Wow, nice.

Keene Trommel Test # 8
Well we are just about ready for production and our last test was flawless. Both the water drive motor and the 12 volt system work great. The Water drive motor is my favorite due to the fact you can use it like a high banker and relocate the machine hundreds of feet away from the river. Providing you have the right Keene pump and some oversized pressure hose to keep the friction loss to a minimum.

The 12 DC version is great for working near the waters edge and the silent operation is ideal for family settings and also when you want to maintain a low profile or work in areas that do not allow gas engines.

The Trommel does not come with a sluice box however most any sluice will work with our sluice box extension. The Trommel provides the ideal flow for a sluice with a highly classified material and a controlled water flow. However nothing works as well as the A52S Sluice box.

The prices are a little higher than we hoped for however in Biden economy everything is so expensive. Raw materials plastics platting steal aluminum and going up every day. "Lets Go Brandon"

KT10DC 12 pumps and 12 Drive system is $2195.00
This comes with the 2 pumps so all you will need is sluice box sluice extension and battery.

The KT10WD Water drive motor is $2295.00.
You will need the sluice box, Sluice extension. A good quality pump that has good head pressure like our P90GH motor and pump package. The P90gh provides up to 100 GPM and the head lift is up to 160 foot head. Trash pumps or semi trash pumps may not work due to the low head lifts.

The Sluice box extension $149.95 Comes equipped with Miracle matting heavy expanded metal classifier screen and rubber flap.

Trommels and high bankers are similar in production. The advantage that a trommel provides is better in clay, hand packed and conglomerate rock. Also in material containing a lot of weeds. It is a easier to use since there is less handling of the material. You do tend to get less wet during operations. Do not get me wrong I love high banking this is just a better twist on things. high bankers are less expensive and lighter as well. This is a lot of fun to operate and I would rather use this trommel rather than a high banker since there is less touching the material and you can see the sluice perform at all times. I can't wait to take one up north and do some serious mining.

From the videos I've watched on YT between the high banker and mini trommel there doesn't seem to be any difference in the amount of material you can run.

hello where can i buy it in europe from a reseller. thank you waiting for a reply.

I was really wanting one these!!

I can see having to run clean water being a major issue.

How much for just the water drive motor?

Keene KT10 Trommel test # 7. Patrick and I went out and did some testing on both Water motor drive and DC drive system. We tried a few things like a nugget trap however this did not work since it backed up material in the drum. This is a very good location for testing due to a verity of materials. We had some good sticky river gravels with clays, roots etc. We also encountered a strange broken slate type rectangular type gravel as well and the machine performed well in both. We learned a lot from this trip and looking forward to the next outing. We believe We are very close to the final production model. Looking forward to the next test trip, this is the fun part of job. ... See MoreSee Less

Dennis you are right the trommel excels in hard packed conglomerate and clayish material. A high banker does works about the same and for less money. However I have really enjoyed using it, It is so nice to see the sluice coming out either side makes it easy to control the load of material in the sluice. It is nice to stay totally dry and dump big rocks and all into the hopper. There is some level of a fun factor with this trommel.

The Trommel is only good for Clay or Hard pack Matrix. Otherwise a High-banker works Great...

This is custom Keene Super max 6" designed to work in a very sandy environment and heavy black sands. This is set up for a shallow water application with dead leg anchor system. Very cool dredge and this will should be amazing in the fine gold areas ... See MoreSee Less

Beta tester, I'm about to hit one of my claims in Southern Oregon. Taking a pretty good sized work party. I've got 5 nephews 😎

I miss doing this with my mama a pops

Can’t wait!! You have a buyer in idaho already!

When you say water motor, are you referring to a gas engine & pump?

I would love to have #1 of the 1st run after final proto. Very impressed with your pump repplacement and the setup package to get started.

I want to buy this equipment

3/4 to a yard per hr is not to shabby for a shovel operation. Do you have an idea on price?

I really like this mark, I herd you were in NH twin river, I would love to have talked to you, that river is my home lol. Hope to see you there so day, I love Dennis and his family. Home to me.

Looks killer !

I really like it

Would love to have one of these machines here in Australia, I am working an area where I have taken 6 grams of gold per 2 gallon bucket of dirt and have been using a pan to get it out, this machine would allow me to recover the gold so much quicker. I visited your shop in August 2016, and the owner was very kind to us and took me on a tour of the factory

😎☠️💛⭐️🔥🙌

Would like to try this machine on the Bear River day use area. I think you need to increase the length of the sluice box and install expanded metal rifles over stair case rubber matting.

Looking good love it

Plz take my money lol

Beautiful beautiful

Bad ass

Are the water drive motors ready for sale? Excellent idea by the way

You can send one to me for testing lol

We finally put the beer Keg back together. This is a Roto Mold of solid stainless steel for making our plastic parts. These are the end caps for our new trommel that have the nugget traps, belt groove and wheel grove, so with a little luck it should work fine. Everything has been so smooth so far. We will be lucky if everything goes the way we planned. This a a very difficult part to make with all of the inside detaiul and precision to get it right the first time. We use the most expensive and strongest material available called, Crosslink Polyetheline that has the highest U.V., High impact and cold resistance type plastic available. We also utilized a very special E.D.M. machine, electrical discharge machining to cut the two halves perfect. The whole idea us building the end caps is to have the versatility to allow multiple screen sizes. The cost of all of these materials and process have skyrocketed. Go Brandon! ... See MoreSee Less
