Cobra Crusher Portable Rock Crusher - FREE SHIPPING! Don’t carry rocks around with you all day or haul them back to camp or your vehicle without first finding out if they have gold or not. Save your valuable time and energy -- this portable rock crusher weighs just 4 pounds can go anywhere and is perfect for sampling! Simply break up some rock, pulverize, pan the crushed material and in minutes find out how much recoverable gold is in the rock in that area. The Cobra Crusher works by attaching to most standard Angle Grinders/ Steel Grinders. Recommended minimum power is 7 amps at 110v for when you're in the shop. Otherwise, a strong 18v or higher professional grade battery powered machine works great for totally mobile prospecting and crushing. Cobra Crusher is interchangeable and can re-attach to either machine in about 3 minutes. The feed tube takes rocks approximately 1" by 1". All steel construction with chain hammers and a set of replacement hammers are included in each order. Don’t be fooled by assays that count gold in sulfide ore that cannot be easily separated. Find out the true recoverable value of your gold per ton with the Cobra portable rock crusher! Pulverize hot rocks that may contain gold Use to high grade old tailing piles and figure out which type of rock has the best gold, and find out if a larger crusher is worth utilizing to run large amounts of material Grind black sands and release any bound up gold from other minerals that would otherwise be discarded Pulverize rocks that may contain gold but are too big to be separated in a sluice, trommel or other machine Samples are incredibly easy to pan or separate by all standard methods as the ground up material is all close to the same size and the lighter material washes away easily. Also, the gold is rolled and rounded during the crushing process which facilitates easier recovery -- unlike thin flakes which can be easily washed away by mistake. Although this unit will quickly grind your samples down to powder, it is meant to be a sampling machine. It is not intended to be a high production rock crusher. The Cobra portable rock crusher weighs just 4 lbs! Grinding chamber dimensions: 7.5 inches across x 3.5 inches wide x 9 inches tall including feed tube. FREE SHIPPING to continental USA! Does not include an angle grinder to use with your Cobra Crusher. Click here to learn more >
