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.

Stamp mill

The main components for water-powered stamp mills water wheels, cams, and hammers were known in the Hellenistic era in the Eastern Mediterranean region. Ancient cams are in evidence in early water-powered automata from the third century BC. A passage in the Natural History of the Roman scholar Pliny(NH 18.23) indicates that water-driven pestles had become fairly widespread in Italy by the first century AD: "The greater part of Italy uses an unshod pestle and also wheels which water turns as it flows past

Stamp Mill Digital Desert

A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process. The miner would bring the ore to the mill and load it into the ore car.
