Cobra Crusher™ Portable Rock Crusher

The Cobra Crusher is a compact, lightweight solution for testing gold-bearing material right where you find it. Designed with portability in mind, this crusher weighs roughly 10 pounds, making it easy to pack into the field without slowing you down.

Built entirely from steel and powered by durable chain hammers, the Cobra Crusher attaches directly to a standard angle grinder (grinder not included) to rapidly break down rock samples into fine material. Its straight feed tube design allows for smoother feeding and makes emptying crushed material quick and hassle-free.

Crusher dimensions:

With the Cobra Crusher, you can crush samples on-site, pan the material, and determine within minutes whether your ore contains recoverable gold. It’s an efficient way to evaluate prospects and focus your time on the best ground.

This portable crusher is also excellent for processing black sands and other concentrates. Whether you’re working deep in the field or back in the shop, the Cobra Crusher delivers fast, reliable sample reduction wherever you go.
