot of offers to build them
This crusher is awesome, hope I can get one someday
We installed the belt guards todays and the machine looks a lot safer. We are taking it out in a few weeks to see how it performs in a real mining conditions. ... See MoreSee Less

Yes we should have worn a mask !!! I had a sour thought the next day.
We are going out to test site a few weeks from now and yes you do not want to breath the dust. We only ran a few buckets and I did feel it in my thought so alway where a respirator.
Mark Keene would love to test it at my hard rock mine !
I went out to an AMRA outing in Barstow, Ca. Area and took one of our DW212V dry washers and did a quick video. I figured I had not used a 12-volt dry washer in years, so let's go out and try it and see how it works. To be honest, I was blown away. This machine did much better than I thought. It was easy to set up and operate, plus it was quiet and performed exceptionally well. It handled more material than I could shovel. When I was out there, there were a few other Keene DW212V dry washers out there, and all I heard was that everyone loved their Keene DW212V. We found some decent gold, especially for only running a few buckets of dirt. I even grabbed about some of the tailings and panned them out when I got home and only found a few fly poops. The 12-volt motor ran cool and only drew about three amps. I am proud to have my name on the machine, and it is all 100% American-made. ... See MoreSee Less
