WHAT’S HAPPENING…

This is our latest test on the large 210 Dry Washer. This is after 20 plus test trips. We are basically ready for production on the 210 dry washer. We are working hard to develop a feed hopper that provides a smooth even flow of material into the 210 vibratory shaker deck screen. A smooth even flow is a key to high production and fine gold recovery. 04/18. Mark ... See MoreSee Less

Y s, the clean ip

Great video Mark. Thank you for sharing 🙏🏻👍🏻😊

Show us the clean up.

Running my Keene Mini Puffer with my crew works just fine for me! 😎

Why is it named the 210? Just curious

812 rock crusher feeding the dryer is the way to go

Looks good Mark !! Wish I was closer an able to see it work in person.

Sweet!

Kyle Secrest check this out

What a pleasure to have Patrick Keene at the LDMA Stanton Camp to show all how this monster can chew through material and capture the gold.

We are preparing for the Las Vegas gold show and we are bringing one of our super max dredges. This is a view that no one typically sees. You can see the long stringers running the length of the floats adding strength the stringers also aid in keeping the dredge going straight with the current. In theory this design should work well with an outboard engine helping the dredge come on plane. ... See MoreSee Less

Not Everything is about Dredging Las Vegas is a Desert...

Thanks that’s a great picture I’d like to see some ore crushers 🙂

Bering sea gold? Here we come

Washington St. Just lost ALL Moterized Placer Mining Sat. The 14th. The Next St the Greenies are after is Alaska! I warned everyone in 1998 that this would happen!

I saw it in the factory being built, what an awesome machine.

Sure look better than the older 8" floats held on by ratchet straps.

Does it come with a snuffer bottle?

Jochen Bergheim here us the one i said i needed, prospecting equipment in big scale

We have been out in the field for the last few days testing the 210 dry washer. The dry washer itself is working great. The feed hopper needs more work. The most important thing is a smooth consistent flow of material into the vibrating hopper. We have to make some modification on the hopper before we take it out again. Finding the time is tough. ...

The vibrator you mentioned in a very good idea we are just going to take it up a few notches we are going to make up a very powerful vibrator mount it on the hopper and transfer some of the vibration into the lower hopper as well. Make a few changes on the opening of the bottom of the hopper and Make the walls a little steeper. If you have any other thoughts call me at 8186683419

I have also looked a concert settler may add it to the bottom of the hopper if need be. Mark

So please help if you can. Mark

I would greatly appreciate any help suggestion etc. I have no problem with water-based hoppers but dry is proving to be a challenge. I did think about an Auger in the bottom to provide a smooth clean flow. The problem with that is we are trying to keep the cost of the feed hopper under 10k. and an auger system can cost up to around 8k according to sales guy I talked to yesterday. We are going to be adding some vibration to the hopper and a new grizzly bar system.

The next time you go out,let me know ... I’d like to check it out and help out ... I have 20 yrs experience in making hoppers and a couple claims to work ,... just a thought!!

Try The Old Coin Operated Beds they have a Great Powerfull Shaker that can Rock your Dirt

Do you know why Peg Legs Gold was Black ? I Do ..🤔

Good Luck ! I'm in the Mojave Desert Every Day and Every Day is Differnt !

Warning all price going up in the next week or so. We have substantial raw material cost increases. In all my years in business, I have never seen such huge increases coming at us all at once. Plus we have not really raised our prices in a few years. So buy now and save money!!!

Steal increasing 40% +
Aluminum 30% +
Raw plastics floats hopper jet flare etc.
All hoses have a big price increase
Pulleys have more than doubled
Cardboard just went up 10%

I personally think the this is a good move by Trump and it will benefit the USA in the long run. Short term it is going to be tough on everyone. Once we get our production of American raw goods back in action we all will be benefiting for many years to come.

The sad part is that shipping, cardboard, plastics are all jumping the price increase frenzy and I see this as taking advantage.

Maybe you should properly tset your products befor relising them! Everytime i buy something of keens an upgraded version comes out 2 weeks later! Is the my local gold shop or is it keenes!!!!

I just bought a feeder for the gold wheel and in setting it up it sits way of the spot you want it to be! It dosent come with instructions on where its ment to sit and the best possition to feed the wheel!!! You just leave us hangin! And we gotta waist our credit watchin you tube vids!!!! Na not happy

I coulda made my pwn feeder and saved $240 arrg! I bought it and i have to adjust it!!!!!!!!! It has no adjustment!!!!

Will be proud to spend more on American made steel and aluminum

Sure, but your online store shopping cart isn't working

Understood, thanks for the info.

i wonder why on earth the raw materials are going up 🤔

I'll happily pay more for products made in the U.S. out of U.S. supplied material.

Dam trade war! It better make gold go up!

Got to thank Trump.

Thanks for the heads up Keene Engineering, Inc.

Thank your idiot president for the prices increasing.

We are going out later this week to test the 210 dry-washer for the 19th time out in the field. We are very excited to test the latest feed hopper design as well. We preparing precise amounts of gold of different sizes down to 200 mesh and buckshot for our testing trip. I will be very interesting to see what percentage of which mesh the machine will retain. How many other companies out there do this crazy amount of testing before producing their first machine and who keep on improving on each production run. Nobody!
I have round and flattened buckshot for the first round of test. Once we have all the basic settings dialed in, we can move onto the real test, fine gold test. We hope to move somewhere, between 6 around 8 cubic yards per hour or maybe more? We are working on an old ancient seabed that contains no gold but has a variety of rocks, gravel, sand, and clay. We will be reworking our tailings with a smaller dr-washer and a recirculation system using water. We have already done a ton of testing on the 210 however, this is hopefully one of the final recovery tests we will do before, going into production on the Beast machine.

Nice design guys... !! If the header performs anything like the minimal, it will certainly deliver a very neven laminar flow. I have been looking for the next thing I need to buy to test out.. might have just found it.. lol

Nice
