Principles of Stamp Mill Crushing. The stamp battery crushes in two ways, by compression as the result of the impact of the stamp falling upon the ore over the die, and by the abrasion or attrition of the particles of rock upon each other when moving from the impact of the stamp. Crushing by impact is especially the case with coarse ore, but it ...

The mill is a two stamp gold mill, which was used to process gold and silver rich ore by stamping it (or breaking it down) to extract the precious materials. Interestingly enough, though the mill originally came from the town of Marietta, it did in fact process Comstock silver and gold. Funny how things have a way of coming full circle, isn't it?
