How to Choose the Best Rock Crusher for Gold Prospecting
Choosing the best rock crusher for gold prospecting depends on how much rock you need to process and pulverize.
If the plan is to go through tons of rock, purchasing a heavy-duty machine that can quickly process more rock will be much better than attempting to use a small handheld rock crusher. However, if gold prospecting is a hobby, selecting a smaller and cheaper option can suit your needs just fine.
There’s also the issue of rock crushers often kicking up a lot of dust or requiring a lot of power; prospectors should consider this when selecting a suitable machine for their specific needs.
Keep in mind; it is also beneficial to find a smaller rock crusher to test new locations for the potential of paydirt.
