Gold miners and Prospectors are using rock crushers to test material in the field, and recover gold back at home. In most cases, you can take your rock crusher straight from the shipping container and use it in less than half an hour. No wasted time trying to find the right pulleys or chains. Whether you need a manual rock crusher or a motorized version, you get everything you need to start crushing / pulverizing rock and getting the gold right away! A rock crusher can be an invaluable tool. Most of these have been designed and built by miners for miners and prospectors just like you. A tough machine built well and rigorously tested in the field means less work for you.
