Large Rock Crusher
The larger, 3 inch diameter, bore on this hand powered crusher/dolly pot makes it perfect for larger hard rock samples. The unit stands roughly 9" high at the handle and weighs a little over 12 lbs, which should give you an idea of just how much steel is involved in its construction. This is a very solid little ore crusher.
Also great for crushing glass for frit work (fused glass) and other art projects.
