Stamp Mill Crisson Gold Mine

The purpose of the Stamp Mill is to crush gold bearing rock into sand so that it can be processed. The Stamp Mill is a very simple machine. The flywheel builds momentum to turn the cam. The cam lifts the stamps and then gravity drops them back down at a rate of 40 times per minute. It can process approximately 1 ton of rock per hour.
