Mountain Goat Trommel / Variable Speed Desert Fox Spiral Panner / Spout + FREE SHIPPING!
The Mountain Goat Gold Trommel is a reverse helix system built on the same principle as the huge mining trommels used by large placer mining companies all over the world, but this is light (16 lbs) and portable, so one person can carry it out into the field. It is a miniature version of the huge trommels used by most major placer mining companies for the last 100 years. It is not to be confused with gravel pit trommels, though, which are designed to classify gravels. Speed up your gold processing work and increase gold recovery with the Mountain Goat Portable Trommel. This machine is aptly named because it can eat almost anything and is light enough to carry up a mountain! This machine is a real workhorse -- it can eat up as much as 2 yards of placer gravel and spit out as little as 10 pounds of concentrates in only 8 hours!
The 4-inch Mountain Goat Trommel is very 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 self-cleaning, which eliminates the need to break down for clean-up as is necessary in sluice box type equipment. The spiral riffles in the trommel tube are .25 inch deep and spaced .75 inches apart. We suggest your placer material be screened to .5 inch or less. There is a nugget trap at the low end of the tube which should be checked regularly for nuggets larger than .25 inch. Do not put rocks larger than half inch into the hopper because the larger rocks can jam the riffles against the spray tube and cause you to have to shut down to clear the jam. Metal retractable legs adjust to 3 heights (see example below). Handle is molded into the trommel body. The Mountain Goat can be used directly in a stream and is a very sturdy machine designed to take a lot of wear and tear! When using the Mountain Goat Trommel away from a running water source, we suggest you purchase a concrete mixing tub (the large size) and a bucket from your local home improvement store such as Home Depot or Lowes. The taillings bucket must be emptied before overflowing to keep gravel out of the water supply. You should also slip a sock over the pump to help keep the the spray system from clogging up.
Manufacturer recommends that you use a 12-volt battery with at least 17 amperes or more, which will run the machine about 3 hours at the right speed. The larger the battery, the longer the machine will run at the right speed. Always make sure that the red clip is on the positive (+) side of the battery. If you revers the clips, the barrel and the pump will turn backwards and no concentrates will be generated. It is not recommended that you run the trommel directly from a battery charger without a battery in the circuit. The trommel is designed to operate on 12 volts, but most battery chargers give out 18 volts, which will cause the Mountain Goat to run 150% the normal speed and kick out the material too fast to be concentrated. TIPS: Use a wetting agent in your water supply to prevent fine gold from floating out into the tailings. If you are running oily beach sand, add a tablespoon of 409 cleaning solution to your water supply. Desert Fox Spiral Panner (variable speed) 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 spiral wheel has 7 separate spirals which pick up GOLD 7 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. The Desert Fox's pitch adjustment and water spray system help you “tune out” the black sand. The Desert Fox Automatic Gold Panning Machine 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!). Operates on any 12-volt automotive battery or even a 35 watt solar panel. Ships complete with an owner's manual and small bag of practice sand containing real placer gold so you can get acquainted with your new machine right away. But the Desert Fox Spiral Wheel is so easy to operate you won't even need it to become a pro! Desert Fox Specifications:
