Meet Our Super Max !

We are extremely excited to present the next generation of a dredge designed for the recovery of super fine gold.  Over the last 70 years the Keene family has been the world leader in portable dredging and dry washing equipment. The first sump system and triple sluice was developed on an eight inch submersible dredge built by Ernie Keene in the early 1950’s. Ernie also built our now world famous triple sluice dredge back in the early 1970’s. In the late 1980’s we introduced the three stage sluice system, as well as many other innovative firsts.

Here we are in 2016 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.

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.
