This pneumatic hand held rock crusher for prospecting is 7.75" x 2" with a .400" outside diameter end that mounts in hammer. This air hammer attachment is custom made for the modern day gold prospector or miner. Fits in the average hand held pneumatic air hammer. Fits most pneumatic rock crushers. Pulverizes hard quartz easily. Stands up to abuse of crushing hard rock. Makes sampling ore a piece of cake. Will crush rock below a 60 mesh in seconds. This mining rock crusher takes the work out of crushing rock before panning, processing, or chemical or fire assaying. Very heavy and rugged. Requires little effort for anyone to crush hard rock.
Haven’t been able to use it yet but it is made very well can’t wait to use it. I’ll edit when I do use it.

Needs work
The weight of the hammer is more than the weight of air gun. So it does not deliver the hammering effect to to rock as much. I think it would work better with less weight.

Spiral panning is the best
Bought a spiral panning machine to separate eco waste from ash. It does quick work of it after sifting to 50 or 100 mesh. I got some pay dirt for testing and saw magic. A 1 gram nugget climbed the wheel to my amazement. I did classify the material, fed the material right into the Desert Fox Spiral variable speed rig. I ran the material three times and only found one speck that it missed the first time unclassified. The machine is great, you must get enough power to the pump or the water isn’t even.
