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 about 10 lbs. Grinding chamber dimensions: 7.5 inches across x 3.5 inches wide x 9 inches tall including feed tube.
Product Details This amazing rock crusher is ideal for the gold prospector interested in a light weight and economical high speed machine. Material is gravity fed into the hopper and drops into the center of a high speed tube. The centrifugal force throws the rock into a hardened steel impact wall at speeds in excess of 400 miles per hour.
The average miner can instead purchase a CrazyCrusher manual rock crusher or an electric or gas powered rock crusher and get the gold out in smaller batches. Crushing rock to recover gold can be easier, faster, and much more profitable than prospecting in over worked streams and rivers.
Our Cobra Crusher turns your Angle Grinder into a Mini Rock Crusher Plant with just a squeeze of the trigger. This unit in person is nothing less than amazing, turning sample rocks into a fine powder in just seconds. No longer do you need to haul buckets of rocks home to crush not knowing if they hold Gold or not.Cobra Crusher $449
