Mountain Goat Reverse Helix Trommel for gold mining prospecting

Speed up your gold processing work and increase gold recovery with the Mountain Goat Reverse Helix Trommel. This machine is rightly named because it can eat almost anything and is light enough to carry up a mountain!

The Mountain Goat is efficient because the spiral riffles inside of the tube turn and bring the heavy materials up to the high end of the tube while allowing the lighter materials to flow out of the back of the tube as tailings. This system makes the trommel completely self-cleaning, which eliminates the need to break down for clean-up as is necessary with sluice box type equipment.The spiral riffles in the trommel tube are ¼ inch deep and spaced ¾ inch apart. We suggested your placer material be screened to ½ inch or less even though rocks as large as ¾ inch will pass through the tube. There is a nugget trap at the low end of the tube which should be checked regularly for nuggets larger than ¼ inch.

The front legs of the trommel are adjustable to increase the pitch but we found that the factory setting is the best for getting fine or flour gold. The factory setting has the front legs about 1 inch longer than the back legs. Tests have shown very little loss of fine gold at this setting when a wetting agent such as Jet Dry is used in the system.

Features

The Mountain Goat can be used in a tub to recirculate the water to operate the machine. That way, the water stays free of leaves, etc. that can plug the pump. A sock slipped over the pump will also keep the spray system from clogging up. Any large tray such as a mortar mixing tub (found at most home improvement stores) can be used with 5 gallons of water which is then recirculated by the 750 gallon per hour pump.

The Trommel can also be used directly in a stream and is a very sturdy machine designed to take a lot of wear and tear!

The Mountain Goat can be set up to feed directly into the Desert Fox Gold Panning Machine to make you a one-man mining operation.

Camel Mining Desert Fox Automatic Single Speed Gold Panning Machine.

The Desert Fox spiral wheel has SEVEN separate spirals which pick up GOLD SEVEN times with each rotation of the wheel (105 times per minute). The seven spirals dump gold into the tube-shaft and into a hanging gold catch-cup. This method is far superior to other types of spiral wheels which do not pass the gold through the center of the wheel into a hanging cup. The Desert Fox wheel with its pitch adjustment and water spray system helps the operator “tune out” the black sand.

The Desert Fox is a compact, light-weight gold panning machine you can take anywhere. Weighing under 10 pounds even with a rugged folding stand, it folds up and stores neatly in its Action Packer tub. Operate it right out of the tub, or remove it from the case and use it in a stream. The Desert Fox is aptly named because it was designed to conserve water and will operate on just three gallons. It sets up quickly and easily and can run 70 pounds of concentrates in an hour–it’s both a separator and a concentrator in one self-contained panning machine. Recovers an amazing amount of flour gold so you never lose even the smallest pieces (which all add up!).

The Desert Fox is easy to Use. Fill the tank with 3 to 4 gallons of water. Hook the clips to your 12-Volt battery. Turn on the switch. The wheel starts to rotate and water sprays from the spray bar onto the wheel. Add a scoop of sand every 20 seconds. The GOLD settles to the bottom as the spiral turns and the seven spiral leads pick it up and elevate it to the center hole in the hub where it passes through the hollow shaft into a gold catch cup! It is as simple as that and so user-friendly that you will be an expert gold panner ten minutes after you have used the DESERT FOX for the first time.

Operates on any 12-volt 7-amp DC power source. Use an automotive battery or even a 35 watt solar panel. Ships complete with an easy-to-understand owner’s manual and a video, but this machine is so easy to operate you won’t need them to become a pro! A bag of practice sand containing real placer gold is also shipped with every Desert Fox so you can get acquainted with your new machine and see how efficient and easy it is to use.
