Keene Gold Dredge with New Technology That recovers super ultra fine Gold

This is the next generation of a dredge technology designed for the recovery of super ultra fine gold.  Over the last 70 years the Keene family has been the world leader in portable dredging and dry washing equipment.

Here we are in 2017 and we have developed the Super Max Sump Dredge. This beast outperforms all other dredges in the world for micro fine gold recovery. The entire dredge was built with state of the art technology including new floats, frame, pumps, power jets and more. The sluice box is oversized to control the material and allow the fine material as it is classified into a slower velocity zone.

We have found through years of experience, testing and customer feed back, that the best method to collect gold is to alter the sluice box into different riffle sizes and expanded metal classifiers. We have also found that the use of woven wire creates greater drag and deposits the smaller material much more effectively and efficiently than a traditional punch plate.

 The oversize 8 feet by 24 inch wide sluice box will capture the majority of heavy material and disseminate the clay conglomerate providing a smooth slow slurry as it is classified into the sump, which is located at the end of the main sluice.

The sump was engineered by computer aided design, optimizing seamless flow of fine material that is being drawn into the sump and vacuumed out into the side boxes. One of the main keys to making the sump work correctly is to use the custom made, heavy woven wire to create the proper drag on finer material which allows the coarser non value material to pass through.

The sump creates a slight negative vacuum on the screen that pulls 100% of all the finer values into the sump. From there it is pumped into the elevated side boxes. By pumping the minus 1/8th material into a controlled flow environment, all the super fine gold, up to 500 mesh, can be recovered from the side sluice boxes.

Super Max gold dredge

The Side boxes are constructed with a 10” wide header box that flares up 17 inches wide and is 5 feet in length.  The sluice is lined with our world famous Miracle Mat and is partially covered with expanded metal.

As stated earlier, the new float and frame assembly is also a newly designed. The frame is precision made on a C&C Mill and water jet machine and constructed out of lightweight tubular steal for superior strength.

The floats are by far the most advanced floats in the industry, providing a long tapered nose with cupped runners. This allows the dredge to cut through fast water effortlessly. Constructed of cross link polyethylene material with brass inserts that are cast into the top of the floats for securing to the framework of the dredge. Did we mention that the universal frame sections makes this dredge a snap to set up and disassemble?  You will need only a 9/16th wrench and socket to put this frame together.

Our standard Super Max model is powered by two 10 horsepower, Briggs & Stratton Vanguard engines; our new PHP500 pumps that provide superior performance at depths to 20 feet. The Super Max can also be powered by one or two GX390, 13 horsepower engines for greater depths.  The pumps are equipped with a 1 inch accessory port that drive a pair of 2.5 inch suction systems.

 The systems are outfitted with ball valves that are equipped to meter the flow to the side sluices with precision. You can use the side sluice as a primary clean up concentrator. What does that mean? Well, traditionally you would have to haul several buckets of concentrates and process the material on a separate unit, which could take hours, depending on the concentrating equipment available.

With the Super Max, cleaning the concentrates is a breeze! Simply take the concentrates from the main sluice and run them through the side boxes. The result is at the end of the day you have a nominal amount concentrate which completely reduces the need for secondary clean up equipment.

What we have now is two machines in one. The dredge to collect the material up into the sluice box to grab any of the larger gold. Then New technology that separates the ultra fine gold in the upper smaller sluice boxes.

And then the second best part of the machine is its concentration process (clean up) that separates the fine gold. No more hours of clean up and panning the concentrates. You still have to pan your concentrates, only you don’t have multiple five gallon buckets to do.



Recover 100 to 500 Mesh size Gold

With the New Technology on our Super Max, you can expect to recover up to 500 mesh size gold.

Did You Know you are losing up to $600 an hour if you’re not using the Super Max?

Studies have shown, depending on the material being processed, you are probably losing up to $600 and hour in ultra fine gold. Our new technology is recovering ultra fine gold up to 500 mesh size.

Research Studies Show recovering between 25% and 40% an hour more than any other dredge on the market!

So are you using a cheap China dredge? Chances are you are losing enough gold in 6 days to pay for this dredge brand new!
